Foreword
Chinese economic reform and opening to the international economy since
the late 1970s have changed the country and the world. The developments
in the steel industry in the reform period are central to those changes, illu-
minative of them, and of immense significance in themselves. This book
throws new light on these historic changes for Chinese and foreign readers
alike.
Chinese civilization was the first to use many of the qualities of iron on
a significant scale. We learn in Chapter 1 that under the Northern Song
dynasty a thousand years ago, China was producing as much iron as
Europe on the eve of the industrial revolution in 1700. In steel- making as
in many things, China lost its head start in the second millennium. China
was not producing much more iron under the late Qing at the turn of the
twentieth century than it had been at the end of the first millennium, by
which time the domestic industry was tiny by modern standards.
The steel industry was an integral part of the industrialization of the
North Atlantic countries and later Japan as modern economic growth
took place from the late eighteenth through the nineteenth and early
twentieth centuries. China was not part of these transformational devel-
opments in the history of humanity until the second half of the twentieth
century. Even then, it endured a long detour under central planning as the
Communist Party established its rule from 1949 through the first three
decades after the revolution – the steel and heavy industry were favoured
by the authorities but still failed to prosper.
In the steel industry as in many parts of the Chinese economy, market-
oriented reform and integrating Chinese production into international
markets spurred productivity growth and the expansion of production.
Chinese steel production rose from 32 million tonnes at the commence-
ment of the reform era in 1978 to 128 million tonnes in 2000, and reached
630 million tonnes in 2010. The immense expansion during the reform
period was accompanied by much higher productivity, higher quality of
output, and much closer calibration of product quality to the requirements
of the market.
These developments in steel were important to Chinese economic
success in the reform era. They were also transformational for the world.

viii The Chinese steel industry’s transformation
The opening of Chinese production to higher- quality and more cost-
effective international supplies of the main steel- making raw materials put
immense pressure on global markets for iron ore and metallurgical coal.
This book tells the story of how all this happened. It is a solid case study
of an industry changing on a scale and at a pace that has no precedent
in global economic history. It will be a useful reference for those seeking
to understand the Chinese experience of economic reform, the impact of
Chinese economic growth on the global economy, and the future trajec-
tory of economic change in China. It will have useful points of reference
for those who specialize in industrial economics, resource economics,
and the economics of the transition out of central planning and inward-
looking policies. It will be of interest to people in the mining industry
who are seeking to understand the immense expansion in opportunities in
their own industry in recent times and especially in the early twenty- first
century. Finally, it should attract the attention of people who are simply
fascinated by the remarkable story of the world’s most populous country’s
belated and subsequent participation in modern economic growth.

Preface
This book is a product of an Australian Research Council (ARC) Linkage
Project (LP0775133) which has been conducted by the team from the
China Economy Program in the Crawford School of Public Policy at
the Australian National University in cooperation with Rio Tinto and
the China Steel Industry Development Research Institute attached to the
China Iron and Steel Association in Beijing.
When we proposed the study to the ARC for funding the project in 2006,
the world economy was experiencing an unprecedented demand shock to
the commodity markets resulting from the rapid growth of the Chinese
economy. As one of the pillar industries, the steel industry plays a key part
through its increasing demand on resources in driving the current resource
boom. The book provides a central reference work on the Chinese steel
industry. Included are both macroeconomic studies of developments in
Chinese resource demand with particular reference to the ferrous metals
complex, and microeconomic studies that utilize the comprehensive firm-
level data to evince new knowledge of both firm and industry performance
with respect to their productivity, technical efficiency, or and industrial
linkages. The book also discusses trade in steel products and the impact of
the restructuring of the industry on the environment.
In completing this work, we have received the support and assistance
from various people and institutions. We would like to thank first our
team members on the project from both Australian National University
and the Chinese steel industry. We gratefully acknowledge the financial
support for the project from the ARC and Rio Tinto. We thank the
China Steel Industry Development Research Institute for providing
some data which were used in carrying out some of the quantitative
analyses in the book. We also acknowledge the arrangement made by
the China Iron and Steel Association for us to visit Shoudu (Capital)
Steel Corporation in Beijing for conducting the firm- level interviews
and seeing the production processes in steel- making. In the course
of completing the project, we ran two workshops in Beijing and one
in Canberra at which the preliminary results and draft chapters were
presented and discussed respectively. We are very grateful to all the
participants in the workshops from both Australia and China for their

1. Steel industry development and transformation in China: an overview
Ligang Song and Haimin Liu
THE DEVELOPMENT OF CHINA’S STEEL INDUSTRY1
The steel industry epitomises traditional industrialization. The major
economies of the United Kingdom, France, Germany, Japan, Korea
and the United States experienced stages of development where the steel
industry played a pivotal role in transforming their economies. The role of
the steel industry in this development is more than symbolic; the technol-
ogy and ready availability of the steel products enabled further economic
growth and development. Industries essential for industrialization and
modernization, such as machinery and building infrastructure, were able
to grow and expand.
China has a long history of iron and steel production. Hartwell (1962,
1966, 1967, cited by Findlay and O’Rourke, 2007) described the remark-
able expansion in Chinese iron and steel production during the Northern
Song dynasty (the period 960–1126 ce): ‘The scale of total production,
and of the levels of output and employment in individual plants, was far
in excess of anything attained by England in the eighteenth century, at the
time of the Industrial Revolution.’ Hartwell estimated that iron produc-
tion in China in 1078 was of the order of 150 000 tonnes annually:
The entire production of iron and steel in Europe in 1700 was not much above this, if at all. The growth rate of Chinese iron and steel production was no less remarkable, increasing 12- fold in the two centuries from 850 to 1050. (Findlay and O’Rourke, 2007, p. 65)
Iron produced during this time was used primarily for agricultural and
military purposes. A thousand years ago China was the largest iron pro-
ducer in the world, but for historical and institutional reasons the iron and
steel industries were not fully developed until centuries later.

2 The Chinese steel industry’s transformation
The development of China’s modern steel industry can be traced back
to the establishment of Hanyang Iron Works in 1890.2 In the following
58 years to 1948, China’s total accumulated pig iron output reached 22
million tonnes, and crude steel nearly 7 million tonnes. The highest indi-
vidual year was 1943, with iron production reaching 1.3 million tonnes
and steel 0.9 million tonnes. During this period, the steel industry was
located mainly in the Anshan area of North- East China, producing more
than 90 per cent of the country’s total steel output.
The wars which wracked the country for much of the 1940s almost
ruined the steel industry. When the People’s Republic of China (PRC) was
founded in 1949, the national total production of pig iron was only 250 000
tonnes. In the same year, the country’s production of steel was 158 000
tonnes, accounting for 0.2 per cent of the world’s total steel production
and ranking twenty- sixth in the world.
Yet production recovered quickly and by the end of 1952 the country
had restored and expanded 34 blast furnaces and 26 open hearths. The
national total production of iron, steel and rolled steel in 1952 was 1.9,
1.4 and 1.1 million tonnes, respectively, topping all previous records.
Meanwhile, the regional distribution of steel production showed no sig-
nificant changes, with 70 per cent being produced in the north- east, 23 per
cent in the east and north, and 7 per cent in the hinterland.
In the 30 years following the founding of the PRC, the steel industry was
regarded as a pivotal link for industrialization. With the help of the former
Soviet Union, a generally complete steel industry system was formed with
‘three big, five middle and 18 small’ steel enterprises,3 but this burgeoning
steel industry development faced further setbacks with the implementation
of the ‘Great Leap Forward’ and later the ‘Cultural Revolution’.
The highly centralized planned economic system hampered the develop-
ment of productive forces in the steel industry, albeit after having played
a major role in restoring production in the 1950s. Consequently, the
industry saw very slow technological progress. In 1978 China’s total steel
production was only 32 million tonnes, less than three weeks of current
output levels. The per capita steel production was merely 33 kg, a fifth of
the world average levels. The industry’s technology, equipment, product
variety and quality, as well as technical and economic indicators, all lagged
far behind developed countries. For example, when the world average
ratio of open- hearth steel- making to total steel- making fell below 20 per
cent in the late 1970s, China’s ratio still stood at 35.5 per cent. When the
ratio of continuous casting was more than 50 per cent in Japan and 30 per
cent in Europe, China’s was merely 3.5 per cent. As a result of obsolete
technologies, out of total production, the energy consumption per tonne
of steel was as high as 2.52 tonnes of standard coal, with the yield of crude
M3021 - SONG 978184844658 PRINT.indd 2M3021 - SONG 978184844658 PRINT.indd 2 23/11/2012 14:5123/11/2012 14:51
Overview of the Chinese steel industry 3
steel in rolling finished steel around 74 per cent.4 Furthermore, 28 per cent
of steel consumption relied on imports in 1978, costing foreign exchange
earnings.
The reform and opening- up policy of 1978 brought China into a new era
of growth and development. The development of the steel industry since
then can be divided broadly into three stages.
The first stage was the early period of reform and opening up, running
from 1978 to 1992. This stage is characterized as a gradual transition from
a highly centralized planned economy towards a preliminarily established
socialist market economy. Experiments on enterprise autonomy, profit
contracts and managerial responsibility systems were carried out in the
steel industry. Shoudu (Capital) Steel Corporation, the first batch of large
state enterprises experimenting with extended decision- making powers,
implemented the managerial responsibility system of contracting in 1981.
The new system brought firm and worker initiatives into play. As a result
the firm’s steel output and economic performance improved quickly.
Afterwards the contracted responsibility system spread step by step across
the industry. By the end of 1992, 103 out of 110 key steel enterprises had
implemented managerial responsibility system reforms.
During this reform stage, China changed from a rigid system of state-
fixed prices and centralized purchase and sales to allowing steel enterprises
to purchase raw materials in the market. It also allowed them to sell a
certain proportion of planned production, and all the excess steel prod-
ucts, through their own channels at market prices, which were usually
higher than planned prices. The country gradually lowered the ratio of
mandatory planned rolled steel, reaching 20 per cent in 1992. These meas-
ures boosted incentives for production in the industry.
These steel enterprises were allowed to use retained profits for their
expansion, bonuses and employee welfare payments. The industry’s
retained profits in 1992 reached 5.8 billion yuan, accounting for 56 per
cent of total profits. Of retained profits, 3.8 billion yuan was used for
enterprise development, providing 26 per cent of funds sourced from both
the government and enterprises for upgrades and renovation. The average
annual incomes for workers in the steel industry increased from less than
500 yuan in 1978 to around 3800 yuan in 1992.
Financing for investment in the industry was transformed from relying
heavily on state allocations before 1978 to relying on the enterprise itself
by self- raising, bank loans and foreign capital. At the same time steel
enterprises were permitted to make independent decisions and undertake
technical innovations. These reforms adjusted the power–responsibility–
favour relations between the state and enterprises. This made it clear that
the enterprises were the principal point of interest.

4 The Chinese steel industry’s transformation
The steel industry also worked towards opening up. During the 14 years
from 1978 to 1992, more than 700 advanced technologies were introduced
and US$6 billion in foreign capital was utilized. In particular, two modern
large steel enterprises, Baoshan Iron and Steel Corporation (launched in
1978 and put into operation in 1985) and Tianjin Seamless Steel Tube
Corporation (launched in 1989 and put into operation in 1996), were
established. Meanwhile, many old steel plants were rebuilt and restruc-
tured. These notable changes to the technology structure of the country’s
steel industry saw the gap between it and world- class practices narrow.
This initial stage (1978–92) saw significant achievements in outputs. By
1992 there was a 1.6- fold increase in steel production; the domestic market
share had increased by 17 per cent, the ratio of open- hearth steel- making
to total steel- making was reduced to 11 per cent, the ratio of continuous
casting to the total rose to 30 per cent, and the total production energy
consumption per tonne of steel output fell to 1.6 tonnes of standard coal
or by 62 per cent.
Despite greater autonomy granted to enterprises under the contracted
responsibility system, China’s steel enterprises were still subordinate to
the government. Further, varying contractual conditions together with the
dual- track steel price system caused a disparity among steel enterprises in
terms of performance. This disparity induced some firms to bargain with
the government, distorting the market’s role in resource allocation.
The second stage was the early period of establishing a socialist market
economy from 1993 to 2000. In this stage, the main focus of China’s
reform was the setting up and improvement of market systems. Key to
this was establishing a complete modern enterprise system – separating the
roles of government as the owner and manager of state- owned enterprises
(SOEs), and making the enterprises the true market entities responsible for
their own profits and losses.
As for the steel industry, mandatory plans for production and sales were
abolished in 1993, and the dual- track steel price system ended. Thereafter,
steel enterprises made their own decisions on production and sales based
on market demand. The steel market developed rapidly in all parts of
China. With the development of the securities markets, transforming into
a joint- stock company and listing on the stock markets became the new
financing channel for a Chinese steel enterprise. By the end of 2000 there
were 27 steel enterprises listed in the domestic and/or international secu-
rities market. This raised significant investment funds for development,
and more importantly improved companies’ corporate governance and
management skills.
At the same time, the steel industry not only continued to utilize foreign
capital to upgrade obsolete technology but also utilized overseas resources
M3021 - SONG 978184844658 PRINT.indd 4M3021 - SONG 978184844658 PRINT.indd 4 23/11/2012 14:5123/11/2012 14:51

to make up for the domestic scarcity of raw materials. Total imports of
iron ore reached 70 million tonnes in 2000, increasing nearly eightfold
compared with 1978. Some enterprises began to buy or set up jointly
owned iron ore production bases in Peru and Australia.
During this period the steel industry faced many challenges, including
continuously declining steel prices, chain debts and the periodic return of
overcapacity. It also went through a difficult macroeconomic environ-
ment, with overheating just before the Asian financial crisis in 1997 and
then a fall in output in the aftermath. Nevertheless, the steel enterprises
streamlined their businesses, readjusted their product mix and carried
out technical innovations around energy savings and cost reductions. As
a result the industry’s technological bases and ability to adapt to market
changes improved greatly.
Along with the steel enterprises’ own efforts the Chinese government
offered them supporting policies, such as debt- to- equity swaps and dis-
counts for technological transformation. These policies helped China
become the world’s largest steel- producing country in 1996, with total
output surpassing 100 million tonnes. Its steel production in 2000 reached
128 million tonnes, an increase of 59 per cent from 1992.
This stage saw the fastest structural adjustment of the steel industry.
By the end of 2000, open- hearth steel- making was almost eliminated, five
years earlier than planned; the ratio of continuous casting reached 87 per
cent, surpassing the 75 per cent target and catching up with world aver-
ages; and the total energy consumption per tonne of steel output fell to 885
kg of standard coal, a decrease of 56 per cent from 1992.
The third stage has been the deepening of reform and fast economic
growth period since 2001. With the new century, the Chinese iron and steel
industries experienced significant and influential external developments.
Following China’s entry into the World Trade Organization (WTO) in
2001, market laws and regulations were geared towards reaching inter-
national standards, integrating the steel industry further into the world
market. China’s manufacturing share increased from about 5 per cent in
the mid 1990s to over 17 per cent of the world’s total manufacturing in
2009. Over the reform period, the urbanization ratio rose to 46 per cent
in 2010, rising from only 19 per cent back in 1978, transferring nearly 300
million people from rural to urban areas.5 This large- scale urbanization
boosted the investments in housing and infrastructure.6 All these devel-
opments led to the rapidly increasing demand for steel from domestic
sources. For example, steel consumption increased by 16 per cent per
annum from 2000 to 2010. In meeting this rising demand, the industry’s
total investment increased from 36.7 billion yuan in 2000 to 453.1 billion
yuan in 2010, with an annual growth rate reaching 28.5 per cent over this
M3021 - SONG 978184844658 PRINT.indd 5M3021 - SONG 978184844658 PRINT.indd 5 23/11/2012 14:5123/11/2012 14:51
6 The Chinese steel industry’s transformation
period. Steel production rose as a result. According to the figures from the
statistical yearbooks, in 2010 the ferrous metal industry accounted for 4.6
per cent of the total industrial employment, 8.3 per cent of the total indus-
trial value added, 25 per cent of total industrial energy consumption and
between 10 and 16 per cent of the total emissions of the main pollutants
from the industry sector.
Further trade liberalization has led to the sharp reduction of import
duty as well as the complete abolition of quantitative import restrictions,
which has exposed steel enterprises to the fierce competition of the inter-
national market. China’s rapid economic growth led to rapidly increasing
demand for steel from domestic sources. The increased competition from
the market entry of those non- state firms has forced the large and medium
state- owned steel firms to deepen the corporate reform, to include share-
holding and the separation of government functions from management.
To further separate government functions from enterprise management,
the Bureau of Metallurgical Industry at both state and local level was dis-
solved. Instead, the China Iron and Steel Association,7 a self- regulatory
organization of the steel enterprises, acted as a bridge between enterprises
and government.
Steel enterprise reform proceeded towards developing a more diver-
sified ownership structure. By the end of 2010 more than 50 steel
enterprises were listed on stock markets and 50 per cent of large and
medium- sized steel enterprises, in terms of operating revenue, were trans-
formed into joint- stock companies. Private steel enterprises also grew
rapidly. Non- state enterprises accounted for about 45 per cent of the
total output of the steel industry in 2010. Reorganization and mergers
and acquisitions (M&As) have also been part of the process of industrial
agglomeration.
The steel industry is accelerating its pace of globalization. The China
Iron and Steel Association and the largest steel enterprises became
members of the World Steel Association (WSA) at the end of 2004. They
have taken part in worldwide dialogue and negotiations, and adopted
common actions as a response to resource, environmental and market
changes. The rapid expansion of steel production has forced the industry
to utilize overseas resources on an unprecedented level. Imported iron ore
now accounts for two- thirds of the total consumption in the steel industry.
For example, to produce 567 million tonnes of steel in 2009, China’s steel
industry consumed 850 million tonnes of iron ore, of which 602 million
tonnes were imported in that year, raising its import dependence ratio for
iron ore to 74 per cent. The share of China’s consumption of iron ore in
world total iron ore consumption increased from 20 per cent in 2000 to
56 per cent in 2009. Many steel enterprises are also undertaking outward

direct investment in the mining sectors in order to secure stable and long-
term resource supplies (Song et al., 2011).
ACHIEVEMENTS IN THE REFORM PERIOD
Any shortage of steel in China may now be consigned to history. Since
the reform and opening up of 1978, and especially since 2000, China’s
steel production capacity has expanded rapidly. The industry underwent a
period of extraordinary growth in both total sales and total profits which
increased at an average annual rate of 32 and 44 per cent respectively over
the period 2001–07.8 The end of 2010 saw China’s total steel production
reach 630 million tonnes, 18 times the output in 1978. The crude steel pro-
duction grew at an annual growth rate of 17.2 per cent after 2001. China’s
share of global steel production increased from 4.4 per cent in 1978 to 15
per cent in 2000 and to 45 per cent in 2010, a share which has been unpre-
cedented in the entire history of industrialization.9
In the past, China relied on imported steel to fill the supply shortfall.
Gross imported billet and rolled steel in the period from 1978 to 2004
amounted to 478 million tonnes. After deducting exports, net imports
were 352 million tonnes, accounting for 12.6 per cent of China’s total con-
sumption of crude steel. Increasing exports and decreasing imports of steel
products found China realizing a rough balance in 2005, becoming a net
exporter of steel products in 2006. Such an historic change implies China’s
steel industry is capable of meeting the needs of the country’s economic
development. It also suggests that the international competitiveness of
Chinese steel products has improved immensely.
Iron and steel production quality and variety have increased dramati-
cally. Currently China’s self- sufficiency rate in most steel products exceeds
100 per cent. Only some high- value- added products, such as cold- rolled
ordinary steel board (strip) and electric steel, are net imported. Most steel
products used in industry – such as machinery, automobiles, shipbuild-
ing, home appliances, oil, electricity and railways – are home- made. The
product qualities are sufficient to meet the basic needs of those industries.
Some varieties have even reached internationally advanced levels. China’s
steel exports have gradually shifted from producing long products to pro-
ducing higher- value- added sheets and pipe products.
The industry has also achieved enhanced standards in terms of technol-
ogy and equipment, and an increased localization rate. The accumulated
fixed- asset investments of the steel industry, which were a mere 60 billion
yuan in the first 30 years from 1949, reached 2.6 trillion yuan from 1978 to
2010. In addition to the establishment of world- advanced steel enterprises

8 The Chinese steel industry’s transformation
– such as Baoshan Iron and Steel Corporation and Tianjin Seamless
Steel Tube Corporation, and some private steel enterprises – most of
those investments went to the upgrading of outdated equipment and the
restructuring of old steel enterprises. From 1978 to 2010 the number of
large blast furnaces over 1000 m3 in volume grew from 10 to 260, of which
28 were over 3000 m3; the ratio of continuous casting grew from 3.5 per
cent to 98 per cent, which is above the world average. The modern steel
industry is encouraged to rely more on autonomous innovation rather
than depend solely on introduced techniques and equipment. In 2010
small and medium metallurgical equipment is domestically produced,
while the localization rate of large metallurgical equipment is over 90
per cent.
The industry also experienced a remarkable rate of technological
progress, resulting in improved technical and economic indicators. Many
indicators of domestic productivity are outstripping those of developed
countries. For example, since 1978 the overall ratio of rolling steel being
produced has increased to over 95 per cent from 75 per cent; total pro-
duction energy consumption per tonne of steel has fallen from 2.5 tonnes
of standard coal to 605kg of standard coal; freshwater consumption per
tonne of steel has fallen to 4 tonnes; and labour productivity per tonne per
person- year has increased from 33 tonnes to 400 tonnes.10
NEW CHALLENGES AND READJUSTMENT
The market- oriented industry, corporate reform and opening- up policy
have been the decisive factors in the development of China’s steel indus-
try. Enterprises were released from the rigid centralized planning system,
boosting competitiveness (enhanced in large part by the low cost of
labour) and allowing the development of profit- making incentives, leading
to enhanced performance. The establishment and development of the
market system enabled and urged steel enterprises to face the challenges
of market competition, which again improved their productivity and effic-
iency. China’s rapid economic growth provided a huge demand for steel
products, which gave impetus to the rapid growth and expansion of the
industry.
Despite these achievements, China’s steel industry still faces many chal-
lenges which demand deepened reform and consolidation. The state his-
torically has dominated the steel industry. The transformation of SOEs in
the past turned many steel enterprises into market players. However, they
are still constrained by the traditional state- dominant system in orienting
development strategies, making investment decisions, conducting M&As,
M3021 - SONG 978184844658 PRINT.indd 8M3021 - SONG 978184844658 PRINT.indd 8 23/11/2012 14:5123/11/2012 14:51

restructuring, appointing senior managers and employing workers. As a
result the industry’s overall economic performance remains behind devel-
oped countries, by some margin. Private steel enterprises, although more
flexible, require further improvement in implementing modern technol-
ogies, following codes of conduct and upgrading management skills
according to market principles.
Market competition is the catalyst for improving the overall quality
of the steel industry, but the way competition has worked in it has been
complicated by the cyclical fluctuations of the macroeconomy. In times
of prosperity, steel enterprises have tended to assess the market prospects
overoptimistically and expand production blindly. This has resulted in
large amounts of overinvestment and backward production capacity
being utilized. In times of weak demand, disorderly competition by cutting
prices has occurred, and the industry has sometimes relied upon govern-
ment intervention to alter the supply–demand balance. These behaviours
and fluctuations have added to structural adjustment costs, slowed down
technological progress and wasted social resources.
The domestic market is still segmented and the degree of industrial
concentration is quite low. In 2000, the share of steel output by the top
ten firms and the top four in total output were 49 and 32 per cent, respec-
tively. The years to 2006 saw a falling ratio of industry concentration, to
35 per cent for the top ten and 19 per cent for the top four, owing to the
large number of small firms entering the market seeking to meet the rising
domestic demand for steel. The benefits of industrial consolidation in
responding to the problems associated with the use of materials, energy
and the environment thus led to the ratio of industry concentration rising
again, in 2010 increasing to 49 per cent for the top ten and 28 per cent for
the top four (the latter is still below the level of 2000). Despite the progress
made, the industry concentration ratio is far below that of developed
countries, which ranges between 70 to 80 per cent for the top four or five.11
The rapid increase in demand for steel products and the rising prof-
itability of the industry stimulated the entry of many non- state small
firms, usually supported by local governments for the purposes of
increasing local employment and taxation. These small firms tend to
use backward production capacities and technologies, adding further
difficulties to restructuring the industry. This is the root cause of the
problems associated with capital misallocation, low quality standards,
duplication of construction effort and blind expansion of production
capacity, as well as structural overcapacity. These problems are intrinsi-
cally related to issues of wasteful investment, inefficiency in material use
(including energy, water and electricity) and environmental problems.
Such industrial segmentation also hampers the technological progress
M3021 - SONG 978184844658 PRINT.indd 9M3021 - SONG 978184844658 PRINT.indd 9 23/11/2012 14:5123/11/2012 14:51
10 The Chinese steel industry’s transformation
as smaller firms lack the resources for research and innovation. The
industry needs further structural reform to address these problems at
the microeconomic and industrial levels, and the government needs to
do its part by strengthening the existing regulatory system with respect
to market entry and the environment, and reforming its relationship
with enterprises.
The industry faces the pressure of rising costs of production resulting
from the high prices of energy, water and iron ore in addition to the rising
costs of labour and transport on which the industry heavily depends.12
These rising costs of production have further squeezed the profit margin
for the industry. When the industry passes on the price rises to the con-
sumers, it affects future demand for steel. To cope with this, the strategy
for the industry needs to be shifted from an emphasis on pure expansion
of scale to a focus on optimization of the structure of production includ-
ing the product structure through industrial upgrading and technological
change. The industry is also compelled to reduce the costs of produc-
tion, increase productivity and international competitiveness through, for
example, an increase in industrial research and development (R&D) and
improved corporate management. The introduction of advanced foreign
technologies, equipment, capital and resources has also helped the indus-
try to realize a leapfrogging developmental path.
An offsetting factor which helps the industry to reduce resource intensi-
ties, including primarily the use of iron ore in producing steel in the future,
is that there will be an increasing proportion of steel demand which is met
by scrap. China is still at the phase of industrialization where the accumu-
lated stock of steel is not sufficiently large for more scrap to be recovered
and used in steel- making. In 2008, the proportion of electric furnaces
using scrap for making steel was only 9 per cent of total steel production
in China, which was far below the world average level of 31 per cent. In the
same year, the proportion in the United States was 58 per cent while the
proportion in the European Union (15 countries) was above 40 per cent
(Yang, 2010).13
China paid an excessive environmental price for the rapid develop-
ment of its industries, including the steel industry, with an environmental
ramification well beyond its border. China became the largest global
carbon emitter in 2007,14 and yet the country is still in the middle phase
of industrialization (according to the current level of per capita income)
with the growth and expansion of the manufacturing sector (especially
heavy industries) generating more emissions. China needs, and has an
obligation to achieve, emission reduction targets as part of the global
effort in confronting the challenge of climate change. The government
needs to be clear about the scale, pattern and pace of growth, which will
M3021 - SONG 978184844658 PRINT.indd 10M3021 - SONG 978184844658 PRINT.indd 10 23/11/2012 14:5123/11/2012 14:51

meet China’s future demand for steel while ensuring that the industry’s
development is conducive to environmental protection. At the moment,
the government’s macrocontrol policies and regulatory measures curb the
development of large enterprises, but leave the small ones and low- level
projects unaffected. This leads to a high proportion of backward and
low- level production capacities being utilized in the industry. China has
to rely on exporting to absorb the surplus of steel after meeting domestic
demand.
The share of steel exports in total world steel production has experienced
both rising and falling trends in recent decades. In 1975 the share was 23
per cent, then rose to a peak of 40 per cent in 2000. It fell to 34 per cent in
2008 and further to 26 per cent in 2009 (World Steel Association, 2010).15
In contrast to this trend, China has been a net exporter of steel since
2005. In 2008, Chinese net exports were 40.7 million tonnes of steel, and
ranked number one in the world, followed by those of Japan (32.4 million
tonnes), Ukraine (26 million tonnes) and Russia (23 million tonnes). In
the same year, the United States was the world’s largest net importer of
steel (12.7 million tonnes) followed by the European Union (27 coun-
tries) with 11.4 million tonnes, United Arab Emirates (10 million tonnes),
Thailand (9.4 million tonnes) and South Korea (8.8 million tonnes).16
Exporting steel products to world markets helps ease the problem of
industrial overcapacity. However, an increase in exports of steel has made
industrial restructuring (including ownership reform, industrial concen-
tration and technological progress) a less urgent task. It has also made
the tasks of reducing the resource and pollution intensities of the industry
more difficult. Furthermore, China’s exports of steel are causing trade
frictions with others, especially those to developed countries such as the
United States and the European Union. The government has adopted
various measures such as the imposition of export taxes and the reduction
of export tax rebates for certain products in order to limit the increase in
exports of steel. However, the industry’s low cost and other advantages
will continue to run their course despite the fact that the government
intends to see the role of the steel industry as essentially to meet domestic
demand. The challenge therefore is how the Chinese government could
bring steel production back in line with the changes in domestic demand
without relying too much on exports.17
China will continue to be the largest steel producer in the world for
the time being, driven largely by the ongoing process of urbanization,
industrialization and her integration with the global economy. China’s
level of per capita income needs to be tripled from the current level before
the peak level of metal intensity is attained, something which is forecast
to happen around 2024. By then, China’s total steel output will be in the
M3021 - SONG 978184844658 PRINT.indd 11M3021 - SONG 978184844658 PRINT.indd 11 23/11/2012 14:5123/11/2012 14:51
12 The Chinese steel industry’s transformation
vicinity of 1 billion tonnes (McKay et al., 2010). This prospect of China’s
future metal intensity and the magnitude of its output raises an important
question as to how the world supplies of key resources including energy
and minerals, as well as the environment, will accommodate the continual
growth in China. As Garnaut has said (2012), ‘one only has to identify
the possibility of China absorbing more resource- based products than
the currently developed world to raise some fundamental questions about
“limit to growth”’. The steel industry can do its part in overcoming this
limit to growth in the process of China’s modernization as the industry is
scale- , capital- , resource- and pollution- intensive. In fact, the industry will
be compelled to do so because in recent years the Chinese government has
promulgated a number of key laws and regulations with respect to energy
use and the environment such as the ‘Environmental Protection Law’, the
‘Law for Prevention of Air Pollution’, the ‘Law for Prevention of Water
Pollution’, the ‘Law for Prevention of Solid Waste Pollution’ and the ‘Law
for Energy Saving’. Given the current level of the industry development, it
is a challenging task for the industry to comply fully with the requirements
of these laws.18
The world economy has entered a period of development requiring huge
adjustment and rebalancing. Resource scarcity, demographic change,
climate change and global imbalances are global shared concerns. The
Chinese government is responding to these changes by transforming the
model of its growth and development (Song, 2010). Accordingly, the
requirements for the steel industry have also changed, as is reflected in
a lower level of resource intensity, the higher variety and quality of steel
products, and an increasing environmental constraint. These changes call
for optimizing the industrial structure, enhancing technological progress,
improving corporate management, and, most fundamentally and cru-
cially, deepening the structural reform of the steel industry, including its
ownership and concentration.
STRUCTURE OF THE BOOK
The aim of this volume is to provide a central reference work on the
Chinese steel industry. The chapters fall loosely into three groups. The
first group, comprising Chapters 2 and 3, are macroeconomic studies of
developments in Chinese resource demand with particular reference to
the ferrous metals complex. Chapter 2, by Huw McKay, utilizes an inter-
national comparative framework with a strong historical bent. McKay
argues that while China’s experience with metal intensity currently resem-
bles that of Korea, this is a temporary phenomenon. China’s eventual
M3021 - SONG 978184844658 PRINT.indd 12M3021 - SONG 978184844658 PRINT.indd 12 23/11/2012 14:5123/11/2012 14:51

path is expected to borrow from both the US and Japan, but will retain
Sino- specific characteristics.
Chapter 3, by Jane Golley, Yu Sheng and Yuchun Zheng, is an attempt
to apply the logic of provincial convergence to the metal intensity field.
The authors showcase a novel approach to the estimation of underly-
ing steel consumption by province. The inferences emanating from this
subnational approach make a fascinating counterpoint to the discussion
in Chapter 2. Readers who come to the study of China with a belief that
its industrialization path is sui generis will find much to commend in the
provincial approach adopted here.
The second group, comprising Chapters 4, 5 and 6, are microeconomic
studies utilizing granular data to evince new knowledge of both firm and
industry behaviour. All three are co- authored by Yu Sheng and Ligang
Song. Based upon the unique findings presented, a number of policy
recommendations are put forward in this cluster of chapters.
Chapters 4 and 5 should be considered as a pair. Utilizing firm- level
data, the authors investigate productivity outcomes of all steel firms in
the structurally significant period of 2000–03, and efficiency outcomes of
state- owned enterprises (SOEs) in the period 1999–2005. This era was an
immensely important time for the industry. Coming out of the turmoil of
the 1990s, with the twin shocks of the 1992–94 boom–bust cycle and the
Asian financial crisis, and then being subjected to a further disruption in
the form of the ‘tech wreck’ recession, the industry was also confronted
with an imperative requirement for major structural adjustment and a dra-
matic transformation of ownership. The situation was clearly extremely
fluid. Understanding the industry at this time is crucial to making sense of
developments later in the decade.
Sheng and Song show that these various stresses encouraged a number
of firms to change their behaviours resulting in both level and aggregate
gains in both productivity and efficiency. In addition to rigorously docu-
menting these trends, the authors add to our knowledge by splitting their
sample between large and medium firms and their smaller counterparts, as
well as discussing the nature of firm ownership. It turns out that the deter-
minants of productivity are very different when the size of the firm is con-
sidered, a finding that brings with it powerful implications for industrial
policy both inside China and in other developing and/or transition econo-
mies. Along the way, Sheng and Song are able to make some methodologi-
cal improvements to the techniques utilized in previous literature, and are
thus able to correct the prior tendency to understate the contribution of
capital to output – which gives profound implications for the analysis of
returns to scale in the industry.
Chapter 6 studies the backward and forward linkages of the steel
M3021 - SONG 978184844658 PRINT.indd 13M3021 - SONG 978184844658 PRINT.indd 13 23/11/2012 14:5123/11/2012 14:51
14 The Chinese steel industry’s transformation
industry, utilizing industry- wide census data. The results indicate strongly
that steel is vital to the very fabric of the Chinese economy. After esti-
mating productivity spillovers from steel to other industries, the authors
conclude that upstream and downstream industries have seen opposite
effects of the increase in steel industry efficiency. Downstream firms
have been shown to improve their productivity as a response to the steel
industry, but upstream firms have suffered. The authors conclude that the
continual increase in import penetration in upstream sectors accounts for
this result.
The third group, comprising Chapters 7, 8 and 9, offer three fresh prac-
tical perspectives on the industry. Chapter 7, by Haimin Liu and Ligang
Song, details the nature of China’s international trade in ferrous metals
and points out that the net export status achieved by the industry in the
lead- up to the financial crisis is neither sustainable nor desirable. Liu and
Song highlight the difficulties for the Chinese government in bringing steel
production back into line with domestic demand, and suggest the ways
forward to align the balance between demand and supply of steel products
without relying excessively on exports.
Chapter 8, by Yu Sheng and Ligang Song, focuses on the determinants
of the iron ore trade. The authors consider time- series data from 1960,
capturing both the autarkic and more open eras of Chinese industrializ-
ation. Their conclusion – that domestic demand for ferrous metals is the
principal determinant of China’s burgeoning imports needs – should
not be controversial, given China’s long- running net import position.
Additionally, the study highlights that the relatively low quality of China’s
own iron ore reserves, coupled with its very strong demand and lack of
scrap resources, leads to a position where import demand is inelastic to
price. That result may embolden iron ore negotiators who sit on the supply
side of discussions.
Chapter 9 by Guoqing Dai and Ligang Song argues that while the
steel industry has already achieved a great deal in terms of reducing its
environmental footprint, greater efforts are required in moving forward.
At the national level the steel industry is a very prominent consumer
of energy and a large emitter of pollutants and waste water. Therefore,
progress in improving the steel industry’s own environmental perform-
ance through enhanced technological progress, economies of scale
and corporate management will contribute strongly to the aggregate
outcome. Put another way, if the steel industry is unable to improve
its performance, it will be difficult for the country as whole to meet its
aspirational goals.

2. Hanyang Iron Works was established in 1890 and went into operation in 1894. It was the first integrated iron and steel works in modern China and was also one of the largest in Asia, with an annual output of 60 000 tonnes of steel.
3. Three big: Anshan, Wuhan and Baotou Iron and Steel Company; five middle: Taiyuan, Chongqing, Beijing Shijingshan, Maanshan and Xiangtan steelworks; 18 small: Handan, Jinan, Linfen, Xinyu, Nanjing, Liuzhou, Guangzhou, Sanming, Hefei, Jiangyou, Wulumuqi, Hangzhou, Echeng, Lianyuan, Anyang, Lanzhou, Guiyang and Tonghua steelworks.
4. The ratio increased to 94 per cent in 2010. 5. The urbanization ratio is defined as the ratio of urban population to total population. 6. According to the data from China Iron and Steel Association (CISA), the housing
sector consumed more than 50 per cent of steel produced in recent years. 7. The CISA is a national steel industry organization. The members consist mainly of steel
production enterprises, which account for 80 per cent of the national total steel output. Some trading firms, equipment manufacturers, construction firms as well as consulting companies are also members of the CISA.
8. The profit rate from sales grew by an average of 9.1 per cent per annum over the same period.
9. For a historical comparison, the United Kingdom was the largest steel producer in the world before the 1890s. In 1885, the UK’s steel output accounted for about 30 per cent of the world total steel output That top position was then taken by the United States from 1886 to 1971, and then the former Soviet Union from 1971 to the late 1980s, and Japan for only a brief period in the early 1990s (Yang, 2010).
10. Chapters 4 and 5 in this volume detail the causes of these improvements in performance. 11. For example, Japan’s top five firms produce 79 per cent of the total steel output;
Korea’s top two firms produce 80 per cent of its total output (Yang, 2010).12. World iron ore prices (the long- term contract prices) rose by 8.9 per cent in 2003, 18.6
per cent in 2004, 71.5 per cent in 2005, 19 per cent in 2006, and 9.5 per cent in 2007. In 2008, the prices rose by 65 per cent for Brazilian ore and 79.8 per cent for Australian (CISA report, 2008).
13. The world average proportions of electric furnaces in steel- making were gradually increasing over time, rising from 14 per cent in 1970 to 22 per cent in 1980, then further to 28 per cent in 1990 and to more than 30 per cent in 2006 (CISA report, 2008).
14. An estimate by the World Steel Association shows that China’s steel industry was ranked number one in terms of its carbon emissions among all the steel industries in the world in 2007. China’s emission share accounted for about 51 per cent of the total emis-sions emitted by world steel industries in 2007 followed by the European Union (12 per cent), Japan (8 per cent), Russia (7 per cent), the United States (5 per cent) and others (17 per cent) (CISA report, 2008).
15. The quick fall in the share of exports of steel in total production in 2009 over the pre-vious year may be due largely to the impact of the global financial crisis (GFC).
16. World Steel Association (2010).17. See Chapter 5 for a detailed discussion of this issue.18. The International Iron and Steel Industry Association (IISI), at a meeting held in
Berlin, Germany, in October 2007, published the statistics on its members’ CO2 emissions. IISI’s 180 members have agreed on the plan for reducing CO2 emissions. According to the data, only 20 per cent of the steel production in China could meet the requirements set by IISI in 2006 (CISA, 2008).

2. Metal intensity in comparative historical perspective: China, North Asia and the United States
Huw McKay
INTRODUCTION
The aim of this chapter is to shed light on China’s future path of steel
and base metal intensity by referencing the experience of relevant peers
through their point of entry into the global strategic transition (Snooks,
1998) – which is the vehicle by which industrialization has been dissemi-
nated round the world – and beyond.
Will China follow a path like Korea, which has stayed in the metal-
intensive sweet spot for a sustained period of time; or will it touch only
briefly on the middle- income sweet spot of metal intensity en route to the
current resting place of the European economies and their offshoots? Will
it eventually sit just on the more metal- intensive side of the high- income
cohort, in a place similar to that where Japan resides?
These questions go to the very roots of Chinese long- run economic
strategy and performance. The immense scale of China’s megastate means
that its strategic choices will generate substantial externalities that will
require assertive responses from others. A better understanding of the
path of metal intensity through time in a broader range of countries would
be a great help to those tackling the immense task of meeting and respond-
ing to China’s long- run metal demands.
A broad conclusion of the analysis is that China is unlikely to follow the
Korean path once it moves deeper into middle- income status. The superfic-
ially attractive correlation between the Korean and Chinese paths, based
on limited time series, is perceived sceptically from the medium- term point
of view. The final path is likely to borrow from certain aspects of the expe-
rience of the United States and Japan, but the Chinese path will be distinc-
tive. The United States is an apposite comparison as an economy built
on a continental scale with a low population agglomeration ratio, while
Japan is relevant due to the explosive but finite gains in world export share

18 The Chinese steel industry’s transformation
it enjoyed as its technological strategy unfolded, and the constraints that
high population densities place on urban lifestyles. Together, these econ-
omies define some reasonable parameters for considering the Chinese case.
While the United States and Japan are clearly relevant to a medium-
term assessment, evidence on metal intensity from these jurisdictions
should not be deterministic for our purposes. The sketch of Chinese metal
intensity assembled here assumes a strong increase until the period of 2015
to 2020, then a flattish peak emerging from 2020 to 2025, before an orderly
decline develops in the second half of the 2020s. These dates are informed
by Sino- specific analysis with pragmatic, selective input from historical
case studies.
The national relationships between metal intensity and standard macro-
economic variables are complex and idiosyncratic. The firm implication
from them is that each nation’s industrialization process and its relation-
ship to metal intensity is sui generis and should be treated as such. Any
attempt to generalize across this field should be carried out with extreme
caution. While the investigation of intranational (provincial) data on
metal intensity has much to recommend it, at this stage the results derived
should be regarded as tentative rather than conclusive.
METAL INTENSITY IN THE UNITED STATES: THE CASE FOR THE ‘KUZNETS CURVE FOR STEEL’
The longest national time series available in this field is for steel use per
capita in the United States. Here we analyse the US experience in the
context of the Kuznets formulation.
A Kuznets relationship is represented by a second- order polynomial,
with income per capita and its square term on the right- hand side of the
equation and the relevant development metric on the left. To test for this
relationship in the metal field, we regress the Hodrick–Prescott filter of
annual steel use per capita in the United States from 1929 to 2002 against
the natural logs of the aforementioned right- hand- side variables. For the
relationship to be robust the estimated coefficients need to be opposite in
sign and statistically significant.
The empirical evidence in favour of a Kuznets relationship in the field
of long- run steel intensity in the United States is strong. Not only are the
coefficients correctly signed and significant at the 1 per cent level, but also
the adjusted fit of the model is surprisingly high. We conduct the same test
with the raw data and get broadly similar results.
The results for all tests are presented in Appendix Tables 2.A1 and 2.A2
at the end of this chapter and here in Figures 2.1(a) and 2.1(b). For the

The existence of a KCS is consistent with the inferences of the synthe-

time, the literature on metal usage was divided into two distinct schools.
They were the consumer preference school that pioneered intensity of

20 The Chinese steel industry’s transformation
use (IU) analysis, and the leapfrogging school. The consumer preference
school argued that IU (defined as the volume of metal consumed per unit
of output) increased in low income economies over time as demand for
durable goods created derived demand for metals (International Iron and
Steel Institute, 1972; Malenbaum, 1973, 1975). In this view of the world,
as economies transition towards developed status, the consumption basket
shifts progressively towards services such as health, education and recrea-
tion, at the expense of the eventually saturated metal- intensive durables
goods market. Thus the development of consumer preferences with rising
incomes creates an inverted U- shaped IU curve with a definable turning
point.
The leapfrogging school argued that the ability of low- income econ-
omies to skip whole generations of technologies gave a downward bias
to IU over time (Hwang and Tilton, 1990). Essentially, the leapfrogging
school argued that a low- income economy’s ability to import technology
could transplant it to the same point on the hypothesized IU schedule
as an advanced economy; or alternatively, they were able to navigate to
lower IU schedules relative to those that previous generations of industrial
countries had inhabited at equivalent income levels. The implication was
that a low- income economy was just as likely to see a decline in its IU as it
moved towards middle- income status, rather than see the rise assumed by
the consumer preferences school.
A synthesis was achieved by the work of Lohani and Tilton (1993).
They argued that there was partial truth in the teachings of both schools
that could be reconciled in a single theory by a relatively simple empirical
test. Building on the implications of Hwang and Tilton (1990), Lohani
and Tilton studied changes in the IU of a cross- section of low- income
economies between 1977 and 1988 to test both the extant theories and
the viability of a synthesis view. Their hypothesis was that IU in the low-
income economies was related linearly to both income per capita (change
in purchasing power and consumption patterns) and time (change in the
technological frontier). If the extreme version of the leapfrogging school
was correct then the coefficients derived from their cross- sectional regres-
sion should have been zero for income per capita, and negatively signed
for the time trend. If the extreme version of the consumer preferences
school was correct then the coefficients should have been zero for the time
trend and positively signed for income per capita. The synthesis would
see a positively signed coefficient for income per capita and a negatively
signed coefficient for the time trend.
The result was that the synthesis view carried the day. More specifically,
the authors indicated that a real income growth rate of approximately 1
per cent per annum was required to keep IU stable against the underlying
M3021 - SONG 978184844658 PRINT.indd 20M3021 - SONG 978184844658 PRINT.indd 20 23/11/2012 14:5123/11/2012 14:51

gravity of the leapfrogging phenomenon. Therefore, low- income countries
achieving strong rates of economic growth will see rising IU, but those
that are stagnating will see IU fall due to technological change, or others
factors that are captured by the time trend. The synthesis view is thus a
‘proto- KCS’.
A CAUTIONARY TALE FROM THE ARCHIVES
The finding that steel intensity in the United States during the twen-
tieth century has followed an upside- down U- shape indicates that the
Kuznets framework may be applicable to the entire metal intensity field.
Unfortunately, not all relevant countries offer time series as long as those
of the United States. That leaves many scholars to rely on cross- sections,
as Lohani and Tilton did in establishing the synthesis view. The cross-
sectional data offers corroborating, if tentative, evidence for the national
KCS of the United States. It is very tempting to use these apparent rela-
tionships to define a generalized path of metal intensity through the indus-
trialization process.
While tempting, the validity of such a methodology is highly debatable.
Kuznets’s original observation of the upside- down U in income per capita
and income distribution space (Kuznets, 1955), which became known as
the Kuznets curve, is actually an egregious example of cross- sectional
bias. Much as with our data on metal intensity, Kuznets had a patchy time
series of US income distribution (plus the United Kingdom and Germany/
Prussia/Saxony) and a cross- section of information from a few countries
at a spread of lower income levels.1 These economies provided the hump
in his hypothesized curve, ‘corroborating’ the patchy time- series evidence.
Subsequent experience of East Asian trajectories following their entry
into modern economic growth in the quarter- century following the Second
World War, where inequality was reduced between the low- and middle-
income stages of development, has shown that the Latin American and
South Asian paths observed by Kuznets are idiosyncratic rather than
general. Indeed, the Latin trajectory was an outgrowth of poor planning
decisions that ignored comparative advantage in favour of import substi-
tution (Lin, 2008). The dual impediments of caste and colonial overlord-
ship, which are redistributive strategies rather than surplus- enhancing
ones, seem sufficient to comprehend the South Asian case. These two
models encouraged the supernormal growth of a rent- seeking elite, with
predictable outcomes for income distribution. Therefore, the original
Kuznets curve is a cautionary tale for scholars of development looking to
cross- sectional data for predictive relationships.

22 The Chinese steel industry’s transformation
The hump in a steel intensity cross- section is provided by two medium-
sized middle- income North Asian economies – Korea and Taiwan prov-
ince. They are both relatively new entrants to industrialization, with their
engagement occurring within the last half- century. Are these economies
typical or atypical? This judgement could validate or invalidate the cross-
section as representative, as we do not have readily available alternatives
to substitute into the middle- income space. Most development economists
would choose the latter taxonomy (atypical) if they were judging the case
globally and the former (typical) if assessing the case regionally. This is a
vexed issue we will revisit in different contexts in this chapter.
To be fair to Kuznets, who was the consummate empirical economist of
his generation, he was
acutely conscious of the meagreness of the reliable information presented. The paper is perhaps 5 per cent empirical information and 95 per cent speculation, some of it possibly tainted by wishful thinking. The excuse for building an elaborate structure on such a shaky foundation is a deep interest in the subject and a wish to share it. The formal and no less genuine excuse is that the subject is central to much of economic analysis and thinking; that our knowledge of it is inadequate; that a more cogent view of the whole field may help channel our interests and work in intellectually profitable directions; that speculation is an effective way of presenting a broad view of the field; and that as long as it is recognized as a collection of hunches calling for further investigation rather than a set of fully tested conclusions, little harm and much good may result. (Kuznets 1955, p. 26)
It is easy to agree and to empathize with many of the sentiments
expressed in this disclaimer. Indeed, Kuznets might have been putting the
case for a wider research agenda on metal intensity in the current day,
such is the overlap between his case and ours. However, the final assertion
is somewhat problematic when the task at hand is a practical forecasting
project that might guide real- world decision- making.
A mixed example of the practical application of the Kuznets framework
is the innovative extension of the hypothesis into the environmental field
(Grossman and Kruger, 1995). This has been a lucrative and knowledge-
enhancing application. This branch includes a burgeoning literature on the
applicability of the ‘environmental Kuznets curve’ (Cai and Du, 2008; Bao et
al., 2008; Bao and Peng, 2006). Yet the debate has also highlighted the limita-
tions of the framework as a generalizable forecasting system, with national
deviations from the central model common and only certain measures of pol-
lution behaving in accordance with theory. That has not stopped some schol-
ars from adopting the framework as a crude argument in favour of a passive
approach to negative environmental externalities. It is extremely important
that the caveats presented here are recognized and understood.

Metal intensity in comparative historical perspective 23
AN ASIDE ON AUTOMOBILE PENETRATION: WHY TIME SERIES MATTER
While cross- sectional metal intensity data of recent vintage is available for
a wide variety of countries at various states of engagement with the strate-
gic transition, using these data alone has the potential to be highly mislead-
ing. A focus on comparative time- series data is crucial to define the path
from the genesis of industrialization to peak metal intensity to a mature
state. Cross- sections can help with this task, but they can easily mislead
rather than guide. The difficulty is that while a cross- section may be able
to define states of nature at the initiation and maturity of the process, the
path between these two states may be hidden, and the peak identified erro-
neously, if the sample is imperfect.
An instructive example of the potential problems associated with
cross- sectional data comes from the field of automobile penetration.
Contemporary data on the number of passenger cars per 1000 persons for
a wide variety of countries are readily available. In addition, there are time
series for the United States (from 1929) and Japan (from 1960). Ignoring
the two time series for a moment, the cross- sectional data implies that a
simple linear association exists between income per capita and automobile
penetration, with a clustering of observations in the lower left and upper
right corners of the chart space (Figure 2.2a).
The time series tell a far richer story (Figure 2.2(b)). They indicate that
the path between low and high automobile penetration can be dramati-
cally different. Once again, we find that a reliance on relationships inferred
solely from a cross- section would lead to damaging forecasting errors.
Japan is highly urbanized, densely populated and without a domestic oil
resource. The United States is moderately urbanized, reasonably sparsely
populated and it controls a great deal of oil. The Japanese were quite
rational to follow the path they did and the Americans likewise.
Here again, we are struck by the diversity of national experiences, rather
than their similarity. The ability to ascribe any economy as ‘typical’ seems
very limited. Once again, we find little guidance on the transition between
stages, with scant evidence from middle- income locales. Forecasters operat-
ing in the automobile penetration field have realized this, and are projecting
a non- linear, concave path for China (International Monetary Fund, 2005).
While the ultimate peak level of automobile penetration is certainly contest-
able given the environmental and congestion issues that come with height-
ened automobile use, these issues will be no more pronounced in Chinese
cities than in the ever denser populations of Hong Kong, Singapore, Korea
and Japan. Indeed, the levels of automobile penetration in Hong Kong and
Singapore might be seen as a lower boundary for the Chinese case.

24 The Chinese steel industry’s transformation
There is a very practical reason why we should be interested in the time
series on automobile penetration besides the aforementioned analogical
and methodological considerations. The evidence for a Kuznetsian rela-
tionship in the historical steel intensity of the United States is comfort-
ably sufficient when couched in the simplest of forms. However, when

data on automobile penetration are included in the test (in original form
and as a squared term) as additional information on the stage of devel-
opment, the model improves on all metrics by a non- trivial margin. Most
simply, the adjusted R2 (the ‘fit’) rises from 0.63 to 0.71 and the standard
error declines. (For estimation output, refer to Table 2.A3 in the appen-
dix.) Thus we can conclude that automobile penetration is an important
measure for assessing both the general stage of economic development and
the likely metal intensity of the economy.
These conclusions add to the complexity of the original task. The pres-
ence of a Kuznets relationship in the long- run steel intensity of the United
States offered some hope that a generalizable relationship between metal
demand and development level could be defined. The presence of a rela-
tionship between metal intensity and automobile penetration raises hopes
of an indirect test of the homogeneity of national paths, but as two major
countries have followed such strikingly disparate paths regarding auto-
mobile penetration, we cannot credibly infer or back- cast Japan’s metal
intensity path using the United States example.
OBSERVATIONS ON THE NORTH ASIAN PEER GROUP
The backbone of the comparative analysis of metal intensity within North
Asia is shown in Table 2.1. China, Japan and Korea are its subject. Per
capita consumption of steel, aluminium and copper (sourced from the
International Monetary Fund (IMF); units are kilograms) during their
respective take- off phases are benchmarked against macroeconomic vari-
ables that a priori are expected to have a relationship with metal intensity.
The macroeconomic variables chosen for the table are: gross domestic
product (GDP) per capita (under both purchasing power parity (PPP) and
market exchange rate weights); industrial value added (IVA) as a percent-
age of GDP; urban population as a share of total population; exports
of goods and services as a percentage of GDP; and trade (exports plus
imports) as a percentage of GDP; merchandise exports; percentage of
world exports; gross fixed capital formation (GFCF) as a percentage of
GDP; and gross savings as a percentage of GDP.
Keeping all of the caveats from the preceding sections of the chapter in
mind, the following points have emerged from an investigation of the data
available. They are all relevant to constructing an educated, if tentative,
guess about China’s future trajectory.
IVA tends to peak as a share of GDP between income levels of $US10 000
and 15 000 per capita in PPP terms, and then decline. That accords with

ment) of approximately $US13 000 in latecoming East Asian countries

outlier in the sample, with a high IVA share prior to its entry into modern
economic growth, a relic of the self- sufficiency ethic that underpinned the
pre- 1978 anti- strategic economy, and the price distortions that went along
with the industrial bias of the command system.

30 The Chinese steel industry’s transformation
In contrast to the historical record on IVA, urbanization tends to keep
increasing well past middle- income levels. It also tends to plateau rather
than decline. That is almost certainly due to the fact that IVA loses ground
to services activity, which thrives on agglomeration, rather than land-
intensive endeavours, which do not. In short, while a nation can develop
to a post- industrial state, under the technological paradigm it does not
develop to a post- urban state. Rather, it concentrates its population
further. History is littered with evidence that the optimal city size increases
with the institutional complexity that lags the strategic demands generated
by technological change (Snooks, 1997).
The degree of outward orientation and metal intensity are positively
related. The most metal- intensive economy in the sample, Korea, is a
middle- income, export- oriented manufacturer. It is also highly urbanized
and has extremely high population density. Neither a plateau in its urban-
ization rate and IVA share, nor a decline in its investment and savings
rates, has handicapped its ability to raise metal intensity beyond the usual
turning point between $10 000 and $15 000 per head. Its ability to continue
gaining global market share beyond these points has enabled metal inten-
sity to continue rising. Brazil, a low- income economy with a weak outward
orientation, is the counterpoint.
China’s metal intensity was relatively insensitive to the very early stages
of industrialization and gains in export share. In the current decade,
though, metal intensity has become substantially more sensitive to devel-
opment, catching and surpassing the comparable Japanese and then
Korean rates. The low sensitivity seen in the early years is consistent with
the conventional light- to- heavy industrial path pursued by many new
latecomers. In Japan and Korea metal intensity grew extremely rapidly in
the 5–15 years from the take- off period, while the Chinese experience was
less dramatic. China’s surge comes in the 15–25- year era. This difference
may be partially attributable to the inadequacy of our time series, which
prevents the use of true global strategic transition (GST) entry points for
Japan and Korea.2
Copper and aluminium use have been more sensitive to the Asian indus-
trialization process than has steel use. This is perhaps due to the rapidly
increasing degree of openness that has been a feature of Asian industrial-
ization, and to the relative demands of the traded and non- traded sectors
vis- à- vis ferrous and non- ferrous metals. Ferrous metals have a lower
value- to- weight ratio than the non- ferrous complex and are therefore less
likely to be traded. Further, as an economy ascends the value chain, high-
value- added durable goods will displace heavy industrial products in the
output mix, raising the demand for non- ferrous vis- à- vis ferrous metals.
While rural–urban migration underpins demand for housing, infrastruc-
M3021 - SONG 978184844658 PRINT.indd 30M3021 - SONG 978184844658 PRINT.indd 30 23/11/2012 14:5123/11/2012 14:51

ture and steel, the demands of outward- oriented manufacturing appear to
be the stronger force at higher levels of income.
Bringing these observations together, we can say that an economy might
be fairly said to be in a metal intensity sweet spot if the following is true:
it is actively engaged in industrialization, with strong strategic leadership
sponsoring technological progress; it is approaching the GDP per capita
level consistent with a peak in industry share; it is in the midst of an urban-
izing trend; it is moving up the manufacturing value chain; it is making
global market share gains and tapping into external economies of scale;
it is saving enough to rapidly build the capital stock without a binding
external financing constraint; it is reaching an age of fixed and rotating
capital stock where depreciation costs are non- trivial; it has a willingness
to increase population density and provide the requisite infrastructure to
do so; and it is moving to extend access to the key pillars of social and
economic infrastructure to all its citizens.
FOREIGN DIRECT INVESTMENT AND LONG- RUN CONSTRAINTS GLOBAL ON MARKET SHARE
China’s high degree of openness to foreign direct investment (FDI) con-
trasts with Japan but gels with Korea. China’s rapid gains in world export
market share have been primarily a function of the activities of foreign-
funded firms, particularly in the post- WTO- accession era (Figure 2.3).
Trade fragmentation, with China serving the role of ‘assembler of first
resort’, has amplified both the trend of foreign participation and the
growth of export market share (Athukorala and Yamashita, 2008). These
observations open up another difficult forecasting problem. Korea has
continued to expand its export market share almost uninterrupted and has
achieved extremely high rates of metal intensity.
China’s path of metal intensity to date is closest to the Korean experi-
ence. However, were inward FDI to stabilize or decline (or were another
region to assume ‘assembler of first resort’ status)3 then export market
share could presumably do likewise, at least until an alternative strategy
could be adopted (McKay, 2008). That would prevent China from follow-
ing the Korean path. Indigenous Korean firms have established themselves
as globally competitive innovators in a number of sectors such as electron-
ics and shipbuilding. Indigenous Chinese firms have yet to do so, and are
probably at least a decade away from establishing strong brand awareness
among non- Chinese consumers. This perspective on the Chinese develop-
ment path cautions against excessive reliance on the Korean example.
China’s ability to continue expanding its world export share will surely
M3021 - SONG 978184844658 PRINT.indd 31M3021 - SONG 978184844658 PRINT.indd 31 23/11/2012 14:5123/11/2012 14:51
32 The Chinese steel industry’s transformation
be constrained by its enormous absolute scale and the resistance of its large
trading partners. The strong penetration of Chinese- made imports is already
a major political issue in the United States. The bilateral trade position
is a rallying point for both sides of US politics and the exchange rate is a
lightning rod.4 The historical example of the angst created by the bilateral
balance between the US and Japan, and the USD/JPY exchange rate, is the
obvious precedent. Over the coming decade, the expected appreciation of
China’s nominal exchange rate, and a rise in the relative price level as admin-
istrative distortions are progressively removed (Huang and Tao, 2010) and
productivity catch- up continues, should appreciate the real exchange rate
and reduce the current level of cost competitiveness enjoyed by the export
sector.5 At some point, China will be unable to seriously expect to expand
its exports at a faster pace than aggregate world demand. Korea’s small size
offers it the luxury of continuing to follow a strategy led by export manufac-
turing at income levels far higher than a larger economy – let alone a meg-
astate like China (Snooks, 1997) – would find obstacles placed in its path.
China will clearly be constrained in its choices to some extent by the stra-
tegic activities of its competitors. The attitudes of governments to Chinese

purchases of mineral resources in their domains will eventually become as
important as access for Chinese exports is in the current phase. This area
has already become contentious, with a Chinese principal prevented from
purchasing an energy asset in the United States, and the presence of great
angst within Australia regarding direct inroads into the resource sector by
Chinese investors (Drysdale and Findlay, 2008).
DOES INTRANATIONAL CONVERGENCE HOLD THE KEY?
A provincial approach to the Chinese data on metal intensity has the
potential to eventually remedy the shortcomings of the national data
sets.6 The provincial data also tentatively support a Kuznets- style metal-
intensity path. It is eminently reasonable to assume that there is a high
level of relevant information content in the paths already traced by
China’s wealthier provinces that are most actively engaged with the indus-
trialization and openness strategy.
This field of endeavour is particularly promising, but it does rely to a
degree on the arguable assumption that China’s wealthiest provinces have
already defined a structural peak in metal intensities from which they
are declining. In other words, they are beyond the ‘turning point’7 of an
explicit, generalizable Chinese KCS. It may be that observed reductions in
the metal intensity of the Beijing and Shanghai economies are the begin-
ning of a transition to a more cyclically informed usage, and therefore may
represent local rather than absolute maxima. After all, income levels in
Beijing and Shanghai are still only a quarter of present US levels, implying
that they are hardly at a level of productivity consistent with membership
of the strategic core. The US experience of metal intensity makes this
point about local versus global maxima in a number of historic contexts.
High- amplitude cyclicality was the norm throughout the twentieth century
(Figure 2.1(a)).
It might also be argued that Shanghai and Beijing are atypical observa-
tions. If these top- tier cities are treated as outliers, then it creates problems
for the cross- sectional analysis, because without them the Kuznets rela-
tion is far from clear. If these cities are excluded, then it would be prudent
to wait for a broader selection of provinces to mature in their steel usage
before attempting to define a definitive turning point for an economy as
diverse as China’s.
The proclivity of high- income countries to maintain an elevated if
somewhat reduced metal consumption pattern well beyond the peak in
industrialization implies that stock effects become a progressively more
M3021 - SONG 978184844658 PRINT.indd 33M3021 - SONG 978184844658 PRINT.indd 33 23/11/2012 14:5123/11/2012 14:51
34 The Chinese steel industry’s transformation
significant determinant of metal demand. The analysis presented here
could therefore be augmented by data on relative capital stock, or levels of
flow investment which take account of the ongoing costs of depreciating
and replacing fixed and rotating capital. Further, the metal intensity of
fixed investment may rise as higher levels of technology are attained and
households demand more sophisticated products. House sizes increase
with income (raising ferrous input), they become more ‘wired’ (raising
non- ferrous input) and structurally sound (again raising ferrous input).
Deepening the social infrastructure stock brings initial demand for wiring
and piping and then ongoing maintenance requirements. It therefore
seems obvious that models of metal intensity that focus solely on flow
variables will be incomplete. Each of these arguments is relevant to the
provincial analysis of Chinese metal intensity, as well as the study of metal
intensity across countries.
WHITHER CHINA?
It remains to make an assessment of what the Chinese path of metal inten-
sity will look like. The reasoning of this chapter indicates that while China
may look like Korea at the time of writing, it is unlikely to do so at higher
income levels. The main constraint in this regard will be China’s inability
to follow an export- led strategy in the same way that Korea has done.
China’s continental landmass represents a major contrast with the
compact nature of either the Japanese archipelago or the Korean penin-
sula. The United States is a far better comparison in this regard. The
United States’s effort to build an internal megamarket with a continental
transport system linking a multitude of metropolitan nodes tallies well
with China’s existing plans to expand interprovincial commerce via the
construction of an ambitious national road and rail network.
The density of population in China is far higher than in the United
States at any point in its history. Therefore, while China will have a
national intercity transport network similar to that of the United States,
intracity transit systems will presumably develop very differently. China
is therefore less likely to develop cities characterized by suburban sprawl
that rely upon automobiles. Rather, it will borrow from Japanese and
European models of mass public transit. One study (McKinsey Global
Institute, 2008) estimates that China will construct 170 mass transit
systems by 2025, servicing the majority of a projected 221 urban agglom-
erations with populations in excess of 1 million people. This projected
style of urbanization reinforces the assessment that China’s future path of
automobile penetration will not resemble that of the United States.

Metal intensity in comparative historical perspective 35
China’s ongoing urbanization drive is proceeding on a scale that does
not have a precedent. The westward expansion of the population of the
United States (Snooks, 1997, chapter 12), or the mass Siberian migration
of European Russians (ibid., pp. 442–6), is a tempting but not terribly
productive analogy. These two historical examples were based around
physical resource acquisition and exploitation. In China’s case, labour is
moving to expedite the industrialization strategy, not to exploit untapped
physical resources. The combination of immense scale and a distinct stra-
tegic underpinning argue that this particular factor must be considered on
its own merit without the benefit of firm historical guidance.
The aforementioned factors – external saturation, internal integration,
mass urbanization and urban style (alongside an anticipated path for
income per capita) – must guide our medium- term judgement. The United
States is a reasonable comparison in some cases, Japan in others. At times,
though, China’s uniqueness shines like a beacon.
Some milestones and relevant trajectories can be defined to give some
idea of the timing of the peak in Chinese metal intensity. China should
reach the $13 000 per capita income level around 2015, if it continues to
expand at the rates projected by growth accountants, and the demog-
raphers at the United Nations have done their sums correctly (Perkins
and Rawski, 2007; Wang, 2007; Garnaut et al., 2008; He et al., 2007;
United Nations, 2007). Given that its distance from the strategic leader-
ship will still be substantial at this point (around 20 per cent of US GDP
per capita), a relative level well below that at which other East Asian
countries began to experience decelerating growth (Garnaut et al., 2008),
we might reasonably consider 2015 as the earliest possible time that per
capita growth would begin to decline. Indeed, we note that the ‘turning
point’ in the general KCS represented by cross- sectional data, for what
it is worth, is around US$24 000 per capita. In the KCS estimated for the
United States, the turning point was around US$17 000 per capita. China
cannot be reasonably expected to reach either point any sooner than 2023
or 2019, respectively.
Further to those points, the five- year period 2015–20 is the turning
point for China’s demographic profile as projected by the United Nations
population division (United Nations, 2007).8 The momentum of urbani-
zation will also have calmed by this time, with 72 million rural to urban
migrants anticipated in the five years to 2020, down 10 per cent from the
estimated peak rate of the period 2005–10. By the five years to 2030, the
rate of urbanization will have declined by 38 per cent from peak rates, with
the urban share of the population surpassing 60 per cent, equivalent to the
global average.
The saturation point for the global economy regarding China’s exports is
M3021 - SONG 978184844658 PRINT.indd 35M3021 - SONG 978184844658 PRINT.indd 35 23/11/2012 14:5123/11/2012 14:51
36 The Chinese steel industry’s transformation
another core factor to consider. This was done in the previous section with
specific reference to differentiating China and Korea. Here we consider
the Japanese example. Japan’s export share grew in trend terms through
most of the Bretton Woods era, paused during the mid 1970s as energy
exporters reigned, and then continued its ascent all the way up to the Plaza
Accord of 1985. At this point Japanese GDP per capita had reached three-
quarters of the United States’s level (it would peak around 85 per cent in
1991); it had been the world’s second- largest economy for 16 years; and
the real exchange rate has more than doubled in value since the yen was
de- pegged from the US dollar. Further nominal and real yen appreciation
beyond 1985 resulted in a loss of competitiveness and precipitated a trend
decline in Japan’s export share in the second half of the 1980s. Japan also
had nowhere else to go from a sectoral perspective. By this stage Japanese
firms defined the technological frontier in many sectors. It became clear
that Japan could no longer seriously expect to sustain export growth faster
than the rate of growth in aggregate world trade. As its cost competitive-
ness eroded, increasingly it was unable to do even that. Japan’s externally
focused development strategy had been exhausted (McKay, 2008).
If these broad economic (as opposed to political) themes and relativities
need to be replicated in the Chinese instance before we reach the satura-
tion point for world export market share, then we are some way from
reaching such a peak. China will only reach two- fifths of US GDP per
capita levels by 2030, a level not far removed from the Japanese position
in the mid 1960s. Japan expanded its export share for two decades beyond
this landmark. Further, China’s real exchange rate has only just embarked
upon an appreciating trajectory. The economy has only recently exited a
protracted disinflationary period. Modest flexibility was introduced into
the nominal exchange rate regime in July 2005 (Golley and Tyers, 2007;
McKay, 2007). It seems unlikely that the level of the real exchange rate
will present a major hurdle for Chinese export market share gains for a
significant period of time.
China’s world export market share is approaching the levels at which
Japan’s share peaked, but while China is still increasing its share of world
output extremely rapidly, that growth accommodates a higher natural
share of global export trade. China is likely to become the largest economy
in the world, if not the richest. It will become far larger in relative terms
than Japan was when it achieved a 9 per cent share of world exports. As we
argued above, the growth in China’s export share will submit to gravity at
a GDP per capita level well below that currently prevailing in Korea, but
it will not face any time soon the economic hurdles that constrained Japan.
If we recognize that the politics of the situation are relevant, then it may be
that China will find that rapid global market share gains cease well ahead
M3021 - SONG 978184844658 PRINT.indd 36M3021 - SONG 978184844658 PRINT.indd 36 23/11/2012 14:5123/11/2012 14:51

of the schedule facing a ‘normal’ economy. Even a very pessimistic reading
of the situation would put that point deep into the 2010s, or possibly early
in the 2020s.
The United States increased its share of world merchandise exports
from around 3 per cent in 1800 to 9.8 per cent in 1860, 13.2 per cent by
1900 and 16 per cent in 19609 (Lipsey, 2000, p. 688, table 15.1). Clearly,
gains in world export share can continue for a very long time before the
global economy becomes saturated with the output of a nation that is itself
increasing its share of global output.
As discussed in this chapter, Chinese automobile penetration is antici-
pated to follow a path that is moderate by either Japanese or American
standards. The International Monetary Fund’s projections for automobile
ownership per thousand persons incorporate a 250 per cent expansion
between 2010 and 2020, and a 180 per cent rise between 2020 and 2030
(International Monetary Fund, 2005: 182). At 267 cars per 1000 people,
China would be less than half of the way to the saturation point observed
elsewhere. That implies that further automobile penetration beyond that
point would contribute to keeping Chinese metal intensity at a relatively
high level beyond the turning point.
The preceding discussion sketches a very broad range within which
various factors relevant to China’s intensity of steel use might peak: as
early as 2015 and as late as 2030. It seems fairly safe to trim this distribu-
tion at the near end. The idea of resource- intensive high growth decelerat-
ing as soon as 2015, at such low levels of relative income, relative capital
stock, in the midst of the urbanization drive and prior to the peak in
export market share, does not seem plausible. However, we might reason-
ably see the period 2015–20 as the likely moment when China conclusively
veers off the Korean trajectory and begins to define a more distinctive
individual path with a flatter gradient of increase.
If we allow China to follow Korea up to 2015, when we assume Chinese
income per capita has reached $13 000, then that would imply steel con-
sumption of 700 kg per capita, or 910 million tonnes. That is equivalent to
80 per cent of global steel output in 2005. A demand profile like that will
obviously put extreme pressure on global supply potential. It may encour-
age substitution decisions, and it may crowd out smaller consumers. In
sum, if China was to follow this path, other countries may have to review
their own strategies to cope, whether they are net importers or net export-
ers of resources.
The supply response to the strategic demands of the Chinese development
process will be critical to the final outcome. A strategic price signal, in the
form of the spectacular commodity price rises observed since 2003, is starkly
evident, so the incentive to invest is currently very large. The dominant
M3021 - SONG 978184844658 PRINT.indd 37M3021 - SONG 978184844658 PRINT.indd 37 23/11/2012 14:5123/11/2012 14:51
38 The Chinese steel industry’s transformation
players in supplying the market, the major global diversified resources com-
panies, are trumpeting their ability to meet huge projected Chinese demands
(Albanese, 2008; Kloppers, 2008). Taking that claim on board, while
simultaneously recognizing the unpredictable nature of the exploration
and discovery process and the oligopolistic nature of the industry, one sees
no reason to presume that excess supply of raw mate rials will emerge in a
sustainable fashion in ferrous metals markets. That will keep prices elevated
relative to historical norms and continue to drive the strategic demand for
future investment. Presuming the resource endowment exists then, we can
assume that China’s choices will not be curtailed by finite supply.
The period 2015–20 represents a transition phase in the projection, with
the structural drivers becoming more erratic and beginning to blend more
frequently with cyclical factors to determine metal demand. The precise
peak in Chinese steel usage per capita would thus occur somewhere within a
few years of 2020, with the distribution of likely outcomes skewed towards
the later dates in this range. Also, the use of ferrous scrap inputs to the steel
production process will be rising through this period, albeit from a very low
base, implying that China’s call on iron ore will be lower per unit of finished
steel. China’s low usage of scrap vis- à- vis steel producers in developed
countries, combined with the rapid increase in China’s share of finished
steel output, has raised the global ratio between steel output and iron ore
input. That has pushed iron ore prices higher than they would have been
otherwise. While this point is not integral to the central projection, it is a
matter of great importance for the iron- ore- producing community.
Importantly, it must be acknowledged that demand would become sig-
nificantly more volatile around the turning point. The experience of the
United States highlights that once cyclical factors become a material deter-
minant of per capita steel usage, the path of annual observations describes
a violent saw- tooth pattern. The gradient of the underlying trend is likely
to flatten appreciably once China moves assertively away from the Korean
course. It may even flatten absolutely. This seems more likely than a trend
of swift erosion in the intensity of steel usage on the far side of the turning
point. Given that the broad range initially defined stretched all the way
out to 2030, and the huge uncertainties at play, a hedging forecast allows
for a flat trend for a time following the tentatively defined peak.
CONCLUSIONS
Attempting to sketch China’s future path of metal intensity is not possible
without first assessing its overall strategic attitudes towards a multitude of
issues, both domestic and international.

Metal intensity in comparative historical perspective 39
The data presented in this chapter offer a broad range of perspectives
on the change in metal intensity at various distances from take- off. Some
tentative generalizations have emerged, as have some important findings
for individual countries. However, there are shortcomings in using either
the general- to- specific or the specific- to- general approach in a forecasting
framework.
As for China’s future path of metal intensity, it seems unlikely that it
will continue to resemble Korea’s beyond 2015 or so. The post- 2015 trajec-
tory will feature certain aspects that are reminiscent of the paths taken by
the United States and Japan, but the final outcome will not fully resem-
ble either. As a tentative and preliminary judgement, and assuming that
resource limits are not reached, the peak in Chinese steel usage per capita
is likely to occur at a point not too distant from 2020: possibly sooner,
but more likely later. The peak level of steel intensity will be well below
Korean levels of consumption, but close enough to Japan’s peak rate. It
is suggested that this peak will be sustained through the early and middle
2020s, before declining towards the end of the decade. Among all the
moving parts, the principal factor in deciding upon this long, flattish peak
is the current ‘under- urbanization’ of China relative to its development
level.
NOTES
1. Kuznets used data from India (1949/50), Ceylon (now Sri Lanka, 1950) and Puerto Rico (1948).
2. While an entry point for Korea in the early to middle 1960s is uncontroversial, Japan is a different case. Japan’s economic exploits prior to the Second World War are often discounted by non- specialists, but its industrial complex was strong enough to furnish a military force capable of defeating a European power (Russia) in a land and naval war in 1904/05. A late 1800s entry point, two generations after the first tier of European industrializers, at 37 per cent of western- European GDP/capita levels (Maddison, 2003), would be quite reasonable. This is a debate for another day, but it underscores once again that the available data fall well short of the worthy task at hand.
3. India, with its formidable labour supply profile, is the most commonly cited candidate for this role. A more likely outcome is that a group of competing low- income, labour- surplus economies will eventually displace China. In addition to India, long- run Asian candidates include Pakistan, Bangladesh, Indonesia, Vietnam and possibly emerging strategic states in North Korea and Myanmar. In 2050, the combined population of these countries excluding India is expected to be 1.1 billion (United Nations, 2007).

3. Economic growth, regional disparities and core steel demand in China
Jane Golley, Yu Sheng and Yuchun Zheng
INTRODUCTION
Two of the processes underpinning China’s economic growth and devel-
opment during the three decades between 1978 and 2008 have been
industrialization and urbanization. As one of the key inputs into these
two processes, Chinese crude steel demand has been strong throughout
this period, outstripping domestic production and making China a net
importer through to 2006. Domestic consumption is the key determi-
nant of domestic production and, with China being the largest steel
producer in the world at the time of writing, this makes understand-
ing future trends in Chinese steel demand a matter of both national
and global importance. Although we have the benefit of hindsight with
regard to the relationship between economic growth and steel demand
for a number of advanced economies, such as the United States, Japan
and South Korea, it is unclear which of these relationships, if any,
is likely to be most relevant to understanding that relationship for
China.1 Indeed, it is most likely that China’s path will be unique because
of a range of specific characteristics that are simply not replicated
elsewhere.
As an alternative to using the experience of other countries to under-
stand the future trajectory of Chinese steel demand, provincial- level
analysis offers a fruitful line of research. While there are certainly some
other provincial- level characteristics that are likely to make future tra-
jectories for steel demand differ across provinces, just as they do across
countries, it seems reasonable to assume that China’s less- developed
provinces are more likely to replicate the past trends of its leading
provinces than those of countries elsewhere. With the use of time- series
data, moreover, we are able to overcome the problems of cross- sectional
analysis pointed out by Huw McKay in Chapter 2, in order to clarify the
M3021 - SONG 978184844658 PRINT.indd 45M3021 - SONG 978184844658 PRINT.indd 45 23/11/2012 14:5123/11/2012 14:51
46 The Chinese steel industry’s transformation
driving forces behind dynamic trends in provincial- level steel demand
in the Chinese economy. In particular, we utilize the fact that there are
significant disparities in the levels of industrialization, urbanization
and per capita fixed- asset investment across China’s 31 provinces and
independent administrative metropolitan cities in order to address three
key questions. First, how can we address the provincial- level demand
for crude steel, given the absence of accurate, available data? Second,
what is the relationship between per capita income and the provincial
demand for crude steel per capita in China? Third, how do provincial
disparities in economic development impact on China’s total demand
for crude steel?
INDUSTRIALIZATION, URBANIZATION AND ECONOMIC GROWTH: IMPLICATIONS FOR REGIONAL DISPARITIES IN CHINA
In his seminal work on modern economic development, Simon Kuznets
(1965) identified industrialization as the central feature of the interrelated
set of structural transformation processes that accompany economic
growth.2 From an agricultural society to a modern industrial society,
the industrialization process is characterized by a number of common
features, including the following: an increase in the share of value- added
output created by secondary industry (mining, manufacturing and con-
struction, but particularly manufacturing) and a consequent fall in the
share of output created by primary industry (agriculture, forestry and
fisheries); an improvement in the technology base and the formation of an
integrated industrial system; rising levels of rural–urban migration and a
consequent increase in the urbanization rate; the establishment of tertiary
industry (services) and a rise in its contribution to national output; and
increasing per capita GDP.
While these features are common to the industrialization experience of
virtually all countries, the pace and extent of change varies substantially
from country to country and from era to era. One of the reasons behind
these cross- country growth differentials is that late- industrializing coun-
tries have been able to receive help from advanced countries in terms
of investment funding, technology and market access. Another notable
feature is that economic growth rates decline towards the end of the indus-
trialization phase – for example, most of the early industrializers expe-
rienced slower growth rates in 1973–98 than in 1950–73. Thus, Japan’s
growth slowed from the 1970s onwards, Singapore’s from the 1980s and
Korea’s from the late 1990s.3
M3021 - SONG 978184844658 PRINT.indd 46M3021 - SONG 978184844658 PRINT.indd 46 23/11/2012 14:5123/11/2012 14:51
Economic growth, regional disparity and core demand 47
The manufacturing sector is the key supporter of high- speed growth
during the industrialization process, although each country will clearly
have quite different industrial structures both within manufacturing and
across all industrial sectors. Meanwhile, the agricultural population is
a key limiting factor during the process of industrialization, with the
speed of industrialization being impacted not only by population size
but also by factors affecting the speed at which rural–urban migration
can unfold. China’s hukou system and its vast population suggest, for
example, that the process for the country on the whole will take longer
than in a country with a small population and no restrictions on popula-
tion movements. This has been evident in China’s urbanization process
during the past two decades. While over 150 million people have moved
from rural to urban areas since the late 1970s, the share of the popula-
tion living in urban areas had reached just 46 per cent in 2006, which is
well below the urbanization level for countries with China’s level of per
capita income according to the Chenery–Syrquin (1975) standard. Zhao
and Zhang (2008) note that in addition to the hukou system, low levels
of per capita natural resources have also restrained the pace of urbaniz-
ation in China.
Chenery et al. (1986) analysed a wide range of data from 137 coun-
tries, including income per capita, industry structure and urbanization
rates. This enabled them to divide industrialization into six stages,
summarized in Table 3.1.4 These stages reflect an extremely broad
spectrum of economic development, as suggested by the fact that Haiti,
Indonesia, Brazil, Poland, South Korea and Luxembourg fall into
stages 1 to 6, respectively. Table 3.2 lists GDP per capita, the proportion
of output produced by primary, secondary and tertiary industries, and
the urbanization rate for each of China’s provinces in 2006. According
to the national average (in the bottom row), China’s per capita GDP of
US$2214 in 2006, its urbanization rate of 44 per cent and its primary
share of output of 12 per cent suggest that it is somewhere between
stages 2 and 3.5 However, its share of secondary industry is higher than
any country in the entire range, while its share of tertiary industry places
it in stage 1. The inability to place China clearly in any one of these cat-
egories is indicative that using international experience to understand
China’s development path can be problematic. The task remains prob-
lematic at the provincial level as well, but for illustrative purposes an
attempt at allocating the provinces across the six industrialization stages
is made in Table 3.3, indicating that China’s provinces range from stage
1, or pre- industrialization, to stage 4, the last stage of industrialization.
A common deviation for all provinces from the standard pattern in
Table 3.1 is that provincial shares of tertiary industry are relatively low

Economic growth, regional disparity and core demand 49
while shares of secondary industry are relatively high. This may be one
reason why China’s steel demand is and may remain on a higher trajec-
tory than other countries, given that secondary industry is relatively
steel- intensive.

STEEL CONSUMPTION AND ECONOMIC GROWTH: A PROVINCIAL- LEVEL ANALYSIS
Traditionally, stable long- run economic growth was considered a suf-
ficient condition for stable long- run metal demand growth, through its
ongoing impact on metal- intensive sectors such as capital equipment,
transport and consumer durables. However, in the early 1970s, many
developed economies experienced a permanent slowdown in metals con-
sumption growth, despite continued economic growth overall.6 This gave
rise to the notion of an inverted- U- shaped long- term relationship between
GDP growth and metal consumption growth, or equivalently between per
capita GDP and per capita metal consumption. This relationship emerges
as a consequence of economic growth and development, two major com-
ponents of which are industrialization and urbanization. At low levels
of per capita GDP – that is, in the pre- industrialization stage described
above – national output is concentrated largely in primary industry,
which is characterized by relatively low per capita metal consumption. As
per capita GDP rises and the economy enters the industrialization stage,
changing consumer preferences drive a gradual shift towards more metal-
intensive products, including infrastructure and housing construction,
manufacturing, consumer durables and capital equipment. Urbanization
rates rise significantly during this stage as well, underpinning much of the
change in consumer preferences and production structure. During this
stage, metal consumption growth exceeds GDP growth and so per capita
metal consumption increases. In the post- industrialization stage, while
per capita income continues to rise, urbanization rates tend to plateau

Economic growth, regional disparity and core demand 51
and this, combined with the ongoing shift towards non- metal- intensive
services and high- technology products, drives per capita metal consump-
tion down.
Historical data for the early industrializers illustrate the idea of an
inverted- U- shaped relationship between steel consumption per capita
and per capita income, although it is clear that the relationship varies
over time and place. In 1974 the United States reached a peak of steel
consumption per capita of 674 kg with GDP per capita of US$20 050.7
Steel consumption per capita remained above 500 kg until 1980, and
then fell as low as 293 kg in 1982, thereafter fluctuating between that
level and 434 kg. Japan peaked in the same year as the US but with a
higher per capita steel consumption of 717 kg and a lower GDP per
capita of US$14 170. In 1970 the UK reached its peak steel consump-
tion at a lower per capita steel consumption than the US with a lower
per capita income, while Germany’s peak steel consumption was higher
and occurred at a lower per capita income level. In contrast, steel con-
sumption per capita in South Korea and Brazil, so- called newly indus-
trializing economies, has not yet revealed any downturn at the time of
writing. By 2004, South Korea’s crude steel consumption per capita
reached 981 kg, more than ten times the level in 1974. During this period
per capita income increased fivefold to reach US$18 840 – close to the
turning point for the United States but well beyond Japan’s. By 2005
Taiwan’s per capita steel consumption of 870 kg was higher than any
of the early industrializers’ peak levels, as was its per capita income of
US$21 446.
In line with the substantial differences in terms of economic develop-
ment among China’s provinces, there are also enormous differences in
crude steel consumption per capita, as illustrated in Figure 3.1. Shanghai’s
apparent crude steel consumption per capita of 769 kg in 2006 was 6.7
times higher than Guizhou’s mere 114 kg per capita. GDP per capita in
Shanghai was 9.4 times higher than in Guizhou. While Shanghai’s per
capita consumption was already past the peak of both the UK’s and the
United States’, its per capita income was not nearly as high as either one
was at the turning point. On average, it is even more obvious that China’s
provinces have not yet entered the post- industrialization stage referred
to in Table 3.2, and it seems very unlikely that the country on the whole
is even close to its own turning point, regardless of the corresponding
values of steel consumption and income for other countries. That is not
to say that a turning point will not emerge in the future, as the subsequent
analysis reveals.

ESTIMATING THE PROVINCIAL- LEVEL CORE DEMAND FOR CRUDE STEEL, 1979–2004
Although the relationship between per capita steel consumption and per
capita GDP at the provincial level can provide useful information on pro-
jecting Chinese total demand for crude steel, few studies have been carried
out owing to the data problems related to steel consumption at the provincial
level. The problems associated with using the official reported data on appar-
ent steel consumption are at least twofold. First, the data go back only as far
as the early 1990s, which is problematic in terms of the panel data estima-
tion techniques that are most appropriate for dealing with the issue at hand
– namely, long- term dynamics of Chinese steel demand. More crucially,
apparent crude steel demand for each province is calculated from official sta-
tistics simply by subtracting exports from total crude steel production. This
method is problematic because it does not consider inter- provincial trade
of crude steel owing to data availability, and so estimating consumption
will be biased by production data that are affected by central planning and
government preference (via state ownership of large steel enterprises). For

Economic growth, regional disparity and core demand 53
example, in Figure 3.1 above the apparent consumption of crude steel per
capita of Inner Mongolia was more than Liaoning’s and Shandong’s while
Ningxia’s was more than Jilin’s and Anhui’s. These figures are unconvincing
and reflect the high concentration of state- owned steel production in Inner
Mongolia and Ningxia rather than high consumption. Failure to deal with
this problem may lead to pseudo- regressions if GDP per capita is also cor-
related with steel production at the provincial level.
In order to deal with these problems, we propose an econometric
method for estimating core provincial- level steel consumption or under-
lying provincial- level steel demand by using information on industri-
alization, urbanization and the fixed- asset investments that result from
economic growth.8 Henceforth, we use the terms ‘core’ and ‘underlying’
interchangeably. Specifically, we estimate provincial demand for crude
steel between 1978 and 2004 by regressing steel production on measures
of industrialization, urbanization and fixed assets investment per capita.
We can do so for two reasons. First, owing to the fact that steel’s low-
value- added status makes it unprofitable for long- distance transportation,
crude steel production at the provincial level captures crucial information
about crude steel consumption at the provincial level.9 Second, given that
industrialization, urbanization and fixed- asset investment are demand-
related factors that are largely independent of supply, they can be used
as instruments for separating crude steel consumption from production.
This method enables us to construct time- series data that more accurately
reflect the underlying pattern of crude steel consumption across provinces.
Equation (3.1) specifies the regression model that is used for our first-
stage estimation:
ln (ProdSteelit) 5 b0 1 b1Industrializationit 1 b2Urbanizationit
1 b3 ln (FixedAssetInvit) 1 ui 1 eit, (3.1)
where ProdSteelit is the output of crude steel per capita in province i at
time t; Industrializationit, Urbanizationit and FixedAssetInvit are an indus-
trialization index (namely, the share of secondary and tertiary industry in
total output value), the urban share of the population and the amount of
fixed- asset investment per capita at 2000 constant prices; and ui represents
the time- invariant specific effects of each province. bn represents the coef-
ficient to be estimated and eit is the residual.
Data are drawn from a variety of sources. The production of crude steel
by provinces is available for 26 provinces between 1979 and 2004 in various
issues of the China Iron and Steel Statistical Yearbook.10 The industrializa-
tion index, urban population shares and fixed- asset investment ratios are

54 The Chinese steel industry’s transformation
also available for the same 26 provinces, and the same time period, in
China Comprehensive Data Collection 55 Years: 1949–2004 (CNBS, 2010).
To eliminate province- specific and time- specific effects, we adopt the
panel data regression technique with random effects to estimate Equation
(3.1), with the results presented in Table 3.4.11 From this table, it is clear
that industrialization, urbanization and fixed- asset investments each play
an important role in affecting the demand for crude steel, since their coef-
ficients are all positive and significant at the 1 per cent level.
Combining the estimated coefficients of the industrialization index, the
urbanization index and the fixed- asset investment index with their cor-
responding real value, we can generate the underlying demand for crude
steel per capita at the provincial level from 1979 to 2004:
ln(DSteelˆit) 5 b1Industrializationit 1 b2Urbanizationit
1 b3 ln (FixedAssetInvit) , (3.2)
where DSteelˆit is the predicted underlying demand for crude steel per
capita in province i at time t. The average estimated core demand level
for each year is presented in Table 3.5 and Figure 3.2, while Table 3.6 and
Figure 3.3 give the estimated consumption for each province in 2004. There

Economic growth, regional disparity and core demand 55
are three significant features worth highlighting. First, China’s period of
rapid economic growth has been accompanied by a rising average core
demand for crude steel, from 30 kg per person in 1979 to 159 kg in 2003.12
Second, there are significant regional disparities across regions in core
demand for crude steel, ranging from 234 kg per capita in Shanghai to just
64 kg per capita in Guizhou in 2004. Third, the consumption of crude steel
per capita appears to be (unsurprisingly) higher in the eastern region than
in the central and western regions, a point to which we return below.

ent consumption) across provinces in 2004. As the table shows, the pat-
terns of two data series are quite different. There are numerous reasons for
this divergence. First, the output of crude steel per capita – i.e. the depend-
ent variable in Equation (3.1) – clearly contains information from the
production perspective that is not captured by the demand- related factors
in the regression, including province- specific and time- specific supply- side

consumption to the extent that the independent variables in Equation (3.1)
are not the sole determinants of provincial demand. Third, disparities in
exports across provinces will account for some of the divergence between
total output and core demand (Liu et al., 2008). Critically, however, the
reasons for the divergence between our consumption estimates and the
actual production are not relevant to our key research question. What
is important to note is that our methodology here yields time- series data
that reflect the three dominant factors which not only determine steel con-
sumption in China but are also key factors in the economic development

process that we are attempting to connect to that steel consumption.
Moreover, the methodology reduces the impact of the supply- side prob-
lems mentioned above. For example, as shown in Figure 3.2, Inner
Mongolia, Ningxia and Hebei, which have relatively high output of crude
steel due to their large- scale planned steel industries, have relatively low
per capita core consumption using our methodology.
DISPARITIES IN ECONOMIC DEVELOPMENT AND CRUDE STEEL DEMAND PER CAPITA
We use the provincial estimates detailed above to analyse the relation-
ship between the core demand for crude steel per capita and the level of
regional economic development. The basic model is based on a Kuznets-
curve function, where the demand for crude steel per capita is determined
by income per capita as shown in Equation (3.3):
ln (DSteelˆit) 5 g0 1 g1
[ln (GDPit)] 1 g2
[ln (GDPit) ]2 1 uit, (3.3)
where ln (DSteelˆit) is the logarithm of estimated crude steel consumption
per capita, and GDPit is provincial GDP per capita. To capture the pos-
sible non- linear relationship between crude steel demand and income per
capita, a squared term of ln (GDPit) is also included. g0 is the constant
and uit is the residual.
Although pooled ordinary least squares (OLS) can be used to estimate
Equation (3.3), it has been criticized for giving rise to two econometric
problems. First, there is the omitted variable problem. In addition to
provincial economic development, there are many other factors that may
affect provincial- level core demand for crude steel, such as provincially
varying government policies and history. If these factors are positively
(negatively) correlated to the level of GDP per capita, then the estimated
coefficients on these variables will be overestimated (or underestimated).
Second, there is a potential mis- specification problem. Core crude steel
demand in China may be related to many unobserved provincial char-
acteristics, such as specific industrial structures and local fiscal policies.
Even if these characteristics are well controlled from the perspective of
omitted variables, we may encounter a fake inverted- U- shaped relation-
ship between crude steel consumption per capita and income per capita
when the data are pooled together. For example, Guangdong province
is dominated by light industry and thus its steel consumption level would
be lower than that of Liaoning where heavy industry is dominant, all
else being equal. If unaware of this problem, we would observe that
M3021 - SONG 978184844658 PRINT.indd 58M3021 - SONG 978184844658 PRINT.indd 58 23/11/2012 14:5123/11/2012 14:51
Economic growth, regional disparity and core demand 59
Guangdong’s higher per capita income is associated with lower steel
consumption – contributing to the downturn in the inverted U – when
lower steel consumption actually had more to do with the dominance of
light industry in Guangdong instead.
To deal with the omitted variable problem, we assume that there are
province- specific unobservable factors (that can be either time- invariant
or time- variant), and adopt the first- difference (FD) regression technique.
Although other methods such as the panel data regression with random
or fixed effects can also be used to solve the problem of omitted variables
from a theoretical perspective, the FD model is likely to be more appropri-
ate in this case, given that crude steel consumption as it relates to indus-
trialization and economic transition is more likely to be associated with
region- specific characteristics rather than changing frequently over time,
since it is a long- term issue (as in Chenery et al., 1986). We confirm that
this is the case using appropriate statistical tests13 and therefore opt for the
FD model, which results from rearranging Equation (3.3) as:
d ln (IndDSteelˆit) 5 g0 1 g1d [ln (GDPit
)] 1 g2d [ln (GDPit) ]2 1 uit, (3.4)
where uit represents latent variables which cannot be observed but are
related to core crude steel consumption. To deal with the mis- specification
problem, we test the model specification both with and without the square
term of GDP per capita, which confirms that the appropriate specification
does include the square term.14
The estimates for the pooled OLS and FD models are presented in Table
3.7. Columns (1) and (2) provide the estimated results from the pooled
OLS regression (adjusted for heteroscedasticity and provided for com-
parative purposes). While the estimated coefficients suggest an inverse-
U- shaped curve, they cannot be relied on for the reasons discussed above.
Thus, the FD regression technique is used instead and the results from this
regression are presented in columns (3) and (4). Based on the estimated
results from the FD model, the coefficient in front of GDP per capita and
its squared term are positive (2.613) and negative (−0.197), and both sig-
nificant at the 1 per cent level. This result, combined with the comparison
between the fitness of the specifications with and without the square term
of GDP per capita, demonstrates the existence of an inverse- U- shaped
relationship between GDP per capita and industrial demand for crude
steel per capita. The estimated turning point for the core demand for crude
steel at the provincial level on average in China is US$4728 at 2000 prices.
Although the above discussion provides some useful information on the
relationship between core crude steel consumption and GDP per capita at
the provincial level, the econometric results are valid only from an average

60 The Chinese steel industry’s transformation
perspective. To further identify the impact of regional disparities on the
relationship between crude steel consumption and GDP per capita, we
incorporate two dummy variables representing Eastern China (includ-
ing Beijing, Shanghai, Guangdong, Hebei, Jiangsu, Liaoning, Shandong,
Tianjin and Zhejiang) and Western China (including Gansu, Guizhou,
Ningxia, Qinghai, Shaanxi and Yunnan), respectively, which we interact
with GDP per capita. Our hypothesis is that if the relationship between
the core crude steel consumption per capita and GDP per capita are sig-
nificantly different across regions, these dummy variables and their inter-
action terms with GDP per capita will be statistically significant. In the
model specification, we incorporate both the solo dummy variables and
their interaction terms. However, the FD regression method eliminates the
former as they do not change over time. This means that we are unable to
ascertain whether there are differences in initial steel consumption across
provinces. The coefficients in front of the interaction terms capture the
difference in the marginal impacts of GDP per capita on the core crude
steel consumption per capita. Thus, Equation (3.4) can be rearranged as:
d ln (IndDSteelˆit) 5 g0 1 g1d [ln (GDPit

takes a value of 1 if the province is in the eastern region and 0 elsewhere.
Dummy_West takes a value of 1 if the province is in the western region and
0 elsewhere.
As expected, the relationship between the underlying demand for crude
steel and GDP per capita does indeed vary significantly across regions. As
shown in Table 3.8, the coefficient on the interaction between the regional
dummy and GDP per capita from the FD model is positive for the eastern
region and negative for the western region, and both coefficients are signifi-
cant at the 1 per cent level. This result implies that the marginal underly-
ing demand for crude steel is significantly higher in the eastern region and
lower in the western region, which results in different turning points across
regions. According to our estimates, the turning point for the eastern region
measured at 2000 constant prices is US$5400, compared with US$4728 and
US$4053 for the central and western regions, as shown in Figure 3.4.

62 The Chinese steel industry’s transformation
SIMULATING TRENDS IN CHINA’S NATIONAL CRUDE STEEL DEMAND
As Figure 3.4 illustrates, the relationship between per capita income and
per capita core steel consumption differs across regions. This implies that
the relationship at the national level will depend critically on the relative
income growth rates across provinces. Ignoring this is problematic in
terms of projecting China’s future aggregate demand for steel. To under-
stand how national- level trends will be affected by this range of disparities,
we use the estimates that determined the regional patterns in Figure 3.4 to
consider three hypothetical inter- regional growth scenarios.
Constant Growth Across Regions
If we assume that per capita income growth is the same across all regions,
say 8 per cent per annum, by applying this growth rate to each province
given initial income levels in 2004, we can determine how the regional and
national levels of per capita income will change over time. We then take
the per capita income level for each region in each year, beginning in 2005,
and use the regional estimates on the coefficients of per capita income and
its squared term to determine per capita core steel consumption for each

Economic growth, regional disparity and core demand 63
region. Then we take the weighted sum of these to determine national per
capita core steel consumption (where the weights reflect regional popu-
lations, which we assume will stay constant over time). This process is
repeated for each year through to 2020, with the aggregate projection illus-
trated in Figure 3.5. Even with constant income growth across regions,
what we expect and what we observe is a path that is quite different from
the national average projection depicted in Figure 3.5.
Convergence of Regional Per Capita Incomes (the ‘Effective Western
Development Strategy Scenario’)
In this case we assume instead that per capita income growth in the eastern
region stagnates – for simplicity, at zero per cent per annum – while the
western region records the most rapid growth at 8 per cent per annum and
the central region’s growth lies somewhere in between, at say 4 per cent per
annum. As Figure 3.5 shows, more rapid growth in the west generates a
much steeper trajectory and indicates that the aggregate turning point may
happen much later – that is, at a higher level of per capita income. This
result is intuitive given that the western provinces are much lower down on
their own curves and so are yet to experience much of the rise in per capita
steel consumption. Their rapid growth ensures that this rise happens
quickly. Simultaneously, slow (zero) growth in the east reduces the pace at

64 The Chinese steel industry’s transformation
which eastern provinces reach their own peak and hence extends the per
capita income aggregate turning point for declining per capita core steel
demand.
Ongoing Divergence of Regional Per Capita Incomes (the ‘Failed Western
Development Scenario’)
Here, we assume that per capita income growth in the eastern region
outpaces the rest of the country, at 8 per cent, compared with 4 per cent
for the centre and 0 per cent for the west. In contrast with the above sce-
narios, more rapid growth in the east precipitates an earlier aggregated
turning point, as these provinces are already further along their own curve.
Simultaneous, slower growth in the west dampens their contribution to the
upward trend in per capita steel consumption.
Given that there are an infinite number of possible combinations of
provincial growth rates in the future, it follows that the national aggregate
path of per capita steel consumption could essentially take on any kind
of shape in the next few decades – possibly but not necessarily reaching
the turning point, and possibly but not necessarily concave. How, then,
can our empirical analysis be used to understand China’s aggregate crude
steel demand? To demonstrate, consider the relationship between Chinese
demand for crude steel and GDP per capita at the national level in the
period since the late 1970s, a trajectory which shows an increasing trend
with no sign of a turning point (Figure 3.6(a)). One could attempt to make
use of these time- series data to predict the future demand for crude steel
consumption per capita, simply by extrapolating along the past trendline,
which is done in Figure 3.6(b). This trend seems to be inconsistent with
our previous discussion that the core crude steel demand per capita may
decrease as GDP per capita increases (in Figures 3.4 and 3.5). However, the
inconsistency can be easily explained if we consider the impact of regional
disparities and aggregation. In particular, were we to use the past rates of
growth of income across provinces in our model, the increasing trajectory
of crude steel demand per capita could be simulated.15 Similarly, fore-
casts of per capita income growth that take into account inter- provincial
growth disparities will provide a more accurate prediction for the future,
given that the aggregate- level relationship between crude steel consump-
tion per capita and GDP per capita as projected using past national- level
data (as in Figure 3.6(b)) does not provide any information regarding the
turning point for any province or for the nation on the whole.

CONCLUSIONS
Rapid economic growth and development since the late 1970s has her-
alded significant changes in the structure of the Chinese economy. China’s
underlying demand for crude steel has recorded strong growth as a result
of this structural change, and in particular as a result of the twin processes

66 The Chinese steel industry’s transformation
of industrialization and urbanization. Whether and when the consequent
rise in China’s per capita steel consumption will cease is a question of
importance not only for Chinese policy- makers and steel- makers, but for
all participants in the global steel market as well. Projecting future trends
in Chinese steel demand is complicated by the fact that China is charac-
terized by significant inequalities across its 31 provinces, many of which
are the size of large countries themselves, and further by the fact that
accurate time- series provincial- level data for steel demand are not readily
available.
The method adopted in this chapter has utilized provincial- level data
on steel production, in combination with three factors – the levels of
industrialization, urbanization and fixed- asset investment – to estimate a
time series of provincial- level core steel consumption or underlying steel
demand. We claim not that these estimates are precise, but rather that
they capture the dynamics of potential core steel consumption disparities
across regions (as determined by the major processes of structural change
that accompany ‘modern economic growth’). It is this component of per
capita core steel demand that is most likely to follow the Kuznetsian
inverted- U- shaped path as per capita income rises.
Armed with these provincial estimates, our econometric results con-
firmed that such a path exists at the provincial level in China. Given the
imprecision of our estimates, we attempted to provide a precise projection
neither of the future total demand for crude steel in China nor of when
the turning point for per capita steel demand might be reached. Instead,
we offered simulations to demonstrate that these potential estimates
would necessarily be influenced by the relative growth performances of
different provinces, because of the vast disparities in levels of develop-
ment across those provinces and hence their very different positions along
the predicted path. Failing to take these disparities into account risks
failing to understand just how dependent the future national- level trend
in Chinese steel demand will be on future patterns of inter- provincial
economic growth. We hope this chapter has provided a small step in the
right direction.

Germany and Chinese Taiwan comes from the International Iron and Steel Institute (2007). All per capita incomes reported are in 2000 prices.
8. Based on the above discussion, and also on Liu et al. (2008), there are three main factors affecting the per capita demand for crude steel in China: industrialization, urbanization and the fixed- asset investments that result from economic growth. The importance of the last of these three factors stems from the observation that levels of investment will increase as the industrial structure becomes more capital- intensive and as the demand for infrastructure associated with urbanization rises. While other factors, such as con-sumer preferences and the availability of substitutes for steel will also play a role in determining steel demand, Liu et al. (2008) estimate that the above three factors deter-mine between 60 and 70 per cent of crude steel consumption in China at the aggregate level and are largely representative of the demand- side perspective, which can be used to index changes in steel consumption.
9. See Chapter 5 on the point that the steel industry is not particularly well suited to export orientation, but rather that production tends to concentrate in countries where demand is high. Given that many – indeed most – of China’s provinces are themselves the size of large countries, this point carries over to the provincial level, suggesting that most provincial steel production will be consumed ‘domestically’, that is, within the province.
10. Sichuan (because Chongqing started to split in 1995), Fujian, Hainan and Tibet (the latter three have no complete data sets).
11. We also run a fixed- effect regression to test our model specification, and the Hausman test (used to test the null hypothesis that the fixed- effect model is not preferred to the random- effect model, is not rejected at the 10 per cent level) leads us to conclude that the estimates using the model with random effects are more accurate.
12. In 2004, macroeconomic adjustment policies from the central government reduced the industrialization, urbanization and fixed- asset investment measures for all provinces, which caused significant declines in their underlying demand for crude steel. This makes 2004 an outlier.
13. In particular, the Hausman test and the Breusch–Pagan test.14. If Guangdong’s lower per capita steel consumption had more to do with its industrial
structure than its higher level of per capita income, there would be no reason for Guangdong’s data to follow an inverted- U shape rather than a linear path. The fact that we find that the squared term is significant confirms that this is not an issue we need to worry about. We also run a random coefficient regression, which aims to identify the local curvature of the marginal contribution of per capita GDP to per capita steel consumption for each individual province. This confirms that the inclu-sion of the squared term is appropriate as all provinces follow an inverse- U- shaped trajectory.
15. This would take a substantial amount of effort as we would need information not only on provincial GDP growth rates across time but also on the simulated starting point for each province (which is not available because the FD regression eliminates the solo dummy variable), and so on. This is beyond the scope of this chapter, but the key point remains that the past combination of provincial growth rates should generate a trajec-tory that matches Figure 3.6, given that national steel demand is, by definition, the sum of provincial steel demand at any point in time.

4. China’s iron and steel industry performance: total factor productivity and its determinants
Yu Sheng and Ligang Song
INTRODUCTION
The rapid expansion of China’s iron and steel industry (hereafter ‘the
industry’) since early in the twenty- first century has been remarkable in
terms of both speed and scale. Yet there is an issue regarding the ‘quality’
of the industry’s expansion – was the rapid growth driven primarily by
increases in inputs or by gains in productivity? There is no consensus as to
which factors have been more important for driving the current wave of
the industrial expansion. However, a more sustainable and healthy devel-
opment of the industry should be based on the continuation of firm- level
productivity growth – a representation of both technological progress and
efficiency improvement. Examining the change of firm- level productivity
and its determinants over the past decade therefore becomes an important
empirical question.
There have been many attempts made to quantify the productivity of
China’s iron and steel firms and its determinants by using microeconomic
(firm- level) data. Jefferson (1990) was the first to estimate the total factor
productivity (TFP) of the industry by using a log–linear function with
cross- sectional data from 120 large and medium- sized enterprises (here-
after LMEs) in 1986. Kalirajan and Chao (1993) and Wu (1996) adopted
the stochastic frontier analysis to distinguish between firms’ technical
efficiency and their technological progress using cross- sectional and panel
data of LMEs before 2000, respectively. Zhang and Zhang (2001) exam-
ined the technical efficiency of China’s iron and steel firms in the 1990s
using data envelope analysis, and Ma et al. (2002) and Movshuk (2002)
focused on the ownership reform undertaken in the late 1990s and its
impact on firms’ TFP in the industry after 2000.
These studies have provided important insights into the changes of
firms’ productivity in the industry and its determinants in the past.

70 The Chinese steel industry’s transformation
However, their results proved quite diverse with respect to whether the
industry’s productivity and/or efficiency had increased or not over the
periods considered. For example, Zhang and Zhang (2001) found that
the average technical efficiency of China’s iron and steel firms had been
increasing in the 1990s, while Ma et al. (2002) and Movshuk (2002) found
to the contrary.
There are three possible explanations relating to both the methodology
and data issues for this inconsistency. The first is that studies estimat-
ing productivity via the stochastic frontier method (or the data envelope
analysis method) focus on technological efficiency by assuming that the
best- performing firms are at the production frontier. This assumption is
likely to generate results that are sensitive to sample choices. The second is
that LMEs (usually state- owned) were dominant across all samples (owing
to data availability). This means that some important information on
the prolific small- and- private- enterprise (hereafter SE) sector is excluded
from these studies. The third is that by utilizing data covering the period
from the late 1980s to the late 1990s, during which time many reforms in
the industry had not been fully implemented, or were yet to bear fruit,
these studies might therefore not have been able to capture more fully the
consequence of the reform. Thus it may not be surprising that the earlier
studies generated ambiguous results with respect to the impact of reform
on industry productivity.
This chapter seeks both to improve on the methods used in the previous
studies and to update the data set. We use some newly developed econo-
metric techniques to re- estimate Chinese iron and steel firms’ TFP by
using firm census data over the period 1998–2007. The approach adopted
here includes the Olley and Pakes (1996) and Levinsohn and Petrin (2003)
two- step method, and the generalized method of moment (GMM) method
proposed by Ackerberg et al. (2005) and Wooldridge (2009) to estimate
the industry’s production function with the gross output assumption.
These methods overcome the ‘endogeneity bias’ due to potential cor-
relation between capital usage and unobserved productivity (caused by
the assumption of exogenous inputs – capital – that plagues traditional
analysis) (Jefferson, 1990). As to the update of data, we believe that the
firm- level census data for the industry are the most recent data ever incor-
porated into a study of this type.
Three questions are to be addressed. First, how has firm- level pro-
ductivity in the industry changed over time? Second, what are the major
driving forces behind firm- level productivity growth in the industry over
the decade from 1998 to 2007? Third, are there any significant differences
in productivity growth among iron and steel firms with different char-
acteristics such as firm size, ownership type and geographical location?

Total factor productivity and its determinants 71
Answers to these questions show that productivities of firms of different
types in the Chinese iron and steel industry are not only different over the
period of 1998 to 2007, but also sensitive to different measures adopted
in carrying out the economic reforms in the industry. This implies that
further improvement in the productivity and quality of output of the
Chinese iron and steel industry may be enhanced by a range of policy
instruments targeting firms with different characteristics in the process of
restructuring the industry.
The remainder of the chapter is arranged as follows. The next section
describes briefly the development of China’s iron and steel industry
over the reform period. Some factors associated with changes in firms’
productivity in the industry, such as marketization reform, government-
sponsored investment and intensified competition, have been addressed.
The section that follows presents the model specification and the two- step
approach for estimating firms’ TFP and identifying its determinants. The
semi- parametric TFP estimation techniques and its related literature are
highlighted for their importance in dealing with the problem of ‘endoge-
neous input choice’. Data collection and summary statistics are presented
in the next section. The penultimate section discusses the estimation
results and the section after that concludes.
CHINA’S IRON AND STEEL INDUSTRY AND ITS MICROECONOMIC PERFORMANCE
While China’s iron and steel industry grew along with the rest of the
economy in the first decade of the reform era beginning in the late 1970s,
it was not until the early 1990s that the sector began to expand at a dra-
matic rate. During the period 1990–2007, China’s production of iron ore,
pig iron and crude steel has increased from 179 million tonnes (mt), 62 mt
and 66 mt to 582 mt, 404 mt and 422 mt, respectively, representing average
annual growth of 7.6 per cent, 12.4 per cent and 12.3 per cent. China’s
output of iron ore and crude steel rose to above one- third of the global
total, while its pig iron output rose to about half of world production.
The rapid expansion of output in the industry has been accompanied by
a significant industrial structural adjustment, characterized by a substan-
tial increase in the number of enterprises and an enlargement of scale at
individual firm level. The total number of firms in the industry increased
from 1589 in 1990 to 11 596 in 2007, while the average real output value
per firm (at 1990 constant prices) increased from US$17.2 million in 1990
to US$32.5 million in 2008.1 As a consequence, competition among firms
in the industry has been intensified and firms’ productivity has increased
M3021 - SONG 978184844658 PRINT.indd 71M3021 - SONG 978184844658 PRINT.indd 71 23/11/2012 14:5123/11/2012 14:51
72 The Chinese steel industry’s transformation
rapidly over time. Figure 4.1 shows the positive relationship between the
real output value of China’s iron and steel industry (at 1990 constant
prices) and its average labour productivity between 1985 and 2006.
There are three factors that seem most relevant for assessing the rapid
increase of firms’ productivity. First, marketization reforms rendered
more autonomy to enterprises (especially state- owned ones), thereby
helping to increase their production efficiency. Second, the rapid increase
in fixed investment and the associated boost to average production capac-
ity has helped to foster firm- level technological progress. Third, the free
entry of SEs (motivated by profit incentives) reduced LMEs’ market
power and intensified competition in the industry. We consider each of
these factors in turn.
First, the iron and steel industry in China has historically been domi-
nated by the large, integrated state- owned enterprises (hereafter SOEs). By
integrated enterprises, we mean the ferrous metals firms, which produce all
items across the spectrum from iron ore to finished steel, rather than those
which specialize in producing a single product. In 1990, there were a total
of 1589 iron and steel enterprises in China, among which 163 were state-
owned or state- controlled. In terms of output value, the SOEs accounted
for more than 80 per cent of the industry total. Given that the SOE struc-
ture imposed a heavy burden on these firms in the form of non- productive
spending such as housing, pensions and other welfare expenses, this pro-
vided scant executive incentive to pursue productivity gains. This is the
chief reason why the management efficiency of those enterprises was weak.

Total factor productivity and its determinants 73
Since the early 1990s, a series of microeconomic reform policies aiming
to promote the marketization of SOEs have been implemented. These
include the reform of the profit distribution system; the provision of
incentives for increasing productivity; reform of the management system;
market- based reform, especially with respect to pricing; introducing
foreign direct investment; and a free entry policy. The most recent reform
is what has been termed the ‘modern enterprises system’ and ‘shareholding
structure reform’, which began in the early 2000s and is still underway for
a few very large enterprises. These reforms make the SOEs more indepen-
dent of the government with respect to both financial arrangements and
managerial appointments. In 2006, the share of output volume accounted
for by SOEs had fallen to 43.1 per cent while the number of SOEs had
declined to 67 (accounting for 5.2 per cent of the total number of firms). As
a consequence of these changes, productivity and management efficiency
at firm level have been improved.
Second, the rapid increase of investment in new enterprises and the
accompanying technological changes has assisted productivity gains at the
firm level. The industry has been characterized historically by a mixture
of old and advanced production technologies, with the weighted average
level of technology lagging far behind the conditions in the industrialized
countries. In 1990, the average continuous casting ratio in China’s iron
and steel industry was only 22.2 per cent, which is far less than the ratio of
above 95 per cent in the other main steel- making countries. Around 15 per
cent of crude steel was still being produced in open- hearth furnaces (OHF)
in China, which have effectively been scrapped in most steel- producing
countries.
To catch up with the world leaders in producing steel, a very large
amount of capital has been invested in production technology since the
1990s. These investments have been jointly funded by the central and pro-
vincial governments and a considerable amount of investment has come
from SOEs themselves and private sources. Between 1990 and 2005, the
average annual fixed- assets investment in China’s iron and steel industry
increased from US$2.7 billion to US$31.5 billion yuan (the exchange
rate used for deflating the series comes from China Statistical Yearbook
(CNBS, 2009)). This massive increase in investment has substantially
improved the standard of the industry’s production technology. In 2005,
the average continuous casting ratio had increased to 94 per cent and
crude steel produced from basic oxygen furnaces (BOF) and electric
arc furnaces (EAF) accounted for 88.1 per cent and 11.7 per cent of the
total, respectively. Such rapid improvements in production technology
imply that there should be significant gains in firm and industry levels of
productivity.

74 The Chinese steel industry’s transformation
Third, the intensified competition due to free entry of SEs and its
associated reallocation of market share and resources within the industry
has favoured those with advanced production technology, promoting
productivity growth in the quest for profits. The industry is believed to
be one of the few sectors that can realistically expect increasing returns to
scale, given the large amount of sunk costs embedded in any steel enter-
prise. Thus, firms aiming to obtain higher productivity through increasing
returns to scale must seek to achieve both gains in market share and the
expansion of productive capacity, as well as securing additional access to
intermediate inputs including finance. With the increased number of firms
in the industry, the share of national crude steel production accounted for
by the top eight firms between 1998 and 2007 declined from 33 per cent to
17.9 per cent; the Herfindahl index of industrial concentration at the three-
digit level (defined as the squared share of the top eight firms’ market
sales revenue in the total revenue of the industry; see Brown and Warren-
Boulton, 1988) accordingly decreased from 33 in 1998 to 22.3 in 2007.
The discussions provide some background information on firm- level
productivity change and its potential drivers in the industry. The next step
is to detect the trend of the firm- level productivity and to identify the main
factors which determine the trend. In the following section, we start with
estimating firms’ TFP by using the newly developed endogeneous input
usage method.
MODEL SPECIFICATION: ENDOGENOUS INPUT USAGE AND FIRMS’ PRODUCTIVITY
Estimating productivity as a residual after accounting for measurable
inputs and then decomposing that TFP into its proximate determinants
is a long- standing preoccupation of empirical economists, going back to
the seminal paper by Solow (1957). While the Solow ‘growth account-
ing’ framework has been widely applied for carrying out economy- wide
analysis, the technique is easily adapted to microeconomic analysis. The
standard approach is to assume a Cobb–Douglas, quadratic or translog
production function with an additive, time- consistent firm effect and to
solve the unobserved endogeneity problem by using fixed- effect general
least squares (GLS) estimation. Unfortunately, the fixed- effect estimator
still assumes strict exogeneity of the inputs (that is, labour, capital and
various intermediate inputs), which is conditional on firms’ heterogeneity
in productivity (Wooldridge, 2002). This assumption requires that inputs
must not be chosen in response to productivity shocks – a severe and
unrealistic restriction on firm behaviour.
M3021 - SONG 978184844658 PRINT.indd 74M3021 - SONG 978184844658 PRINT.indd 74 23/11/2012 14:5123/11/2012 14:51
Total factor productivity and its determinants 75
To deal with this problem, econometricians have resorted to using
the instrumental variable method (say, using lagged inputs as instru-
ments for inputs) to relax the strict exogeneity assumption for inputs.
For example, Arellano and Bover (1995) and Blundell and Bond (2000)
use this approach to correct the estimation of their production functions.
Although this method works well in some cases, it is open to two criti-
cisms. The first is that introducing lags into the regression (or differenc-
ing) removes much of the variation in the explanatory variables and can
exacerbate the measurement error of the inputs. The other is that the
instruments available after differencing are often only weakly correlated
with the differenced explanatory variables.
Olley and Pakes (1996; hereafter OP) arrived at an alternative way
to deal with the endogenous input problem. Rather than allowing for
time- constant firm heterogeneity, OP show that, under certain assump-
tions, investment can be used as a proxy variable for unobserved, time-
varying productivity. In other words, productivity can be expressed as an
unknown function of capital and investment (when investment is strictly
positive). This, for the first time, took the simultaneity problem explicitly
into account when estimating a production function by introducing an
estimation algorithm. Following this innovation, Levinsohn and Petrin
(2003; hereafter LP) later proposed a modification of OP’s method to
address the problem of lumpy investment. They suggested the use of
intermediate inputs as a proxy for unobserved productivity, a method that
generated a better result than the use of an investment variable.
Generally, both the OP and LP methods suggest a two- step process to
consistently estimate the coefficients on variable inputs. In the first stage,
semi- parametric methods are used to estimate the coefficients on the vari-
able inputs along with the non- parametric function linking productivity to
capital and investment. In a second step, the parameters on capital inputs
can be identified under the assumptions on the dynamics of the produc-
tivity process. Both the OP and LP methodologies have been widely used
in the recent literature on firm- level heterogeneity for derivation of TFP
measures, though the LP method is more preferred to the OP method in
practice since it can save more observations when firms, as is common, do
not carry out long- term investment on an annual basis.
More recently, Ackerberg et al. (2008; hereafter ACF) argued that,
while there are some solid and intuitive identification ideas in the papers
by Olley and Pakes (1996) and Levinsohn and Petrin (2003), their two-
step semi- parametric techniques may suffer from a potential problem
with identification of parameter in the first- stage estimation – if all inputs
(including labour usage) are determined by a TFP shock (and thus opti-
mally chosen by the firm), then they all enter the deterministic function
M3021 - SONG 978184844658 PRINT.indd 75M3021 - SONG 978184844658 PRINT.indd 75 23/11/2012 14:5123/11/2012 14:51
76 The Chinese steel industry’s transformation
of unobserved productivity and stated variables. As a consequence,
the coefficient on the variable input is non- parametrically unidentified.
ACF showed that specifying popular functional forms for the produc-
tion process does not help. In fact, in the Cobb–Douglas case (and some
others), labour disappears after substituting unobserved productivity as a
function of inputs (Wooldridge, 2009). This problem is more serious for
the LP estimation since the potential collinearity between intermediate
inputs and labour is usually strong in practice.
To deal with this problem, ACF proposed a hybrid of the OP and LP
approaches, along with the assumptions on the timing of decisions concern-
ing input choice. Specifically, ACF resolved the potential lack of identifica-
tion by using a two- step estimation method that does not attempt to identify
any production parameters in the first stage. Later, Wooldridge (2009)
further extended the estimation method by using a unified GMM estima-
tion, which allows for the possibility that the first stage of OP or LP actually
contains identifying information for parameters on the variable inputs, such
as labour. Since the Wooldridge method is a one- step GMM procedure, it
can use the cross- equation correlation to enhance efficiency, and the optimal
weighting matrix efficiently accounts for serial correlation and heteroscedas-
ticity. Thus, the Wooldridge GMM method for production function estima-
tion is the most preferred regarding its consistency and effectiveness.
In this chapter, we use the Wooldridge GMM method to estimate firms’
TFP, while checking the robustness of our results by using the OP and LP
methods as well as some other traditional measures. For simplicity, we
assume that the production function of China’s iron and steel firms takes
the Cobb–Douglas form with endogenous capital and labour usage.2

DATA COLLECTION AND SUMMARY STATISTICS
The data used in this study are taken from the annual firm census carried
out by the National Bureau of Statistics (hereafter NBS) during the
period 1998–2007. The survey covers all enterprises above a designated
size (with annual sales reaching at least 5 million yuan) regardless of
ownership status. Iron and steel firms are defined as the firms registered
with the sector of ‘smelting and pressing of ferrous metals’ (namely, the
thirty- second category according to the two- digit Chinese Industrial
Classification Code). Discarding enterprises with incomplete data left
33 778 observations, which covered 1654 firms in 1998 to 4929 firms in
2007. These firms have accounted for more than 70 per cent of the total
number of enterprises in the industry and their combined output and asset
shares were around 90 per cent of the total. Table 4.1 shows a statistical
summary of these firms. Compared with data used in previous studies,
our sample is more representative, as it covers not only the LMEs owned
by the state but also a large number of SEs and private firms. This helps
reduce the selection bias significantly.
The output of iron and steel firms is defined as the total output value
discounted by the producer price index at the firm level. Our reasoning for
this choice of deflator is that the industry is composed of multiple types
of enterprise with different output structures. The vertically integrated
enterprises produce all of the products in the product chain, including iron
ore, metallurgical coke, pig iron, ferroalloys, refractories and finished steel
M3021 - SONG 978184844658 PRINT.indd 77M3021 - SONG 978184844658 PRINT.indd 77 23/11/2012 14:5123/11/2012 14:51

products. Others may produce only one or two items in the chain of iron
and steel production. From this perspective, output values are much better
than physical output as a means of comparison. All the output values are
benchmarked to the 1990 price level.
Capital usage is defined as the value of net fixed assets, which is equal
to total fixed assets less accumulated depreciation, deflated using the
fixed asset investment price index for the industry. Although it is argued
that net fixed assets provide a problematic measure of the total capital of
China’s iron and steel enterprises (Jefferson, 1990), there is little we can
do to adjust this due to data limitations at the firm level. Labour usage is
defined as the number of employees working in the industry at the end of
each calendar year rather than the total of all labour employed during the
course of the year. The reason for this is that there is a certain proportion
of employees who are not directly involved in productive activity in the
industry, especially in LMEs.3 In this study, we did not make distinctions
between skilled and unskilled workers, owing to lack of consistent data
over time.
Intermediate inputs are defined as the total output value (current price)
minus value added plus the value added tax, which is consistent with the
approach of the NBS. To eliminate the impact of inflation, a ‘single defla-

tion’ approach, which assumes identical deflators for all intermediate
materials and valued added, is used to adjust the impact of price changes
on the estimation of intermediate input quantity. In other words, a firm-
level ratio of real to nominal gross industrial output is calculated and used
to deflate the intermediate input values.
Finally, we define a series of variables that may reasonably be
expected to have impacted on firms’ productivity. They include: (1) the
Herfindahl index, defined as the squared share of the top eight firms’
sales revenue in the industry total at three- digit- level CICC sectors; (2)
an index for marketization, defined as the share of non- state- ownership
in firms’ real capital; (3) a R&D proxy index, defined as the share of
revenue from selling new products; (4) the scale indices, defined as
dummies distinguishing between small, medium and large firms; and (5)
firms’ export ratio, which is defined as the share of revenue from firms’
exports.
FIRM- LEVEL TFP ESTIMATION AND ITS DETERMINANTS
Table 4.2 reports the estimated production function coefficients for
China’s iron and steel enterprises obtained using different methodologies.
All reported estimates are obtained for the unbalanced panel data during
the period 1998–2007. Each column reports a set of estimators obtained
by using a specific method. The focus is principally on the column headed
GMM with other columns (in particular the OP and LP estimation) for
comparison.
The comparison between the estimated results obtained from using the
non- parametric methods (including OP, LP and GMM) with those from
the OLS, first- differencing and fixed- effects methods shows that coeffi-
cients obtained with the non- parametric methods are lower in magnitude
for both labour and intermediate inputs but higher for capital. In particu-
lar, the marginal contribution of capital is estimated to be significantly
larger than that of labour in the GMM estimation. This implies that
capital usage plays a more important role than labour in the production
of China’s iron and steel firms. This finding is consistent with the key
characteristic of this industry, which is its capital intensity. This also sug-
gests that the problem of ‘endogenous input usage’ applied in the previous
studies reviewed is likely to have caused an underestimation of capital’s
contribution and a corresponding overestimation of intermediate inputs’
contribution to output (noting that the coefficient assigned to labour input
is not changed significantly in GMM vis- à- vis OLS or the fixed- effects
M3021 - SONG 978184844658 PRINT.indd 79M3021 - SONG 978184844658 PRINT.indd 79 23/11/2012 14:5123/11/2012 14:51
80 The Chinese steel industry’s transformation
estimation). Thus, the application of the GMM estimation method is
appropriate in this context.
In all of the regressions, the estimated elasticity of intermediate inputs
ranges from 0.89 to 0.94 and is statistically significant at the 1 per cent
level. On average, they account for around 90 per cent of contributions
to the growth of total output. This finding shows that intermediate input
usage plays an important role in the value of production of China’s iron
and steel enterprises. This suggests that China’s iron and steel production
is focusing mainly on producing low- value- added products such as sec-
tions and wires, where output growth has been mainly driven by increasing
material inputs. As an example, long products accounted for 51.9 per cent

Total factor productivity and its determinants 81
of China’s steel product output in 2005 (CISA, 2008). This figure, though
declining over time, is still far greater than the corresponding share in
Germany (23.8 per cent), the United States (28.7 per cent), Japan (37.8 per
cent) and South Korea (43.3 per cent) more than a decade ago (Labson
et al., 1995). These countries are all important producers of flat products,
where value added in production is much higher. China’s relatively weak
penetration in flat products reflects that the fact that its industry is more
highly input- intensive relative to its relevant peers, especially in those
industrialized countries.
As a rough measure of returns to scale by adding up the elasticities
over all inputs, the GMM estimation shows that the production function
exhibits some characteristics of constant returns to scale or mildly increas-
ing returns to scale as shown by the bottom row in Table 4.2, which is
labelled ‘Wald test for IRTS’ (standing for ‘increasing return to scale’).
Although the hypothesis of constant returns to scale in the estimation with
the OLS, first- differencing and panel fixed- effects methods is significantly
rejected at the 1 per cent level, it is not rejected in the LP estimation (at the
1 per cent level). This suggests that even when SEs are taken into account
for estimating the production function, the industry still exhibits the sig-
nificant characteristic of constant returns to scale, or mildly increasing
returns to scale, when capital is correctly accounted for in the production
function by using the GMM estimation method. Thus, mergers and acqui-
sitions, especially those initiated by market impulses, should be further
encouraged to obtain the potential benefits from economies of scale in the
industry.
Based on the preceding analysis of the estimates under the GMM
method, we can use Equation (4.3) to extract an estimate of firm- level
TFP and examine the determinants. Figure 4.2 show the changes in the
mean and variance of China’s iron and steel firms’ TFP over time. Between
1998 and 2007, there was a significant increasing trend in average produc-
tivity at the firm level, with an annual growth rate of 2.1 per cent. This,
compared with the annual growth rate of firms’ average output of 7.8 per
cent, suggests that firm- level productivity growth accounted for 27 per cent
of output growth during that decade. A further analysis of the relationship
between the estimated TFP and some approximate determinants, such
as marketization reform, firms’ R&D investment, market structure and
firms’ export behaviour, shows that these factors play different roles in
affecting the productivity of China’s iron and steel enterprises, depending
among other things on different types (including firm size, R&D invest-
ment, ownership and exporting behaviour), as shown in Tables 4.4 and 4.5.
Based on the entire sample estimation, we can see that firms’ TFP is
generally positively related to R&D investment, firm size, market share

and marketization reform, while negatively related to market monopoly
power (measured by the Herfindahl index for the top eight firms), and firms’
capital/labour ratio. As is shown in columns (6) and (7) in Table 4.3, the esti-
mated elasticities for the firms’ R&D index, market share, the scale dummy
and the marketization index are all positive and statistically significant at the
1 per cent level, while the estimated elasticity of firms’ capital/labour ratio
and market monopoly level are negative and also significant at the 1 per cent
level (in both the random- effects and fixed- effects frameworks). The results
are robust to TFP estimations with the OP and LP methods. These results
imply that the operation of China’s iron and steel firms has been relatively
labour- intensive. This, together with firm size, a high proportion of private
ownership and strong market share positions, has contributed positively to
the improved level of productivity. However, exporting firms are less likely
to have relatively high productivity vis- à- vis non- exporting ones. Also, to
our surprise, the impact of R&D (the new products share index) on average
had no significant impact on TFP levels. This may be consistent with the
fact that a large number of iron and steel firms, especially non- state SEs,
were still using rather old and outdated technologies in their production,
and these firms had less spending on R&D.
When we split the whole sample into two categories characterized by
firm size – LMEs and SEs (as shown in Table 4.4) – we find that the
drivers for improving productivity differ substantially with firm size. For
the LMEs, different degrees of privatization generally have no significant

impact on their TFP performance (as shown in the fixed- effect model),
although new products do contribute to the improvement in productivity.
This result implies that the large state- owned steel enterprises have already
been competitive as compared with large private enterprises, because of
the reform measures implemented in the state sector (Ma et al., 2002).
However, for the SEs, those with high levels of privatization have signifi-
cant higher TFP than other types of SEs (in both the random- and fixed-
effect model), implying that the marketization reform was still important
for the large number of SEs in the industry.

84 The Chinese steel industry’s transformation
our estimation results show that SOEs are more likely to obtain productiv-
ity improvement through increasing R&D innovation and enlarged scale
of production from large capital investments; while the non- SOE LMEs
are more likely to obtain their productivity gains through exports. As
shown in Table 4.5, the estimated coefficient of exports for the non- SOEs
is positive and statistically significant at the 1 per cent level.
The next factor to consider is the industrial location. Iron and steel
firms have been physically distributed rather unevenly across different
regions. To examine different drivers of firms’ productivity related to loca-
tions, we have split the sample into three subgroups: the eastern, central
and western regions; the estimation results are reported in Table 4.6. We

highlight the following findings. Although the general impacts of the
firms’ capital/labour ratio and scale on their TFP are similar, the impact
of market share on productivity is much stronger in the eastern region
while the impact of marketization and market power is most evident in
the western region. This finding is consistent with the fact that market-
oriented reforms have been more thoroughly done in the eastern than both
the central and western regions as measured by the relatively low share of
SOEs in total industry in the eastern region. The increased competition
makes the changes in market share an important factor in influencing
firms’ productivity in the eastern region.
For the same reason, further reform in deepening the process of

marketization plays a more important role in those central and western
regions which have a less competitive environment owing to the relatively
slow progress in reform. Finally, although increasing firm size is positively
correlated to firm performance in TFP for all the three regions, it gener-
ates a much larger impact (as measured by the magnitude of the coefficient
estimates) in the western region than elsewhere.

This chapter has aimed to fill the gap left by previous studies in the
field that had not been able to reach a consensus on the level and pos-

sible drivers of TFP growth in the Chinese iron and steel industry. Our
approach was to correct some of the econometric problems that might
have constrained those previous studies by adopting the newly developed
econometric approaches. We then applied these approaches to a more up-
to- date sample covering the period 1998–2007.
The estimation results suggest that the previous studies have in all likeli-
hood underestimated the contribution of capital to industry output and
have correspondingly overestimated the contribution from intermediate
inputs resulting from the ‘endogenous input’ problem evident in previous
studies. Furthermore, our decomposition of derived TFP suggests that the
key drivers of productivity improvement differ substantially with respect
to differences in firm size, ownership type and geographical location.
Notably, the productivity of SEs is positively related to market share and
negatively related to R&D. For SOEs, firm- level productively is relatively
insensitive to market share and R&D, but more responsive to techno-
logical upgrading and marketization reform. The non- state large firms are
more likely to obtain their productivity gains through exporting. Finally,
increasing firms’ size is generally positively correlated to firms’ perform-
ance in TFP, and it is more so in the less- developed western than in the
eastern or central regions.
A policy implication from this study is that to further improve the pro-
ductivity and quality of Chinese iron and steel enterprises, different policy
instruments targeting firms with different characteristics in the process of
restructuring the industry may be desirable. For example, policy measures
aimed at market entry will work well for relatively small firms; further
progress on technological upgrading and marketization reform such as
development of shareholding will be more conductive to large SOEs; more
opportunities for trade will help improve productivity for non- state large
firms; and an increase in firms’ scale of production will be advantageous
for firms located in the western region.
NOTES
1. Ma et al. (2002) outline the increasing trend in the growing scale of existing firms.2. The estimation method can also be used for adopting other types of production func-
tions, provided some basic requirements are met (Ackerberg et al., 2005).3. This is not as straightforward a decision as it seems prima facie. As the marketiza-
tion reforms may have reduced the amount of bureaucracy employed in the industry without having a direct role in the production process, this may be an interesting effect to capture. However, we settled on this abstraction as we are most interested in proxying the ‘blue- collar’ workforce.

5. The technical efficiency of China’s large and medium iron and steel enterprises: a firm- level analysis
Yu Sheng and Ligang Song
INTRODUCTION
The expansion of China’s iron and steel industry since the 1990s has
been driven largely by the strong domestic demand resulting from the
accelerated pace of urbanization and industrialization. A key question is
whether the rapid expansion of the industry is also accompanied by any
significant gain in efficiency in the large and medium state- owned enter-
prises (SOEs) through institutional and ownership reform. The question is
significant in that the improvement of productivity in the industry could
be an indication that there has been some impact on those SOEs from the
series of marketization reforms in the industry including privatization and
corporate restructuring. To demonstrate that these reforms work in the
industry, it is important to connect the improvement in SOEs’ firm- level
productivity with the marketization reform from an empirical perspective.
This is the task of this chapter.
Historically, China’s iron and steel industry has been dominated by
the large and medium SOEs. In 1999, the industry consisted of 3042
enterprises, of which only 793 were state- owned or majority- state- owned
holding companies (accounting for 26 per cent of the total). However,
the total output value and total assets of these SOEs accounted for 74 per
cent and 89 per cent of the whole industry, respectively. The significant
advantages of SOEs in firms’ scale, market share and capital stocks over
their private counterparts in the industry were not accompanied by high
productivity and profitability. This is partly because the institutional
arrangement in those SOEs associated with their ownership led to inef-
ficiency in investment and management compared with the non- state-
owned enterprises.

90 The Chinese steel industry’s transformation
In order to solve the problem of inefficiency, the central government
has implemented a series of policies aiming to strengthen marketization
reforms of SOEs and encourage the entry of privatized enterprises to the
industry. As a consequence, more than one- third of SOEs were privatized
during the 1990s and into the new century, and the market share of non-
SOEs in the industry significantly increased. Between 1999 and 2005, the
total number of state- owned and state- holding enterprises reduced from
793 (accounting for 26 per cent) to 407 (accounting for 6.1 per cent). The
share of the output value of the state- owned and state- holding enterprises
over the industry total also reduced from 74 per cent to 47 per cent. In
particular, in the iron ore mining sector, the share of the total output value
of the state- owned and state- holding enterprises over the industry total fell
to 20 per cent in 2005.
Continuing marketization and privatization reform promoted market
competition in the industry and helped to improve SOEs’ production effi-
ciency and profitability, which in turn has further supported the expansion
of the top firms’ production levels. Between 1999 and 2007, the top 60 iron
and steel enterprises all expanded their production capacities, so that, by
2007, ten enterprises were each producing more than 10 million tonnes
of crude steel (after an annual growth rate of 22.9 per cent); 13 were pro-
ducing 5–10 million tonnes (after an annual growth rate of 9.3 per cent);
and 34 were producing 2–5 million tonnes (after an annual growth rate of
11.5 per cent). Reflected in the aggregate performance of the industry, the
total output of pig iron, crude steel and steel products in 2007 was 0.47
billion tonnes, 0.49 billion tonnes and 0.56 billion tonnes, respectively,
with annual growth rates of 20.3 per cent, 22.4 per cent and 24.7 per cent,
respectively.
This chapter examines the impact of marketization reforms on firm-
level productivity for large and medium enterprises during the period
1999–2005. Rather than using the data for the whole industry, this study
focuses on the data from 60 major SOEs in China’s iron and steel industry
to test the hypothesis that these reform measures affect firms’ performance
by changing the institutional arrangements which tend to improve the
technical efficiency of these firms. In particular, we distinguish between
the impacts of different ownership arrangements on enterprises’ techni-
cal efficiency and highlight the important role that iron ore has played in
affecting the technical efficiency in SOEs’ production. The latter point has
some important policy implications for securing the long- term supply of

MARKETIZATION REFORM AND LARGE STATE- OWNED ENTERPRISE: LITERATURE REVIEW
The marketization reform in China’s iron and steel industry started in
the late 1970s, but the main changes in ownership at the enterprise level
did not take place until the early 1990s. The initial purpose of the reform
was to establish a modern management system within the large iron and
steel enterprises so as to improve firm- level productivity and profitability.
Between 1994 and 1998, there had been 12 SOEs (including Wu Gang,
Ben Gang, Tai Gang, Cong Gang, Ba Yi, Tianji Steel Tube and Da Zhi)
involved in the national pilot reform programme and 57 SOEs (including
Han Gang, Fushun Gang, Tianjin Gang and Jiuquan Gang) in the local
pilot reform programme.
Since 1998, further marketization reforms have been extended to
restructure all SOEs in the industry. A series of reform measures have been
carried out (following the new Cooperation Law), including attempts to
clarify the property rights, strengthen the principal–agent relationship (or
ownership) and set up the modern management and corporate finance
systems. This helped to eliminate institutional barriers for SOEs in the
industry which were associated with the legacies of central planning under
which there was very little autonomy at the firm level with respect to
decision- making.
In 2003, the National Development and Reform Commission (NDRC)
implemented the ‘About Restricting Iron and Steel Firms’ Rush
Investment’ and ‘Iron and Steel Industry Development Strategy’ (NDRC,
2003) to regulate firms’ production and market competition. Through
strengthening government policy direction, raising the threshold for
market entry, and tightening the arrangements around bank loans, the
new policy succeeded in preventing 345 projects – recognized as duplicate
or redundant construction by NDRC – from entering the industry. The
government also managed to close down 12.9 million tonnes and 13.1
million tonnes of outdated production capacity for iron and steel in that
year. These policies, followed by ‘Accelerating Structural Change in the
Iron and Steel Industry’ implemented by the NDRC in 2006 (NDRC,
2006), helped to restrict the duplication of investment in the industry and
provide an improved market environment for large and medium iron and
steel enterprises.
In recent years, some domestic SOEs in the industry have started to
enter the international market through public listing (for fund- raising) and
investment in overseas iron ore operations. Through mergers and associa-
tions with some upstream and downstream enterprises, some SOEs in the
industry have succeeded in building up their competitive advantages. As a
M3021 - SONG 978184844658 PRINT.indd 91M3021 - SONG 978184844658 PRINT.indd 91 23/11/2012 14:5123/11/2012 14:51
92 The Chinese steel industry’s transformation
consequence, importing iron ore from, and exporting iron and steel prod-
ucts to, the international market have become significant characteristics
of these enterprises. These characteristics reflect the fact that the iron and
steel industry in China has become more deeply integrated with the world
market, providing some evidence that the predominant character of the
production upon which China’s comparative advantage lies has begun to
shift from labour- intensive to capital- intensive. Much as in other sectors,
the market integration process helps to improve the productivity at firm
level.
Marketization reform in China’s iron and steel industry has been suc-
cessful and helped to improve enterprises’ productivity, particularly for
those SOEs during the period under study. There are two main channels
through which the positive impacts of marketization reforms impact on
firms’ performance. First, marketization reform can improve SOEs’ tech-
nical efficiency through strengthening the within- firm incentive mecha-
nism. Second, marketization reform can regulate the market environment
and intensify market competition, leading to the reallocation of market
share to more efficient enterprises. This will help to nurture within- firm
innovation and maintain the long- term productivity growth of SOEs.
These two impacts of marketization reform are frequently referenced in
the literature on privatization. In this chapter we provide the empirical evi-
dence as to whether these positive impacts of marketization are working
for the large and medium SOEs in the steel industry in China.
There have been a large number of studies on China’s iron and steel
industry, including, among others, Jefferson (1990); Kalirajan and Cao
(1993); Wu (1996, 2000); Zhang and Zhang (2001); Nolan and Yeung
(2001); Ma et al. (2002); Movshuk (2004); and Sun (2005). These studies
focus mainly on the firm- level analysis from three aspects. Jefferson (1990)
was the first to use both the Cobb–Douglas and the log–linear production
functions to estimate the multifactor productivity for China’s iron and
steel industry with 120 large and medium enterprises in 1986. Thereafter,
Kalirajian and Cao (1993) and Wu (1996) adopted a stochastic frontier
production function to estimate technical efficiency with 1988 data for 97
and 87 enterprises; and Zhang and Zhang (1999) used the 1995 national
industrial census data to examine the production frontier of iron and steel
firms.
As more time- series data were released in China’s Iron and Steel
Industrial Yearbook, Ma et al. (2000) used data envelope analysis with
panel data for 88 enterprises during the period 1989–1997, and Movshuk
(2004) used the stochastic frontier analysis with 82 enterprises for the
period 1988–2000 to examine firms’ productivity and technical efficiency
and discuss the impact of economic reform on China’s iron and steel
M3021 - SONG 978184844658 PRINT.indd 92M3021 - SONG 978184844658 PRINT.indd 92 23/11/2012 14:5123/11/2012 14:51

industry. Nolan and Yeung (2001) and Sun (2005) did their case studies on
Shou Gang Group in Beijing and Bao Shan Group in Shanghai, respec-
tively, these companies being the two largest iron and steel enterprises in
China respectively. The authors analysed changes in the productivity and
competitiveness of China’s iron and steel industry and its catch- up with
the advanced level of world production.
However, these reviewed studies did not provide consistent findings
with respect to the impact of marketization on SOE firms’ performance,
and in some cases contrary results emerged. For example, Movshuk (2004)
found that there had been no significant increase in the technical efficiency
of China’s iron and steel industry, particularly in the four largest enter-
prises, and argued that the impacts of major reform measures on enter-
prises’ technical efficiency were weak during the 1990s. Ma et al. (2000)
found however that the estimated technical efficiency of China’s iron and
steel firms increased from 58 per cent in 1989 to 66 per cent in 1997. There
have also been some differences with respect to the performance of the
four largest enterprises according to Ma et al. (2000) and other studies
such as Nolan and Yeung (2001) and Sun (2005).
Further studies are therefore needed to re- examine the relationship
between marketization reform and the productivity and technical effi-
ciency of SOEs in China’s iron and steel industry, especially after 2000. In
this chapter, we apply the stochastic frontier model with the unbalanced
panel data of 68 large and medium- sized SOEs. Contributing to the lit-
erature in the field, we incorporate intermediate goods into the log–linear
production function so as to improve the accuracy of the productivity esti-
mation with a better control of the returns- to- scale effect in production.
The results show that marketization reform has significantly promoted
SOEs’ productivity and technical efficiency during the decade to 2005,
although such an impact varies across different types of reform.
STOCHASTIC FRONTIER METHOD AND EMPIRICAL MODEL SPECIFICATION
Traditional production theory is based on the assumption that the behav-
iour of production units is optimal. Under the conditions of perfect
competition, a production unit will produce at the most efficient point
that satisfies the objective of profit maximization. It is assumed that pro-
duction units optimize from a technical or engineering perspective by not
wasting resources, and that they operate up to their maximum potential
output with available input resources. Production units are also assumed
to optimize from an economic perspective by solving allocation problems
M3021 - SONG 978184844658 PRINT.indd 93M3021 - SONG 978184844658 PRINT.indd 93 23/11/2012 14:5123/11/2012 14:51
94 The Chinese steel industry’s transformation
that involve prices, – that is, they locate the input resource effectively so as
to operate on, rather than above, their minimum cost boundary.
However, in practice, for various reasons, not all production units
succeed in working at optimal levels, since firms may have the incomplete
nature of knowledge of best practice and other organizational factors.
Therefore, it is important to have a way of analysing the degree to which
production units fail to optimize, and the extent of the departure from the
most efficient level. In response to these needs, advanced econometric and
mathematical methods have been developed, among which the stochastic
frontier method has emerged and attracted much attention in the applied
analyses.
In order to examine the production efficiency of the Chinese iron and
steel industry, we estimated a stochastic frontier model as described
by Battese and Coelli (1995), or the BC model for short. While early
stochastic frontier models were devised for cross- sectional data, the BC
model is formulated for panel datasets that may be unbalanced. The
model not only estimates inefficiency levels of particular enterprises,
but also explains their inefficiency in terms of potentially important
explanatory variables. The model decomposes TFP growth into three
components: technological growth (essentially, a shift of the production
possibility frontier, set by best- practice enterprises); inefficiency changes
(that is, deviations of actual output level from the production possibility
frontier); and scale- mix effects (output change due to increasing returns
to scale).
Conventionally, stochastic frontier models contain a production func-
tion f ( . ) and the disturbance term ei,t:
ln (Yit) 5 ln [f (Xit; b)] 1 eit, (5.1)
where Yit is the production for the ith company in year t, Xit is the vector
of independent variables (inputs, etc.), b is the corresponding vector of
unknown parameters to be estimated, and f ( . ) denotes a production
function (in the form of a translog, or Cobb–Douglas, production func-
tion, or similar).
The disturbance term is defined by eit 5 vit 2 uit, where vit is a conven-
tional systematic random disturbance term, associated with the impact of
omitted variables on the output variable, and uit is a non- negative random
term, representing various inefficiencies in production. The random dis-
turbance term vit is assumed to be following an independent and identical
normal distribution (i.i.d.) with mean zero and variance s2v, while uit is
obtained by non- negative truncation of the normal distribution with mean
mit and variance s2u.

Technical efficiency of large and medium enterprises 95
In the BC model, the mean of the inefficiency term uit is defined by:
mit 5 zitd, (5.2)
where zit is the vector of variables that explain technical inefficiency and d
is the corresponding vector of unknown parameters to be estimated.
The model was estimated by applying the method of maximum
likelihood, using the computer programme frontier (version 4.1) of
Coelli (1996), with variance parameters expressed by s2 5 s2v 1 s2
u and
g 5 s2u/s
2. Technical efficiency TEit of the ith enterprise in year t equals
the ratio of observed output level to the estimated frontier output level:
TEit 5Yit
exp [ f (Xit; b) ]5 exp (2uit
) . (5.3)
The inefficiency component uit in Equation (5.3) is not observable, but can
be estimated by using the minimum squared error predictor of uit:
E [exp (2uit0eit
) ] 5 [exp (2m*it 1 12s
2*) ]
[�(m*it/s*) 2 s* ]
�(m*it/s*), (5.4)
where m*it 5 [s2v(d rzit
) 2 s2u(eit
) ] /s2,s2* 5 s2
vg, and �( . ) is the cumulative
distribution function of a standard normal variable.
Using the estimates of TEit from Equation (5.4), the index of technical
efficiency change DTE for the ith enterprise between time periods t and s
was calculated by:
DTE 5TEit
TEis
. (5.5)
Following Coelli et al. (1998), the index of technical change DTCh
between periods t and s was obtained from
DTCh 5 e c1 10f (Xis, s, b)
0sd 3 c1 1
0f (Xit, t, b)
0td f 1/2
, (5.6)
where the index of TFP growth DTFP will be calculated.
In production function f(.), production Yit was dependent on two
inputs, capital Kit and labour Lit, as well as time t. We estimated two con-
ventional production functions – a quadratic form in Equation (5.7) and a
more restricted Cobb–Douglas form in (5.8):

The hypothesis testing was performed by the generalized likelihood
ratio (LR) statistic:
l 5 22 ln cL(H0)
L(H1)d , (5.9)
where L(H0) and L(H1
) are the values of likelihood function under the
null and alternative specifications. The l statistic is non- negative, and
follows c2r distribution under the null hypothesis, where r denotes the
number of restrictions.
To examine various potential determinants of inefficiency in the specifi-
cation (5.2), we considered several sets of zi. They are (1) capital intensity
to account for firms’ specific characteristics; (2) scale to capture the rela-
tive size of the firms; (3) the marketization index; and (4) firms’ long- term
investment.
Overall, the inefficiency model (5.2) was specified as follows:
mit 5 d0 1 d1Ageit 1 d2 ln kit 1 d3Scaleit 1 d4Mktit
1 d5Linvit 1 d6Dexpit 1 d7Drestaxit 1 d8R4 1 .it, (5.10)
where Ageit denotes the enterprise’s age; kit denotes the capital labour
ratio; Scaleit denotes the relative scale of enterprises; Mktit the marketiza-
tion index; and Linvit the ratio of the long- term investment over total fixed
assets. Dexpit, Drestaxit and R4 are three dummy variables, representing
the enterprise’s exports, resource tax and whether they are the four largest
iron and steel enterprises. A particular feature of the specification (5.10) is
that its parameters dj (j 5 1, 2, 3, 4, 5, 6, 7, 8) measure the impact of those
listed variables on firms’ technical inefficiency.
DATA AND ESTIMATION RESULTS
The primary source of firm- level data used for this study was the Annual
Financial Report of Large and Medium Iron and Steel Firms (CISA, various
M3021 - SONG 978184844658 PRINT.indd 96M3021 - SONG 978184844658 PRINT.indd 96 23/11/2012 14:5123/11/2012 14:51

years). The annual reports provide data on output with both current
and constant prices; the total and net fixed assets; total and working (or
‘congye’) labour at the end of year; and various financial and other indi-
cators for about 130 large enterprises. We compiled an unbalanced panel
dataset, with data reported for most variables covering the seven- year
period 1999–2005. Table 5.1 reports the basic statistics relating to the
dataset. Overall, these enterprises accounted for about half of gross output
and valued added in China’s iron and steel industry, and 53 per cent of
total employment and 48 per cent of total fixed assets.
The annual report contains different measurements for gross output
value over time: gross industrial output value (both in real terms with 1990
constant prices and in nominal terms) for the period 1999–2003, and gross
industrial output value (only in nominal terms) for the period 2004–2005.
In order to make these data consistent over time, we use the ex- factory
price index to adjust the gross output value for both 2004 and 2005.
We use the method provided by the Chinese National Bureau of
Statistics (CNBS) to estimate the value of the intermediate inputs, which
is equal to the gross output value minus value added and then plus value-
added tax. Since major intermediate inputs in the iron and steel industry
are coal (or electricity) and iron ore, the price index of energy and mate-
rials is used to make the adjustment for inflation. For capital input, we
used the net value of fixed assets (in nominal terms) as the initial value.

98 The Chinese steel industry’s transformation
The accumulated price index of investment in fixed assets was calculated
for 2000 with the data from the China Statistical Yearbook (CNBS, 2006),
and used for discounting the net fixed assets in 2000. For latter years, we
used the net fixed assets in 2000 with constant prices plus the increased
part of the changes in the net fixed assets adjusted with the current- year
price index of investment of fixed assets. Finally, all of the capital is mul-
tiplied by 0.817 to generate the capital used for direct production, since
iron and steel enterprises in China usually have some proportion of assets
which are not productive (Jefferson, 1990).
For labour input, we use the total congye (on- job) labour at the end
of year for the period 2002–2005. For the years before 2002, we use the
average ratio between working labour and total labour for the period
2002–05 as an index to discount the total labour at the end of the year
for the period 1999–2001. The reason we made this approximation was
to make sure that the ratio between working labour and total labour was
consistent over time.
To capture the impact of marketization reform on SOEs’ technical effi-
ciency, we further define two groups of indices (for marketization reform)
based on firms’ registered capital: one group is the share of non- state-
owned capital in the total registered capital and the other group is the
shares of each type of non- state capital in the total registered capital. The
former index is used to examine the average impact while the latter is used
to explore the relative impact of different types of marketization reforms.
We use three shares to roughly capture the three types of marketization
reforms: legal person share for mutual purchase or firms’ restructuring
reform; individual share for shareholding reform; and FDI share for the
openness reform. Finally, we also distinguish SOEs with different export-
ing and importing behaviours by using the dummy variables.
MARKETIZATION REFORM, INTERNATIONAL TRADE AND SOES’ TECHNICAL EFFICIENCY
Technological Progress vs. Technical Efficiency
Based on Equations (5.7) and (5.8), we estimate the technical efficiency of
the large and medium- sized SOEs in China between 1999 and 2005. Table
5.2 shows the estimation results based on the Cobb–Douglas and quad-
ratic production function.
An important finding from the estimation is that the values of g
(defined as sigma- v/sigma- u) in the two sets of models range from 0.92 to
0.96, which is close to unity. This suggests that technical inefficiencies are
M3021 - SONG 978184844658 PRINT.indd 98M3021 - SONG 978184844658 PRINT.indd 98 23/11/2012 14:5123/11/2012 14:51
Technical efficiency of large and medium enterprises 99
significant in the sample firms and the application of the technical inef-
ficiency model would be appropriate. Moreover, the log- likelihood test
(LR) for the null hypothesis that the interaction terms in the quadratic
specification are jointly insignificant is 27.36, which is larger than the
critical value of 17.75 at the 1 per cent level (Kodde and Palm, 1986). This
implies that the quadratic function form is more suitable than the Cobb–
Douglas form.

100 The Chinese steel industry’s transformation
Based on the quadratic production function, we introduce the time
trend variable into the production function model estimation to capture
changes in the technological progress of SOEs. Table 5.2 reports the esti-
mated coefficients of time trends in the production functions which are all
positive and statistically significant at the 1 per cent level, suggesting that
SOEs have made some positive technological progress over the period
under review. After controlling for the technological progress, a further
estimation shows that firms’ technical efficiency has also improved.
Between 1999 and 2005, the average technical efficiency of SOEs in our
sample was 80.9 per cent and the average coefficient of returns- to- scale for
the quadratic production function with intermediate inputs is 1.63. This
implies that our sample firms generally enjoy increasing returns to scale,
but there is still a large potential for them to increase their technical effi-
ciency. Two important implications of the changing technical efficiency of
SOEs can be made below.
First, although the average technical efficiency of enterprises was still
relatively low, it increased during the period 1999–2005 (Figure 5.1).
Second, the increase of enterprises’ technical efficiency came mainly
from the catch- up effect of the original low- efficiency enterprises. This
can be seen in the dramatic decrease in the number of low- efficiency
enterprises during the period 1999–2005. In terms of the determinants
of the technical efficiency of China’s iron and steel enterprises, different
factors have different effects and their various impacts can be summa-
rized below.

Marketization Reform and its Impacts on Technical Efficiency
In theory, the technological progress in large and medium SOEs can result
from continuous investment and R&D innovation, while technical effi-
ciency gain can be the result of marketization reform. Yet from the previ-
ous literature as reviewed earlier the empirical evidence on the positive
causal relationship between marketization reform and technical efficiency
is mixed. We intend to clarify this by estimating further the technical inef-
ficiency model (Table 5.3).
Two groups of marketization indices are incorporated into the second-
step technical inefficiency model following the production function esti-
mation. In Table 5.3, columns (2) and (4) report the results from the
regressions with the total non- state- owned share of capital, and columns
(3) and (5) report the results from the regressions with each individual
non- state- owned share of capital. The share of aggregated non- state-
owned capital in the total registered capital stock is used as an approxima-
tion of the overall marketization reform, and the estimated elasticity of the
variable is positive, but statistically insignificant at the 10 per cent level.
This result seems to suggest that marketization reforms have made no
significant contribution to the improvement of SOEs’ technical efficiency
(the finding is consistent with those reported in the existing literature).
However, when the non- state- owned capital share is split according to
ownership type, to capture the relative impact of different marketiza-
tion reforms, the estimated results show that the elasticity of legal person
share is positive and statistically significant at the 1–5 per cent level while
those of individual share and FDI share are negative and significant at the
1–5 per cent level. This implies that different marketization reforms may
produce some differing impacts on the large and medium SOEs’ technical
efficiency in the industry. In particular, the shareholding reform (repre-
sented by the individual share) and the openness reform (represented by
the FDI share) have helped to reduce the production inefficiency of SOEs,
while the mutual purchase or firms’ internal restructuring (represented by
the legal person share) does not. This mixed result is probably the main
reason why the impact of marketization reform at the aggregate level on
firms’ technical efficiency is not significant.
As for the impact of other factors on firms’ technical efficiency, the
elasticity of firms’ capital/labour ratio ranges from 0.77 to 1.08 and is
statistically significant at the 1 per cent level. This implies that a 1 per
cent increase in firms’ capital/labour ratio may lead to a 0.77–1.08 per
cent decline in technical efficiency, even though an increase in the capital/
labour ratio may enhance technological efficiency. This finding implies
that making use of the comparative advantage with respect to labour is

102 The Chinese steel industry’s transformation
still an important factor for improving SOEs’ technical efficiency. The
result is consistent with the insignificant estimates of labour elasticity in
the production function. Finally, the coefficients of exports and resource
tax are negative and statistically significant at the 1 per cent level. This
suggests that openness to trade and market- oriented administration (for
example, the imposition of the resource tax) may nurture entrepreneurship
and tend to reduce the inefficiency of SOEs.

Technical efficiency of large and medium enterprises 103
IMPORT OF IRON ORE AND SOES’ PRODUCTION EFFICIENCY
How will imports of iron ore from the world market affect China’s iron
and steel industry’s production efficiency? Owing to the endogeneity and
the reverse causality problem, we cannot simply run a regression to find
the causal relationship between imports of iron ore and firms’ efficiency.
An alternative way of dealing with this issue was to split the sample enter-
prises into three groups: those which used only domestically supplied iron
ore, those which relied on imports of iron ore for less than 50 per cent of
total demand, and those which depended on imports of iron ore for 50 per
cent or more of total demand. The estimated technical efficiencies in all
these three types of enterprises were then compared.
We found that the SOEs with imports of iron ore of 50 per cent or
more of their total demand were more technically efficient than those with
imports of iron ore less than 50 per cent of demand and those with no
imports of iron ore at all. Figure 5.2 shows the comparison of technical
efficiency among the three groups of enterprises from both a comparative
static perspective and a dynamic one. Figure 5.2(a) shows that the average
technical efficiency of enterprises with imports of iron ore of 50 per cent or
more was 82.1 per cent, which was higher than those with imports of less
than 50 per cent and those with no imports (80.9 per cent and 80.1 per cent,
respectively). In particular, from a dynamic perspective, the enterprises
with positive imports of iron ore were significantly more efficient than
those with no imports of iron ore (Figure 5.2(b)). This implies that imports
of iron ore from the international market tended to improve technical effi-
ciency of enterprises in China’s iron and steel industry. A possible expla-
nation is that intermediate inputs played an important role in increasing
the total output, and the imports of iron ore from the international market
were usually of better quality than the domestic supplies in terms of iron
content. Those enterprises which exclusively used domestically supplied
iron ore might incur much higher costs of sifting iron ore and producing
iron and steel products that would affect their level of efficiency.

104 The Chinese steel industry’s transformation
CONCLUSIONS
This chapter has examined the technical efficiency of large and medium
SOEs in China’s iron and steel industry between 1999 and 2005, apply-
ing a stochastic frontier model with the unbalanced panel data. We
found that SOEs in the iron and steel industry have generally experienced
rapid improvement in production (technical) efficiency resulting from the
marketization reform which has been implemented over the same period
as part of China’s overall economic transformation towards a market
economy. Although different types of reforms may bring about different
impacts on enterprises’ performance, those marketization reform meas-
ures such as shareholding reform and openness to trade and investment

have helped to promote the improvement of SOEs’ technical efficiency
more than other measures. Finally, firms’ trade orientations such as
exports of iron and steel products and imports of iron ore have also played
an important role in affecting enterprises’ technical efficiency, which
deserves some further exploration in future.

6. The backward and forward linkages of the iron and steel industry in China and their implications
Yu Sheng and Ligang Song
INTRODUCTION
A unique feature of the iron and steel industry is that it has some close
relationships both upstream and downstream, in that the rapid expan-
sion of the industry may influence the performance of both the upstream
and downstream industries, possibly through cross- industry productiv-
ity spillover. Capturing this spillover effect is the subject of this chapter.
Following the recent literature analysing firm- level productivity (Javorcik,
2004), the chapter examines the cross- industry productivity spillover of
the iron and steel industry using firm- level data in the Chinese manufac-
turing sector over the period 2000–03. After controlling for the potential
endogeneity problem, we find that increases in the average productivity
of firms in the iron and steel industry may promote firms’ productivity
downstream but might not be conducive to firms’ productivity upstream.
When firms’ heterogeneity in operation size and productivity are consid-
ered, the results show that medium and small firms with low productivity
downstream are likely to benefit more from the productivity growth of the
Chinese iron and steel industry.
This chapter makes the following contributions. To begin with, the
study is the first to use firm- level data to explore the cross- industry link-
ages in China’s iron and steel industry. This allows us to examine more
closely the impact of China’s iron and steel industry on other related man-
ufacturing industries, with some useful policy implications being drawn.
Second, the data used in this chapter are unbalanced panel data, coming
from the Annual Manufacturing Enterprise Census. This data set covers
all firms (including entering and exiting firms) for each industry and each
year, enabling us to avoid the selection bias problem (usually suffered by
a number of studies in the literature which relied primarily on the survey
data). Third, we introduce firms’ heterogeneity in exploring the cross-
M3021 - SONG 978184844658 PRINT.indd 106M3021 - SONG 978184844658 PRINT.indd 106 23/11/2012 14:5123/11/2012 14:51

industry spillovers in the iron and steel industry. Adopting this approach
assists an understanding of the channels through which the backward and
forward linkages of the iron and steel industry are transmitted.
CROSS- INDUSTRY LINKAGE OF THE IRON AND STEEL INDUSTRY IN CHINA
It is found in the literature that the rapid development of a firm or an
industry may not only generate positive spillovers to firms and industries
in its neighbourhood, but also affect firms and industries operating in
the upstream and downstream sectors through the cross- industry linkage
(Krugman, 1991, 1998; Venables, 1996). To see how such a cross- industry
linkage works, we assume that a firm or industry has a strong input–output
linkage with other firms and industries through purchasing the interme-
diate inputs from the upstream industries and selling the outputs to the
downstream ones. On one hand, as the productivity of the firm or industry
increases, it may generate additional demand for inputs from the upstream
firms and industries. The improved demand may intensify market compe-
tition of the upstream firms and thus increase their productivity. On the
other hand, the improved productivity of the firm and the industry may
also raise the quality of outputs for the downstream firms and industries
so as to promote their productivity through decreasing production costs
and nurturing new products. Furthermore, an increase in productivity of
the firm or industry is likely to encourage larger- scale operations which
strengthen the standardization in the manufacturing process of indus-
trial goods, promoting the productivity of all industries. These effects
are usually defined as the backward and forward linkages of a firm or an
industry in relation to its upstream and downstream firms or industries.
As one of the most important pillar industries, the iron and steel
industry in China has a strong linkage with other industries throughout
the manufacturing sector and beyond. It provides the basic materials for
most manufacturing sectors producing goods sold in both the domestic
and international markets. According to the China National Bureau of
Statistics (2008), in 2007 around 423 million tonnes of crude steel were
produced and consumed by the manufacturing industries such as metal
producers, machinery manufacturers, construction and so on which
account for 30 per cent of the total outputs of these industrial sectors.
In addition, with China’s underlying comparative advantage shifting
towards more capital- intensive products, the steel industry plays an
important role in supporting China to become a ‘manufacturing factory
of the world’ (UNSD, 2011).1 The industry also supports the primary
M3021 - SONG 978184844658 PRINT.indd 107M3021 - SONG 978184844658 PRINT.indd 107 23/11/2012 14:5123/11/2012 14:51
108 The Chinese steel industry’s transformation
industries upstream such as coal- mining, iron ore mining, electricity gen-
eration, and so on. In terms of the backward linkage, the iron and steel
industry in China consumes 85 per cent of coking coal, 20 per cent of
electricity and almost all of the iron ore supplied from both domestic and
overseas sources. The strong cross- industry linkage between the Chinese
iron and steel industry and other manufacturing industries suggests that
any increase in productivity of the steel industry may spill over to those
upstream and downstream industries.
However, it remains to be tested empirically to what extent such cross-
industry linkage effects would exist between the Chinese steel industry and
other industries. Some previous studies have explored the backward and
forward linkage of foreign direct investment (FDI) in China’s manufac-
turing sector from an empirical perspective. For example, Lin and Saggi
(2004) used firm- level data to examine the backward and forward link-
ages of FDI inflow at the two- digit China Industry Classification Code
(CICC) level in the Chinese manufacturing sector and found that there
have been significant positive backward and forward linkages between
both FDI and domestic firms in terms of technological spillovers. Hu
and Jefferson (2002), Hu et al. (2008) and Harrison et al. (2008) use the
2002 input–output table and firm- level data to re- examine the backward
and forward linkages of FDI in China at the three- digit International
Standard Industry Code (ISIC) level. They found that the backward and
forward linkages of FDI in China’s manufacturing sector are weak and
part of the reason is due to the large proportion of the processing indus-
tries which trade on international markets. However, there have been no
studies examining the cross- industry linkages of the Chinese iron and steel
industry with other industries. To fill the gap, this chapter aims to examine
systematically such linkages by using firm- level data and the recent input–
output table.
DATA COLLECTION, VARIABLE DEFINITION AND DESCRIPTIVE STATISTICS
The data used in this study are the firm- level data constructed by using
the Annual Manufacturing Enterprise Census, conducted by the China
National Bureau of Statistics (CNBS), for the period 2000–03. The
Annual Enterprise Census covers all state- owned firms and non- state-
owned enterprises with annual sales above 5 million yuan in Chinese
manufacturing sectors across all 32 provinces and metropolitan cities.
These enterprises accounted for more than 95 per cent of the total value
of Chinese industrial output during this time. The sample used is an

unbalanced dataset at the firm level, including those firms which enter
and exit each year. The total number of observations in the sample varies
from 134 130 in 2000 to 169 810 in 2003. At the two- digit (CICC) level,
the sample covers 26 different industries (with the CICC ranging from 13
to 42), which is split into two groups. The first group is the iron and steel
industry, including three manufacturing sectors: smelting and pressing of
ferrous metals (33), smelting and pressing of non- ferrous metals (34), and
manufacture of metal products (35); the second is its upstream and down-
stream industries including the 23 other manufacturing industries.
Table 6.1 provides some descriptive statistics of the sample: the number
of firms, the average value of output, and firm inputs such as labour,
capital and the intermediate inputs for both the iron and steel industry
and its upstream and downstream industries. The real output of firms, Y,
is defined as the total value of the sample firms’ output, deflated by the
producer price index at the firm level. Labour input, L, is defined as total
employment. As employment data are not available for 2003, we use regis-
tered labour (‘zaigang’) as a substitute. Although there are a large number
of non- productive workers in Chinese firms, there was a strong correlation
(about 95 per cent) between total employment and zaigang labour at the
firm level in 2000. Therefore, using zaigang workers as a proxy for total
employment in 2003 is appropriate. Capital, K, is defined as the value of
fixed assets at the end of the year, deflated by using the price index for
investment at the industry level. Intermediate inputs, M, is the value of
total output less value added, plus the net value- added tax, deflated by the
intermediate input deflator at the industry level. All value variables are
deflated, with 1990 the base year.
The key variable of interest in this study is the measure of firm’s pro-
ductivity, i.e. total factor productivity (TFP). Following the standard
literature in the field of growth accounting, we assume that the TFP
of representative firm i in industry j and region r at time t takes the para-
metric form of
ln TFPijrt 5 ln Yijrt 2 b̂jl ln Lijrt 2 b̂jK ln Kijrt 2 b̂jM ln Mijrt, (6.1)
where Yijrt is firm i’s output, and Lijrt, Kijrt and Mijrt are labour, capital and
intermediate inputs used in production. bjl, bjk and bjm are the estimated
elasticities of labour, capital and intermediate inputs to output by indus-
try. Although the simple ordinary least squares (OLS) regression technique
with the adjustment of heteroscedasticity can be used to provide estimates
of various input elasticities, its results are criticized for the potential over-
estimation due to the positive correlation between firms’ choice of capital
and their unobserved productivity level. As Olley and Pakes (1996) and

Backward and forward linkages of the Chinese steel industry 111
Levinsohn and Petrin (2003) point out, firms’ inputs like capital should
be considered as endogenous since managers choose their usage rates of
machinery based on production cost and productivity considerations that
are observed only by producers and not by econometricians. Without
properly accounting for firms’ endogenous input, choices may lead to
biased estimates of inputs elasticities and thus firms’ TFP. To deal with
this problem, we adopt the Levinsohn and Petrin semi- parametric method
to estimate the elasticity of labour, capital and intermediate inputs in each
two- digit (CICC) level industry and use Equation (6.1) to calculate the
firm- level TFP (see the appendix for more details).
To examine the cross- industry productivity spillovers of the iron and
steel industry in China, we defined two variables called the forward and
backward productivity linkage, respectively, following Javorcik (2004).
The forward productivity linkage of the iron and steel industry is
defined as the aggregated firms’ average productivity in the three com-
ponent manufacturing sectors defined above, weighted by the propor-
tion of each if these three sectors’ output supplied to the specific sector
Up_Steeljt 5 Sk,k2 jajkTFPkt, where ajk is the proportion of sector j’s output
supplied to sector k. The backward productivity linkages of the iron and
steel industry are defined as the aggregated firms’ average productivity
in the three sectors weighted by the proportion of the specific sector’s
domestic output (total output minus exports) supplied to each of the three
Down_Steeljt 5 Sk,k 2 jsjk[Si,i[kTFPikt*(Yikt2Xikt
)/(Si,i[kYikt 2 Xikt) ], where
sjk is the share of inputs purchased by sector j from sector k in total
intermediate inputs sourced by sector j. Both ajk and sjk are taken from
the 2002 input–output matrix at the two- digit industry level. The two vari-
ables of forward and backward productivity linkage capture the possible
linkage between the industry and its upstream and downstream sectors.
Tables 6.2 and 6.3 present the backward and forward linkages between
the three component sectors in the iron and steel industry in China and
other manufacturing industries, in terms of firms’ productivity and its
change over time reflected in the input–output table. There are three key
features that can be observed: (1) the forward linkage is more significant
than the backward linkage, though both of them are increasing over time.
The average forward linkage across the 26 manufacturing industries is
around 2.2 per cent, which is more than twice the forward linkage, at 1.0
per cent. (2) In terms of the cross- industry distribution of their impacts,
the forward linkage focuses on some high value- added industries, while
the backward linkage focuses on the low- value- added industries. The top
four industries being affected by the forward linkages include: metal prod-
ucts, general and special purpose machinery, communication equipment,
and computers and other electronic equipment. Those affected by the

114 The Chinese steel industry’s transformation
backward linkages were processing of petroleum, coking, processing of
nuclear fuel, other manufacturing industries, non- metallic mineral prod-
ucts, and general- purpose machinery. (3) The cross- industry input–output
linkages among the manufacturing sector have been weakening over time
(Table 6.3). Out of 26 industries, 20 decreased the relative share of pur-
chased intermediate inputs from domestic firms in their total inputs, and
21 decreased the share for outputs.
Finally, we define some firm- specific and industry- specific variables,
which are used to deal with the omitted variable problems due to the
potential correlation between these variables and firms’ productivity in
different regression models. More specifically, we define the Herfindahl
index of the industry as the output share of the top eight largest firms in
the industry to control for the negative relationship between the monopoly
power in market and firms’ productivity estimates. Also, we define the
number of products as a proxy for the firms’ production strategy relating
to output choice, so as to control the positive correlation between firms’
portfolio strategy in output and their productivity.
MODEL SPECIFICATION AND ESTIMATION STRATEGY
It is argued that an increase in firm productivity of the three component
sectors in the iron and steel industry helps improve firms’ productivity
in other industries outside the iron and steel industry through enforcing
market competition in the upstream industries and raising the quality
of the intermediate input supplied to the downstream firms. To measure
these backward and forward spillover effects of the iron and steel industry,
we start with applying two empirical specifications as below:

where TFPijrt denotes the TFP of firm i operating in sector j and region

116 The Chinese steel industry’s transformation
in firms’ total capital. Dt, Dr and Dj are time- specific, region- specific
and industry- specific dummies, used to control for time- specific, region-
specific and industry- specific effects.
Equation (6.2) is a basic empirical specification, which regresses firms’
TFP directly on the backward and forward linkages of the iron and
steel industry after controlling for the time- specific, region- specific and
industry- specific effects. Equation (6.3), as a robust check, controls for
four more variables, including the Herfindahl index for the top eight
largest firms in the industry, firms’ new product share, exporting dummy,
and foreign investment share. The reason for using Equation (6.3) is
that the estimation based on Equation (6.2) may suffer from the omitted
variable problem: the potential correlation between some factors in error
terms and the independent variables may lead to over- or underestimation
of their coefficients. For example, market competitiveness is argued to be
positively related to firms’ productivity and their cross- industry linkages.
Without considering the impact of such a factor, this may lead to overesti-
mation of the impact of the iron and steel industry through the backward
and forward linkages. Also, there are some firm- level factors, such as
firms’ new product share, export behaviour and foreign investment share,
which play an important role in affecting their productivity as well as their
linkage to the iron and steel industry.
Estimation of Equations (6.2) and (6.3) by using the OLS technique may
suffer from the endogeneity problem. When the backward and forward
linkages of the iron and steel industry are correlated with the unobserved
firm, region, sector, time- variant and - invariant factors in the error term,
the estimated coefficients on the backward and forward linkages would be
biased. Usually, if the correlation happens to be positive, the results would
be overestimated; if the correlation happens to be negative, the results
would be underestimated. For example, the rapid macroeconomic growth
and the continuous microeconomic reform might promote improvement
in firms’ productivity in both the iron and steel industry and its upstream
and downstream industries. Failing to consider this issue may lead to
the overestimation of the impact of the Chinese iron and steel industry’s
development on the whole manufacturing sector. Meanwhile, the open-
door policy tends to promote firms’ productivity but decreases the cross-
industry linkages between the domestic iron and steel industry and other
manufacturing industries. Failing to take this issue into account may lead
to the underestimation of the impact of the Chinese iron and steel indus-
try’s development on the whole manufacturing sector. To deal with this
problem, we first adopt the first- differencing (FD) regression technique
to eliminate the time- invariant firm- , region- and industry- specific factors
from our estimation and then include the dummy variables of Dr and Dj
M3021 - SONG 978184844658 PRINT.indd 116M3021 - SONG 978184844658 PRINT.indd 116 23/11/2012 14:5123/11/2012 14:51
Backward and forward linkages of the Chinese steel industry 117
so as to control for those time- varying factors. Thus, Equations (6.2) and
(6.3) can be re- arranged as follows:
d ln TFPijrt 5 b0 1 b1d ln Up_Steeljt 1 b2d ln Down_Steeljt
1altDt 1agrDr 1acjDj 1 uijrt; (6.4)

1altDt 1agrDr 1acjDj 1 uijrt, (6.5)
where d( . ) denotes changes in related variables over time.
To examine how firms’ characteristics, such as their scale of opera-
tion and productivity level, may affect their linkage to the iron and steel
industry, we further split our sample into subgroups: larger versus medium
and small firms, and the most productive versus the least and medium
productive firms. Regressions, based on Equations (6.2) to (6.5), are thus
reapplied to those subgroups:
ln TFPkijrt 5 b0 1 b1 ln Up_Steel

where k represents the subgroup of firms according to their operational
size and productivity levels.
However, the OLS and FD estimates may still overestimate the cross-
industry linkages of the iron and steel industry without making the correc-
tion for clustering effects. As Moulton (1990, p. 334) argued,
when one tended to use the aggregate market or public policy variables to explain the economic behaviour of micro units, it is possible that the standard
M3021 - SONG 978184844658 PRINT.indd 117M3021 - SONG 978184844658 PRINT.indd 117 23/11/2012 14:5123/11/2012 14:51
118 The Chinese steel industry’s transformation
errors of estimated coefficients of those aggregate variables from the OLS or FD might be underestimated (or inefficient), which would lead to the over-stated significance of coefficients.
The presence of group- level variables in such a ‘structural’ model can
be viewed as putting additional restrictions on the intercepts in separate-
group models, which can cause the residual to deviate from the indepen-
dent and identical distribution (i.i.d.) assumption. Failure to address this
type of clustering effect may cause a serious downward bias in the esti-
mated errors, resulting in spurious findings of statistical significance for
the aggregate variable of interest (linkage to the iron and steel industry).
To deal with this problem, we control for both the inter- and intra- sectoral
variance in our OLS and FD regressions.
Finally, we carry out a robustness check by regressing the logarithm of
firms’ total output on their backward and forward linkages to the iron and
steel industry with the control of various inputs including labour, capital
and intermediate inputs. The purpose is to check whether the estimation
of firms’ TFP with the LP method may lead to any significant differences
in our regression results.
ESTIMATION RESULTS FOR THE BACKWARD AND FORWARD LINKAGE EFFECTS
Using Equations (6.2) to (6.5), we examine the relationship between
manufacturing firms’ productivity and their linkage to the iron and steel
industry at the aggregate level as well as by groups with different charac-
teristics as specified in the last section. The estimation results from both
the OLS and FD regression techniques with different model specifications
are presented in Tables 6.4 to 6.6.
Backward and Forward Linkages of the Iron and Steel Industry
Table 6.4 reports the estimation results at the national level obtained from
applying Equations (6.2) to (6.5). Columns (1) and (2) provide the OLS
estimates of the cross- industry linkages of China’s iron and steel industry,
with model I as the basic model specification controlling only for time-
specific, region- specific and industry- specific dummies, and model II as
the comparison model specification controlling for some additional firm-
specific and sector- specific factors such as the Herfindahl index, firms’
new product share, dummy for exporting, and foreign investment share.
The estimation results from both model specifications show that neither
M3021 - SONG 978184844658 PRINT.indd 118M3021 - SONG 978184844658 PRINT.indd 118 23/11/2012 14:5123/11/2012 14:51

the backward nor the forward linkages are statistically significant, which
seems to suggest that an increase in steel firms’ productivity had no signifi-
cant effects on the productivity of firms in the upstream and downstream
industries.
Although the OLS estimations could provide some useful information
on the cross- industry linkages of the iron and steel industry, they may suffer
from two potential problems: (1) the simultaneous bias problem whereby

120 The Chinese steel industry’s transformation
macroeconomic growth may generate firms’ productivity improvement in
both the iron and steel industry and its upstream and downstream indus-
tries; and (2) the omitted variable problem whereby some unobserved
firm- specific factors are closely correlated with firms’ productivity and
that influence the effects of their linkages with the iron and steel industry.
To deal with these problems, we run the first- differencing regressions
following Equations (6.4) and (6.5) and report the estimation results in
columns (4) and (5) of Table 6.4.
After eliminating the simultaneous bias and omitted variable problems,
we find that the iron and steel industry in China has significant positive
forward linkages to firms’ productivity in the downstream industries but
negative backward linkages to firms’ productivity in the upstream indus-
tries. Specifically, a 1 per cent increase in firms’ average productivity in
the three component sectors may tend to increase firms’ productivity in
the downstream industries by 4.2–4.4 per cent, while decreasing firms’
productivity in the upstream industries by 9.4–9.6 per cent. This finding
suggests that the improvement of firms’ average productivity in the iron
and steel industry will help to foster productivity improvements in the
downstream industries but harm that in the upstream industries.
This finding seems to contradict the view that a rapid development of
the iron and steel industry helps promote firms’ productivity in the whole
manufacturing industry of a country through its cross- industry linkages.
This is because as the iron and steel industry is developed, it is expected
that the industry generates more demand for the upstream industries and
provides higher- quality products (as intermediate inputs) to the down-
stream industries. However, our empirical results show that such an effect
in China is more likely to take place through the forward than the back-
ward linkages. In other words, an increase in the productivity of the iron
and steel industry only tends to improve firms’ productivity in the down-
stream industries, while decreasing firms’ productivity in the upstream
industries. A possible explanation for this phenomenon is that the iron
and steel industry in China has depended so much on imported iron ore
and other materials from international markets that the productivity of
domestic suppliers in the upstream industry has been negatively affected.
WHO CAN BENEFIT MORE? LARGE vs. SMALL FIRMS OR HIGH vs. LOW PRODUCTIVITY FIRMS
The estimates reported refer to the average impact of the iron and steel
industry on firms’ productivity in other manufacturing industries. A
further question one may ask is whether these results mask the heteroge-
M3021 - SONG 978184844658 PRINT.indd 120M3021 - SONG 978184844658 PRINT.indd 120 23/11/2012 14:5123/11/2012 14:51
Backward and forward linkages of the Chinese steel industry 121
neity of the linkage effects across firms with different characteristics. To
answer this question, we now split our sample into subgroups according to
firms’ operational size and productivity level and re- estimate the linkage
effects of the iron and steel industry with different samples based on
Equations (6.2) to (6.5). The estimation results from the FD regressions
are shown in Tables 6.5 and 6.6.
As shown in Table 6.5, the estimated linkage effects from the FD regres-
sions with the large firms and with the medium and small firms show that
medium and small firms in the downstream industries are more likely
to benefit from the forward linkages of the iron and steel industry than
large ones. A 1 per cent increase in the industry’s average productivity
may increase the productivity of medium and small firms by 4.4–4.6 per
cent, which is around twice that for large firms (at 2.5–2.7 per cent). This
phenomenon may be explained by the fact that most small and medium
firms in the Chinese manufacturing sector had already been privatized as
part of the industrial transformation. These privatized firms are more flex-
ible in choosing their input mix and thus likely to make more use of the
innovation or positive externalities passing through the upstream iron and
steel industry to improve their own productivity. In terms of the negative
backward linkages, there is no significant difference for firms with dif-
ferent operation sizes. As shown in Table 6.5, a 1 per cent increase in the
average productivity of the iron and steel industry may decrease produc-
tivity for all sized upstream firms by 9.1–9.5 per cent. This finding suggests
that such a negative backward linkage is likely to be independent of firms’
operational scale.
The next question we may ask is whether the heterogeneity in firms’
productivity affects the potential gains in productivity from the iron and
steel industry through the backward and forward linkages. Table 6.6
presents the estimation results from the FD regressions for firms with
low (x , 25 per cent), medium (25 per cent , x , 75 per cent) and high
levels of productivity, where x is the measure of productivity, relative
to the full sample. Two interesting findings are apparent here. First, the
positive forward linkage effects of the iron and steel industry decrease with
changing levels of firm productivity. A 1 per cent increase in the average
productivity of the iron and steel industry may increase the productivity
of firms with low, medium and high levels of productivity by 5.3, 4.1 and
3.4 per cent, respectively. This result implies that firms with relative low
productivity are likely to benefit more from the forward linkages with the
iron and steel industry. Second, the negative backward linkage effects are
more severe for firms with a high level of productivity than for those with
medium and low productivity. A 1 per cent increase in the average produc-
tivity of the iron and steel industry may decrease the productivity of firms
M3021 - SONG 978184844658 PRINT.indd 121M3021 - SONG 978184844658 PRINT.indd 121 23/11/2012 14:5123/11/2012 14:51
122 The Chinese steel industry’s transformation
with low, medium and high levels of productivity by 8.8, 8.1 and 16.9 per
cent, respectively. This result implies that productivity improvements in
the iron and steel industry are more likely to negatively affect those firms
with relative high productivity in the upstream industry.
The above findings seem to suggest that firms with low productivity in
the Chinese manufacturing sector may benefit more from the backward
and forward linkages of the iron and steel industry. It remains to be seen
how the ongoing reform in the iron and steel industry or even in the whole
industrial sector could further strengthen the cross- industry linkage of the

124 The Chinese steel industry’s transformation
iron and steel industry with both the upstream and downstream industries
to the extent that the improved productivity of the iron and steel industry
spreads more positively to the other sectors of the economy.
ROBUSTNESS CHECKS
To check whether the above estimation results are sensitive to our specific
productivity estimation method, we have redone all estimations with the
logged output as the dependent variable (with the control of the three
inputs including labour, capital and intermediate inputs). The results show
that the new estimation results with the logged output as the dependent
variable are generally consistent with those with the estimated TFP as the
dependent variable, except that the standard errors of most coefficients
become larger. This result suggests that our initial estimation on the back-
ward and forward linkages of the iron and steel industry is stable.
CONCLUSIONS
Using the data from the Annual Manufacturing Enterprise Census, this
chapter has examined the cross- industry linkages of the iron and steel
industry in the Chinese manufacturing sector from an empirical perspec-
tive. After controlling for the potential endogeneity problems, we found
that a rapid increase in average productivity of the iron and steel industry
can promote firms’ productivity in the downstream industry but harm
firms’ productivity in the upstream industry, which can be partly explained
by the high degree of dependence of China’s iron and steel industries on
imported materials such as iron ore, which may negatively affect domestic
suppliers, especially the better- performing ones. This import substitution
policy has been implemented primarily because domestic supplies are
inferior in terms of both quantity and quality.
When firms’ heterogeneity in operational size and productivity are
considered, our results have shown that medium and small firms with low
productivity are more likely to benefit from the further development of
the Chinese iron and steel industry. A policy implication would be that
China should try to deepen the ongoing industrial reform in the iron and
steel industry as well as in the whole industrial sector in order to further
strengthen the cross- industry linkages of the iron and steel industry with
both the upstream and downstream industries. This would allow the
improved productivity of the iron and steel industry to spread more posi-
tively to the other sectors of the economy.

126 The Chinese steel industry’s transformation
APPENDIX
Ordinary least squares (OLS) is inappropriate for estimating the impacts of
labour and capital on productivity, since they are factors of production and,
as such, should be treated as endogenous. Olley and Pakes (1996) (OP), fol-
lowed by Levinsohn and Petrin (2003) (LP), point out that inputs like capital
should be considered endogenous, since management chooses their levels or
usage rates based on cost and productivity considerations that are observed
by the producer but not by the econometrician. Productivity estimates may
be biased if the endogeneity of input choice is not taken into account.
To address this concern, we employ a semi- parametric estimation pro-
cedure suggested by LP. Compared with the OP approach, LP allows for
firm- specific productivity differences that exhibit idiosyncratic changes
over time, and use intermediate inputs rather than long- term capital invest-
ment to proxy for unobserved productivity. We follow the LP method for
two reasons: (1) a special feature of firms in China is that their investment
behaviour is highly influenced by government policy (such as policy loans
provided by the state- owned banks to SOEs), so that investment might
not be monotonic with respect to productivity; and (2) our data cover
only four years, which is not long enough for firms to make capital adjust-
ments, especially in regard to long- term investments in physical structure
and machinery. More specifically, we assume that the production takes the
form of a Cobb–Douglas production function whose natural- logarithmic
form after taking the first- order differentiation is:
yit 5 bc 1 bllit 1 bkkit 1 bmmit 1 .it 1 uit, (6.A1)
where bc measures the mean efficiency level across firms and over time,
.it represents firm- level productivity, and uit is a component following
an independent and identical distriubtion, which represents unexpected
deviations from the mean due to measurement error, unexpected delays
or other external circumstances. The three components are combined to
determine the time- specific and producer- specific outputs.
In order to estimate Equation (6.A1), we further assume that capital is
a state variable that is affected only by current and past levels of unob-
served productivity (.it) and is monotonic with respect to the intermediate
inputs. We define:
vit 5 gt(kit,.it
)
(t 5 1, . . ., T) , (6.A2)
where vit is a vector of proxy variables (that is, intermediate inputs) and
g(∙,∙) is time- invariant. Thus, the choice of intermediate inputs depends on
M3021 - SONG 978184844658 PRINT.indd 126M3021 - SONG 978184844658 PRINT.indd 126 23/11/2012 14:5123/11/2012 14:51
Backward and forward linkages of the Chinese steel industry 127
capital and productivity. Provided that the choice of intermediate inputs
is strictly increasing in productivity and conditional on capital, the rela-
tionship between vit and .it can be inverted. Thus, we have .it 5 ht(kit,vit
) ,
where ht(.,.) 5 g21
t( . , . ) . Substituting this information into Equation
(6.A1), we have:
yit 5 b0 1 bllit 1 bkkit 1 bmmit 1 ht(kit,vit
) 1 uit. (6.A3)
Estimation of Equation (6.A3) is carried out in two stages. In the first
stage, we define �(mit,kit) 5 b0 1 bkkit 1 bmmit 1 ht
(vit,kit) (in LP). Thus,
the OLS method can be used to estimate:
yit 5 bllit 1 �(vit,kit) 1 uit, (6.A4)
where �( . , . ) is approximated by a higher- order polynomial in vit and
kit (including a constant term). Estimation of Equation (6.A4) results in
a consistent estimate of the coefficients on labour. In the second stage,
assume that productivity follows a first- order Markov process, that is,
.it11 5 E(.it11 0 .it) 1 xit11, where xit11, representing the news compo-
nent, is assumed to be uncorrelated with productivity and capital in period
t 1 1. Thus, the estimation algorithm can be written as:
E [yit11 2 bllit11] 5 b0 1 bkkit11 1 E(.it11
0.it) 1 xit11 1 uit11,
(6.A5)
where E(.it110.it
) 5 q(�it 2 bkkit 2 bmmit) follows from the law of
motion for the productivity shock. As the first stage of the estimation
procedure has used a higher- order polynomial expansion in �̂it 2 b̂kkit
or �̂it 2 b̂kkit 2 b̂mmit to approximate g(∙,∙), the capital coefficients can
then be obtained by applying non- linear least squares (NLS) to Equation
(6.A6):
yit11 2 bllit11 5 b0 1 bkkit11 1 bmmit11 1 q(�it 2 bkkit 2 bmmit)
1 xit11 1 uit11. (6.A6)
By using the LP method, we can obtain accurate production function
estimates that can be used in turn to estimate domestic productivity.

7. China’s shift from being a net importer to a net exporter of steel and its implications
Haimin Liu and Ligang Song
INTRODUCTION
China for a long time prior to the 1990s was an importer of steel products,
reflecting the fact that its domestic supply could not meet its demand
in terms of both quantity and quality of steel products. From 1990, the
country began to export steel products, but in the following 15 years
remained a net importer. With the rapid growth of its exports, and the
local industry’s increasing ability to compete with imports, China became
in 2005 a net exporter of steel products (see Figure 7.1). The massive
increase in China’s steel exports since then reflects the fact that the coun-
try’s underlying comparative advantage has begun shifting from labour-
intensive to capital- intensive production, which coincides with the mid
phase of industrialization characterized by the level of China’s per capita
income in the second half of the first decade of the twenty- first century.
Such an increase in exports of steel products from China has caused
some trade friction, especially with the industrialized countries of Europe
and North America. Since China surpassed the United States to become
the world’s largest consumer of steel products in 2001 and has remained
the largest consumer of steel since then, one may ask why China has
shifted from being a net importer to a net exporter of steel products and
what the implications of such a shift might be for both China and its
trading partners in terms of economic restructuring. The purpose of this
chapter is to address this question and to discuss some implications associ-
ated with the shift.
To do so, we need to ask the following questions: On w h a t basis has
China become the world’s largest exporter of steel products? What
are China’s comparative and competitive advantages in producing and
exporting steel products? Will this comparative advantage endure, given
the current trend of rising production costs including labour and energy

costs and the need for structural change in response to the requirement for
addressing climate change in China? Why and how does the Chinese gov-
ernment try to control the exports of steel products? What does the future
hold with regard to China’s role as an exporter of steel products?
PATTERN AND TREND OF CHINA’S EXPORTS OF STEEL PRODUCTS
China developed a fairly strong base for its steel industry development
during the period of the central planning system (1950–76). However, as a
developing country, China’s steel industry has historically lagged behind
the global frontier in terms of its level of technology and equipment used
in production. As a result, despite a large quantity of steel being produced,
China was consistently a net importer of steel products prior to 2005
and relied heavily on importing high- quality steel products in particular
from Japan. During the period 1978–2004, China imported a total of 495
million tonnes of crude steel (equivalent),1 accounting for 17 per cent of
its apparent consumption of steel. China’s net imports of steel reached
369 million tonnes during the same period. The large quantity of China’s
demand for imported steel was extremely beneficial for the international

The shift from net importer to net exporter 131
steel industry especially during the economic downturns of the OECD
countries in 1993 and 2003, respectively.2
Since 2004, China’s steel exports have increased at a faster rate than its
steel production, while steel imports have fallen continuously and have
consolidated at the level of about 20 million tonnes, which was maintained
during the period before 2000. In 2005, China ended its decades- long
history as a net importer of steel, while simultaneously replacing Japan as
the largest exporter of steel in the world in the period 2006–08.3 Despite
the sharp decrease in production and trade resulting from the global
financial crisis (GFC) in 2008/09, China’s steel trade has kept a favourable
balance in volume terms (Figure 7.1 and Table 7.1).
To measure a country’s dependence on exports of steel products, one
can use the steel export ratio, defined by export/production. China’s steel
export ratio reached its peak level at 15 per cent in 2007, which is far from
the highest as compared with many other steel- producing countries. For
example, in the same year, the steel export ratios of Taiwan, Canada,
Russia, Ukraine, Japan and South Korea all greatly surpassed China’s
(Figure 7.2). However, what is significant for China is the fact that the
absolute scale of China’s steel production (the denominator) reached 37
per cent of total w o r l d steel o u t p u t in that year. Due to the large quantity
of steel being produced in China, any additional increase in the export
ratio can have a destabilizing impact on the global market for steel.
The main destinations of China’s steel exports include its neighbouring
countries and regions such as South Korea, the ASEAN- 10 countries,

132 The Chinese steel industry’s transformation
Hong Kong, Macao, Taiwan, India, the Commonwealth of Independent
States (CIS) and Middle Eastern countries. Among them, South Korea
and the ASEAN- 10 are the largest destinations for China’s steel exports.
In 2010, China’s steel exports to these countries accounted for 67 per cent
of China’s total steel exports (see Figure 7.3). Notably, China has also
exported steel products to both the European Union and North American
markets, as well as to markets such as the Middle East and India. Such
diversification of exporting destinations reflects the fact that the Chinese
steel industry is gaining competitive advantage as well as advantage in
terms of quality of products on world markets. It is therefore not surpris-
ing that the sudden surge in China’s steel exports has generated consider-
able anxiety in the world steel industry.
Chinese enterprises have an obvious price advantage in international
markets, but they have had a significant impact on similar industries and
enterprises in importing countries, which can easily trigger trade protec-
tionism in these countries. China has become the major target country of
anti- dumping suits around the world. According to the statistics released
by the WTO, between 1995 when the WTO was founded and June 2008,
there were 3305 anti- dumping investigations launched worldwide, of
which 640 cases were against China, or nearly a fifth of all cases (Li and
Song, 2011). Some countries such as the United States took anti- dumping
measures against the imports of steel products from China. Figure 7.3
reports the major destinations of China’s steel exports in 2010 (per cent).

The shift from net importer to net exporter 133
COST FACTORS AND THE COMPETITIVENESS OF CHINA’S STEEL INDUSTRY
China’s shift from being a net importer to a net exporter of steel has
been fundamentally determined by the cost factor, which in turn reflects
the changing pattern of China’s underlying comparative advantage.
Consistent with this changing pattern of comparative advantage, the
pattern and composition of China’s exports have also changed over
time – from the predominant reliance on primary goods such as petro-
leum and agricultural products at the beginning of the reform period; to
labour- intensive products such as textiles and clothing during the first
two decades of reform; further to capital- intensive products such as steel,
machinery and automobiles in the current phase of industrialization;
and increasingly to technology- intensive products such as some high-
tech equipment, bio- products and green technology (Li and Song, 2011).
This dynamic change in China’s comparative advantage in producing
and exporting capital- intensive goods has made the production of these
outputs such as steel products more competitive on international markets
through taking advantage of relatively low costs.4

134 The Chinese steel industry’s transformation
competitive status on international markets through lowering the costs of
production and enhancing technological change in the industry. There are
two main factors which contribute to the industry’s increasing competitive
advantage in producing and exporting steel products. The first one is its
firms’ notable advantage in adopting low costs of production, especially
with respect to the low cost of labour; the other is the industry’s improved
productivity since the late 1990s, resulting from industry reform and tech-
nological change.
China’s steel industry undeniably enjoys the benefits from low labour
costs relative to its competitors. Coinciding with the period of reform,
China went through a phase of development during which it has benefited
tremendously from the rapid pace of urbanization, when cheap labour
flowed into the industrial sector from rural areas. The seemingly unlimited
supply of labour kept industrial wages at a relatively low level, thereby
lowering the costs of production, raising aggregate labour productivity
and adding to the competitiveness of the Chinese industries including the
steel industry. Over the same period, China also benefited from the ‘demo-
graphic dividend’ whereby the large share of the population that was of
working age contributed positively to the supply of labour and national
savings, thereby further strengthening the competitiveness of Chinese
industries. For example, the steel industry’s labour productivity, measured
by the average steel production per steel worker, was 550 tonnes for large
and medium steel enterprises in 2010, up from around 100 tonnes at the
end of the 1990s. Despite the progress being made in raising the labour
productivity over this period, the current average level of productivity in
China’s steel industry in 2010 was equal to only one half of the productiv-
ity level of large foreign steel mills. However, the average wage of Chinese
steel workers was still much lower, at around 20 per cent of levels prevail-
ing in advanced countries. The net effect was that Chinese steel- makers’
labour costs per unit of production were still about 50 per cent lower than
their American and European competitors’. In this regard, the steel indus-
try is not an outlier, as this comparison of costs of production is rather
consistent across the industrial sectors in China.
Similar to the situation in other industrial sectors, the improvement in
productivity in the steel industry has been due mainly to the reform and
industrial restructuring carried out as part of the overall industrial sector
reform. These reform measures include market entry, internal restructur-
ing such as shareholding reform, privatization, corporate government
reform and openness to trade. As a result, China’s steel industry not only
has increased its scale of production, but also has made rapid inroads into
the productivity gap which existed between firms in China and the world’s
most technologically advanced producers.

The shift from net importer to net exporter 135
Increased competition has prompted firms to invest more in production
equipment, to increase greater energy efficiency, to enhance labour pro-
ductivity and to improve product quality. For example, within a period
of less than ten years, China’s ratio of continuous casting in total steel
production rose from 85.3 per cent in 2000 to 97.4 per cent in 2009, which
is above the world average of 94.1 per cent.5 Furthermore, technological
upgrading has enabled the average intensity of energ y consumption for
members of the China Iron and Steel Association (CISA)6 to fall from 885
kg of coal equivalent (kgce) in 2000 to 605 kgce7 per tonne of crude steel
in 2010, which is below the global a v e r a g e level of intensity of energy con-
sumption.8 Accordingly, the energy consumption in the main production
processes of these firms also decreased considerably (Table 7.2). These
efficiency gains, resulting from the industrial reform, increased competi-
tion and technological progress, added to the strong competitiveness of
the industry driven by the relatively low cost of production, especially with
respect to the cost of labour.
The industrial reform has also led to a fall in fixed expenses as a pro-
portion of the total sales for the industry. These fixed expenses include
the administrative, financial and operational costs (including marketing).
Therefore, the reduction of these expenses is indicative that the industry
has improved its administrative, financial and operational efficiency
(Figure 7.4). The data show that of the three measurements, the admin-
istrative costs fell most steeply, decreasing from 8.9 per cent of total sales
in 2000 to 2.9 per cent in 2010. This is significant, as high administrative
costs were associated with most of the state- owned enterprises in the past.
While the financial expenses increased (which may reflect the increasing
costs of inputs), the costs of marketing fell over this period, which is a clear
indicator of how firms have improved their level of efficiency in selling
their products.
Another source of competitiveness of the steel industry in China could
be that a considerable number of steel enterprises, especially small and

136 The Chinese steel industry’s transformation
medium ones, have violated state regulations by improperly cutting the
expenditures required for environmental protection. This is of course not
an implicit subsidy to the firms provided by the central government, as
policy- makers at the central level are keen to stamp out such inopportune
behaviour. The problem lies at local/provincial government levels where
laxity in implementing the state environmental regulations arises owing to
the consideration that implementing such regulations may put local firms
in a disadvantageous position by increasing the cost of production. This is
therefore an area where local governments are operating in conflict with
the national interest. Generally, China’s steel industry has been rather
backward in terms of reducing emissions of carbon monoxide and dust
and their efforts in controlling sulphur dioxide only began at the begin-
ning of the current century, while in developed countries the old pollution
problems have been solved and much consideration is given to the treat-
ment of carbon dioxide and dioxins. It is likely that China’s performance
in this area will fall short of Beijing’s goals on reduction of emissions as
long as provincial governments act to protect local interests.
Furthermore, there are two policy factors that have played a role in
determining the exports of steel products by Chinese firms. First, a com-
monly cited factor is that the yuan has been undervalued, which gives the
Chinese firms a competitive edge in exporting their products to world
markets. In examining whether this perception is correct, one needs to
look at the long- term trends in changes in currencies and the level of
per capita income. Figure 7.5 portrays such a relationship, using cross-
country data, which show that there is in general a positive correlation
between the appreciation of a country’s currency and the increases in its

level of per capita income. In the case of China, the value of its currency
versus its purchasing power parity (PPP) rate in 2008 (0.55) was basically
consistent with its level of per capita income (US$3259) in PPP terms as
compared with a PPP of unity for the United States with per capita level
of income reaching US$47 440 in 2008. Figure 7.5 also suggests that the
exchange rate of the yuan with the US dollar will not rise to 100 per cent
of its PPP level before China becomes a high- income country. Even were
the yuan to rise to this level, China, as a low- income country (in per capita
terms), would continue to enjoy its labour cost advantages, as the average
wage of Chinese steel workers is unlikely to catch up with those in devel-
oped countries in the foreseeable future. Furthermore, the Chinese steel
industry’s productivity will continue to converge towards the level of its
competitors in those advanced countries as a result of the ongoing reform
and technological progress. This will allow Chinese steel firms to continue
to enjoy the advantage of catching up with the most advanced technology
applied in the developed countries.
The second factor in determining the level of Chinese exports of steel
products is China’s demand for energy and resources, which has been
rapidly rising owing to the country’s rapid economic growth since 2003. In
response to this growing resource demand, China has adopted measures
to encourage imports and restrict exports for raw materials. In 2004, for

138 The Chinese steel industry’s transformation
the first time, the Chinese government applied the differentiated export
rebate of value added tax (VAT) as a policy instrument to restrict exports
of resource products. The VAT rebate rates for most primary products
exported were reduced and for some products they were eliminated com-
pletely. Further, in November 2006 China started to impose export tariffs
on some resource products on which the VAT rebate had been reduced to
zero, including pig iron, ferroalloy, coke, semifinished steel and common
long steel products. For example, a 40 per cent tariff was imposed on
coking coal exports without any rebate of VAT. This policy change seems
to have increased the export cost of coking coal by at least 40 per cent,
thereby disadvantaging foreign steel- makers using Chinese coking coal.9
In response to this policy change, steel- makers in America and Europe
claimed that taxing exports of coke equated essentially to ‘government
subsidies’ to the Chinese steel- makers as steel- makers in other countries
faced much higher costs of importing coke from China. The steel- makers
in those developed countries insisted that were there no subsidies then
China’s steel products would be far less competitive in international steel
markets. For example, a 2007 report from the German Steel Federation
claimed: ‘Unfair prices of this extent are principally possible because
China subsidises its state- owned steel companies, resulting in massive
overcapacities there’.10 In the same year, a report commissioned by a US
lobby group claimed that the Chinese government had subsidized the steel
industry by the equivalent of US$52 billion.11 In January 2009, a similar
report on behalf of the EUROFER (European Confederation of Iron and
Steel Industries) claimed that Chinese steel products would be unable to
enter the European market without government subsidies.12
It is true that, prior to China’s accession to the WTO at the end of 2001,
the Chinese government provided subsidies of various kinds to the then
state- owned enterprises including steel- makers. However, the Chinese
government took important steps in reforming the system of subsidies in
relation to the state- owned enterprises as part of its efforts to comply with
the requirements of the WTO prior to its accession. Since the accession, the
government has removed all of the direct subsidies to its enterprises, and
later unified company income taxes, which now apply to all kinds of firms,
including foreign firms operating in China. Even though there have been
no direct subsidies provided to the firms by the government, Chinese firms
may gain some competitive advantages from the partially reformed factor
market system, which allows the firms to utilize some of the key resources
such as energy and materials at below- market prices (Huang and Wang,
2010). As for the steel sector, the study by Liu (2008) shows that the key
factors underlying the strong competitiveness of the Chinese steel industry
come from the steel industry itself rather than the Chinese government.

The shift from net importer to net exporter 139
THE POLITICAL ECONOMY OF CHINA’S STEEL EXPORTS AND PROSPECTS
Although exporting steel products reflects the fact that China’s underly-
ing comparative advantage has been shifting towards the production of
capital- intensive goods at the stage of industrialization current at the time
of writing, there are certain concerns (including environmental concerns)
with respect to whether China should continue to follow this comparative
advantage in exporting steel products on a large scale to world markets.
These concerns reflect a key feature in the Chinese economy, namely that
there are distinct interests associated with steel firms, the industry and
the government, respectively, and those interests may not necessarily be
consistent with each other. These different interests will influence how the
trade orientation of the Chinese steel industry evolves over time.
First, China faces tremendous challenges associated with its economic
growth, both with respect to the use of resources and with regard to
reducing its intensity of carbon emissions. There were shortages of raw
materials and energy, and a great deal of environmental degradation
accompanying China’s rapid economic growth in the 30 years 1978–2008.
Steel production features heavy energy consumption, heavy pollution and
resource- intensive production, especially as the blast furnace/converter
process still dominates steel- making in China. Taking coal as an example,
according to British Petroleum (BP), China’s proven reserves of coal
were 114.5 billion tonnes at the end of 2008, which accounted for 13.9
per cent of the world’s total proven coal reserves. However, with a huge
amount of coal being produced annually, its R/P ratio (proven reserves/
output of the year) was only 41 years, comparing with the world average
of 122 years.13 With regard to the environment, China became the largest
carbon- dioxide- emitting country in 2007, with a continuous increase in
fossil fuel use. China’s steel industry created 8.3 per cent of the country’s
total industrial value added and provided 4.6 per cent of total industrial
employment, whereas it used 25.1 per cent of the total energy consump-
tion and generated 10–15 per cent of pollution in the total manufacturing
industries in 2007. Furthermore, the rapidly increasing exports of steel
products have led to the growth of industrial demand for iron ore and
other resources such as coking coal. This increasing demand in turn has
pushed up the iron ore prices in both international and domestic markets,
contributing to the continuous deterioration of China’s terms of trade.
Therefore, continuing to export steel products may be profitable for
steel- makers, but that will make it harder for the industry to reduce energy
and resource intensity and comply with the environmental regulations,
and for China to avert the deterioration of its terms of trade.

140 The Chinese steel industry’s transformation
Second, the increasing level of exports of steel products has reduced
the market pressure from excessive steel production capacity, resulting
in the failure of the Chinese steel industry’s efforts to control the rapid
expansion of its capacity. For example, had China not had net exports
of 40–50 million tonnes of steel annually over the period 2007–09, the
problem of excessive capacity in the industry could have been much
greater as those quantities of steel products would have had to be
absorbed in the domestic market. This could lower the domestic prices
for steel and squeeze the profit margins for the steel- makers. Considering
these adverse effects of exporting steel products, the Chinese govern-
ment has adopted measures to control steel exports, especially of low-
value- added products. According to Decree 35: China’s Steel Industry
Development Policy, issued by the National Development and Reform
Commission (NDRC) in July 2005, the basic role of the Chinese steel
industry was defined to ‘meet domestic demand’. From 2004, as men-
tioned earlier, the Chinese government adjusted tax regulations on steel
exports, reducing or abolishing the export rebate of VAT and collecting
tariffs on those exports.
The implementation of these regulations has made exporting costs
higher than the spot prices in the domestic market. The increased costs
vary for different steel products, but generally the costs are lower for
high- grade steel products and vice versa,14 depending on both suitable
rates of rebate and tariffs imposed on exports. For example, suppose 1
tonne of steel products is sold at the price of 5000 yuan excluding VAT or
5850 yuan including VAT15 in the Chinese domestic market. It could be
exported at the FOB (free on board) price of 5000 yuan if the VAT rebate
rate equals the collecting rate of VAT (complete rebate) and the exporter
would get similar profits as in domestic markets. If the VAT rebate is
different from the collecting rate of VAT by 10 per cent for example, the
exporter has to add 7 per cent at least, that is 350 yuan (5000 × 0.07) to the
original export price excluding VAT to get similar profits for the complete
rebate example. Furthermore, the price of FOB 5850 yuan (5000 1 5000
× 0.17) is equally beneficial to the exporter for steel products without any
rebate of VAT.
Let A 5 the price excluding VAT in the domestic market or export cost
under supposed export regulation of the complete rebate;
V 5 the suitable collecting rate of VAT;
Vr 5 the suitable rebate rate of VAT;
P 5 the actual export cost or actual export price (FOB), which
allows the exporter to get equal benefits as selling in domestic
markets.
Then, if there is a difference between V and Vr,
M3021 - SONG 978184844658 PRINT.indd 140M3021 - SONG 978184844658 PRINT.indd 140 23/11/2012 14:5123/11/2012 14:51
The shift from net importer to net exporter 141
P 5 A 1 P × (V − Vr),
and thus A 5 P − P × (V − Vr). (7.1)
Now let us add in the export tariff. As we know, the export tariff is
added only to the steel products without VAT rebate. Then let C be the
rate of suitable export tariff; P is the actual export cost for steel products
with zero VAT rebate, and C allows the exporter to receive equal benefits
to selling in domestic markets.
Then, P 5 A 1 P ÷ (1 1 V) × V 1 P × C,
P 5 A ÷ [1 − V ÷ (1 1 V) − C],
A 5 P × [1 − V ÷ (1 1 V) − C], (7.2)
D 5 an increase of export costs in amount 5 P − A,
E 5 an increase of export costs in percentage 5 P ÷ A − 1.
Based on the methods above, we quote the actual data of China’s export
costs or prices in 2010 to see how the different export policies affect the
export costs for different steel products (Table 7.3).
The results show that the policies adopted by the government have
been quite effective, be they in the form of either the VAT rebate or the
tariff imposed on steel exports as a measure to control exports of steel and
other resource products. Exports of plate, sheet, tube and pipe – so- called
‘high- grade steel products’ – have increased in both relative and absolute
terms, while the proportion of ‘low- grade products’ such as bar and wire
has decreased by half, and exports of semifinished steel have decreased to
almost zero in the five years to 2010. Certainly, the tendency to massive

142 The Chinese steel industry’s transformation
steel exports has, on the whole, been arrested by the measures adopted by
the government (Table 7.4).
CONCLUSIONS
The complication in discussing the trade orientation of China’s steel
industry lies in the fact that it is difficult to judge how much of the shift
to exports since 2005 is a phenomenon resulting from disequilibrium that
will be corrected over time. However, one thing is clear – China will not
end its imports of steel anytime soon, as it will continue to rely on import-
ing high- quality and high- value- added steel products which the industry
cannot produce while exporting low- to- medium- quality products to world
markets. The large increase in net exports of steel since 2006 was associ-
ated with many structural problems as identified in this chapter.
Looking to the fut u r e , the Chinese government may have no inten-
tion of forsaking its policy of controlling excessive steel exports in
consideration of the need for industrial restructuring, the reduction of
resource intensity use by the industry, and the impact on the environ-
ment. However, a big challenge in implementing this strategy is how the
Chinese government could bring steel production back into line with
domestic demand without relying too much on exports. The application
of VAT and the imposition of export tariffs do not provide a permanent
solution, because both policies go against the principle of free trade. One
alternative is to leave the market to decide how much steel output the
industry needs to produce and export. In so doing, it may benefit the

steel- makers in terms of obtaining short- term profits, but it may worsen
the long- term structural problems for the industry, including the impact
on the environment.
There are a number of structural factors operating which could for
the industry eventually align the balance between demand and supply of
steel products without excessive reliance on exports. They include con-
tinual upgrading of production capacity and the retirement of outdated
steel mills; reduction of the current fragmentation of the industry as the
industry continues to raise its concentration; increasing energy efficiency
through improved management and technological change; real exchange
rate appreciation characterized by both a stronger yuan and a rising price
level; higher wages consistent with the previous point; and more effective
enforcement of state environmental regulations.
NOTES
1. China both exports and imports finished steel as well as semifinished steel billet and slab, that is crude steel, which has to be rolled into finished steel before end use, and there is wastage of materials in the rolling process. For comparison across different years, we customarily convert the finished steel of imports and exports into crude steel by the average yield rates of rolling for every year. For example, the rate for 2010 is about 94 per cent, so, 1 tonne of finished steel is equivalent to 1.064 (1/0.94) tonnes of crude steel in that year.
2. In both years, China’s imports of steel peaked, exceeding 40 million tonnes. This represented an increase of 409.3 per cent and 47.6 per cent from the previous years, respectively.
3. According to World Steel in Figures (2008, 2009 and 2010 editions) published by the World Steel Association (WSA), Japan exported 34.6, 35.5 and 36.9 million tonnes compared with China’s exports of 54.6, 72.8 and 64.1 million tonnes in 2006, 2007 and 2008, respectively.
4. Another factor which determines the competitiveness of an industry on international markets is the quality of products.
5. WSA (2010). 6. CISA is a national steel industry organization. The members mainly consist of steel
production enterprises, which account for 80 per cent of national steel output. Some trading firms, equipment manufacturers and construction firms as well as consulting companies are also members of CISA.
7. This is an energy unit which is used customarily in China. 1 kgce 5 7000 kcal (kilocalories) 5 29.27 MJ (megajoules). To convert from coal equivalent to oil equivalent, the amount must be multiplied by 0.7.
8. According to WSA (2010), the indicator of average energy intensity was 18 GJ/tonne (GJ 5 gigajoule) steel (equal to about 615 kgce/tonne steel) for participants submitting their questionnaires for both 2007 and 2008.
9. However, China has become a net importer of coking coal since 2009. Therefore, the imposition of export tariffs on coke by the Chinese government may not significantly affect the steel firms in other countries, as coke users in other countries may get ‘cheap’ coke from other sources just as Chinese steel- makers do.

8. China’s iron ore import demand and its determinants: a time- series analysis
Yu Sheng and Ligang Song
INTRODUCTION
China’s rapid economic growth and openness to trade dramatically
increased its production, consumption and export (directly or indirectly)
of iron and steel products during the two decades between 1986 and 2006.
The expansion of China’s iron and steel industry has lifted its demand for
iron ore – one of the major inputs in the production of iron and steel – and
driven up world prices of iron ore in recent years. During the period 2000–
06, China’s consumption of iron ore increased from 292 to 908 million
tonnes with an average annual growth rate of 20.8 per cent. In 2006, the
total consumption of iron ore in China accounted for 57.6 per cent of total
world production. China has become the largest consumer of iron ore in
the world and a key driver underlying the resource boom since the mid
2000s. However, as pointed out by Garnaut (2012), the increase in import
share of iron ore supply by China over the past 20 years is likely to be a
unique occurrence – a source of growth in imports that will not be there to
any significant degree in the future.
The dramatic increase in demand for iron ore in China has not only
encouraged the domestic suppliers to boost their production, but also caused
the rapid growth in Chinese imports from the international market. During
the period 2000–06, China’s total imports of iron ore increased from 70 to
326 million tonnes, giving an average annual growth rate of 29.3 per cent –
8.5 percentage points higher than the annual growth rate of total demand
and 11.9 percentage points higher than that of the demand from domestic
production. China’s dependency on imported iron ore (or the ratio between
imports and domestic production) reached 56.1 per cent in 2006. Given the
relatively constant world supply of iron ore, China’s high dependency ratio
implies that its increasing demand for iron ore from the international market
has exerted upward pressure on the world market price (Figure 8.5).

146 The Chinese steel industry’s transformation
China’s increasing demand for iron ore raises two important issues.
First, what are the main driving forces and long- term trends behind
China’s increasing demand for iron ore from the international market?
Second, will world production of iron ore meet the future demand of
China’s expanding steel industry, and how will the world price of iron ore
change over time? Answering these questions is the purpose of this chapter.
This chapter applies time- series analysis to the industry- level data for
the period 1960–2005 to examine the trend of China’s imports of iron ore
from the international market and its determinants from a demand per-
spective. The analysis provides a useful context within which some policy
issues could be addressed. For example, one issue is whether government
intervention in imports of iron ore from the international market, through
restricting exports of pig iron and steel products by domestic steel- makers,
and imports of iron ore by small and medium firms, is necessary or not for
increasing the efficiency of China’s iron and steel industry, improving envi-
ronmental protection and stabilizing the world market price of iron ore.
There are three key empirical results: (1) The major driving force behind
China’s rapidly increasing import demand for iron ore is the increas-
ing domestic consumption of iron and steel products, and the demand
is generally price- inelastic, especially in the long run. (2) There exists a
significant substitution relationship between domestically supplied and
imported iron ore, but the quality (or richness) of domestic iron ore is
negatively related to the quantity of imports, suggesting that China’s
iron ore imports have played an important role in compensating for the
inadequacy of the domestic supply of iron ore in terms of both quality and
quantity. (3) Exports of pig iron and steel products do not have a signifi-
cantly positive relationship with the imports of iron ore in China, implying
that restricting exports of steel products might not be conducive to reduc-
ing the pressure on imports of iron ore.
CHINA’S IRON ORE IMPORTS: 1960–2006
China has been importing iron ore from the international market since
1960, despite the fact that the Chinese economy was operating under
a planned system between 1960 and 1978. However, the quantities of
imports had been rather small until the mid 1980s when they started to
increase steadily. In the two decades 1985–2006, China’s import of iron
ore increased rapidly from 10.1 million tonnes to 326.3 million tonnes, and
its domestic supply of iron ore also increased substantially over the same
period (Table 8.1). Figure 8.1 shows the changes in the shares of China’s
iron ore production and trade in the world total. After more than ten years

The iron ore import demand 149
by the massive construction of infrastructure resulting from the rapid
and unprecedented pace of urbanization and the change in industrial
structure towards capital- intensive industries, was the main driver for
China’s increasing demand for iron ore during the two decades to 2006.
It is agreed in the literature that there is a strong correlation between
economic growth (represented by changes in a country’s GDP per
capita) and iron and steel consumption in the process of industrialization
(Chenery et al., 1986), and China provides no exception. Figure 8.2 shows
the relationship between GDP per capita calculated at constant 2000
US dollar prices, and the apparent consumption of crude steel in China
during the period of 1960–2006. With rapid economic growth due to
continuous industrialization, urbanization, openness to trade and other
macroeconomic economic reforms, China’s GDP per capita increased
significantly in the 1990s and 2000s with an average annual growth rate
of 8.34 per cent (between 1997 and 2006), more by far than the world
average at 2.67 per cent. This drove up the total consumption of iron and
steel products. In 2006, China’s total apparent consumption of crude steel
was 387.93 million tonnes, accounting for 34.6 per cent of the total world
consumption of crude steel. The dramatic increase in China’s demand for
steel products boosted its demand for iron ore from both domestic and

150 The Chinese steel industry’s transformation
Second, the insufficient and low- quality domestic supply of iron ore has
been unable to meet the requirements of China’s rapidly expanding iron
and steel industry. Although China’s own reserves of iron ore are plentiful
in quantity and it has been ranked as one of the largest iron ore producers
in the world, domestic supplies of iron ore in terms of both quantity and
quality have been insufficient for meeting the increased demand from the
production of iron and steel products, especially those of high quality.
Figure 8.3 shows world iron ore production by region in 2005. China’s
crude iron ore production reached 420.5 million tonnes in 2005, account-
ing for 26 per cent of the total world output and making it the largest
producer of iron ore in the world. However, there was still a large gap of
275.3 million tonnes (accounting for around 57 per cent of China’s total
consumption) between demand and supply, making it necessary to import
iron ore from overseas sources to meet the shortfall.
In terms of the quality of domestic supply of iron ore, Figure 8.4 shows
the explored reserves of iron ore by richness in China in 2003. From the
total reserves of 57.7 billion tonnes, 85.8 per cent was relatively poor
quality, with iron content of less than 40 per cent, and only 1.9 per cent
was relatively rich, with iron content of more than 48 per cent. The average
ferrous content of China’s iron ore reserves was less than 33 per cent. This
suggests that the quality of China’s domestic supply of iron ore was largely
insufficient for the production of high- quality steel, so that utilizing its

The iron ore import demand 151
own reserves requires iron ore to be further processed, involving higher
costs in production. As a consequence of the need to supplement dom-
estic iron ore supplies in both quantity and quality owing to the increasing
demand from production, it is not surprising that China’s imports of iron
ore from the international market have been rising over time.
Third, it is the relative price advantage of iron ore in the international
market over that in the domestic market which shifts China’s demand for
iron ore from its domestic market to the international market. From the
production perspective, demand for iron ore is generally inelastic with
respect to its price for three reasons (Chang, 1994): (1) Iron ore input
accounts for only approximately 5 per cent of steel production costs (Tex
Report, 1988). Therefore, the costs of steel production are likely to be
largely unaffected by small increases in the price of iron ore. (2) There is
no substitute for iron ore in the production of steel in integrated steel mills,
and as such, steel producers face little room for adjustment to the product
mix. As a result, producers are unlikely to significantly alter quantities of
iron ore given a short- term change in its price. (3) Steel production plants
are, in general, highly specific and capital- intensive operations; since maxi-
mizing the utilization of capital can help achieve significant economies
of scale, normal operation aims to sustain high capital utilization. Given
that decreasing capital utilization due to an increase in iron ore prices
would significantly affect unit steel costs of output, demand for iron ore
may not alter significantly following a change in price. Given the inelastic
demand for iron ore, the relative prices on the domestic and international

152 The Chinese steel industry’s transformation
markets have thus played an important role in determining China’s iron
ore imports.
Figure 8.5 shows the nominal and the real price of iron ore on the inter-
national market during the period 1960–2007. Although the nominal price
continued to increase, the real price has been falling since the mid 1970s
owing to the depreciation of the US dollar and the reduction of interna-
tional transportation fees (except for the five years to 2007). Combined
with the increasing costs of domestic supply, this has encouraged China’s
enterprises to shift their demand for iron ore to the international market
since they can reap obvious savings in the cost of steel production by
importing the high- quality ore.1
We have now summarized the three important reasons for China’s rapid
increase in iron ore imports: domestic demand, relative price and domestic
supply. Next we examine how those factors affect China’s iron ore imports
by estimating an import demand function with the aggregate time- series
data.
THE TIME- SERIES MODEL OF INTERNATIONAL DEMAND AND DATA
The estimation of an import demand function is considered to be sufficient
to analyse China’s international demand for iron ore. Following Chang
(1994) and Tcha and Wright (1999), we specify the log–linear empiri-

demand, relative price and domestic supply, in affecting China’s iron ore
imports, as shown in Equation (8.1):
ln IMt 5 b0 1 b1 ln DACt 1 b2 ln RPt 1 b3 ln DSt 1 b4 ln IDRt
1 b5 ln EXPIt 1 b6 ln EXSTt 1 gD90 1 et (8.1)
where IMt is China’s iron ore import quantity at time period t; DACt is
the domestic apparent consumption of crude steel at time period t; RPt
is the real price of iron ore in the international market in constant 2000
US dollars; DSt is China’s domestic supply of crude iron ore; and IDRt
is the ferrous content of domestic iron ore supply at time period t. D90 is
a dummy variable equal to 1 if t $ 1990 and 0 otherwise, which is used
to capture the different trend of China’s iron ore imports after 1990.
Differing from previous studies, we also put China’s exports of pig iron
(EXPIt) and steel products (EXSTt) into the regression to identify the
impact of China’s exports of iron and steel products on its demand for
iron ore from the international market. Finally, et denotes the residual and
all variables are given as natural logarithms; bs are coefficients. Equation
(8.1) defines China’s imports of iron ore as a function of its steel consump-
tion, the real price in the international market and the domestic supply (as
a substitute). The basic logic behind the equation comes from the demand
function, which emphasizes that demand for iron ore from the interna-
tional market in China is determined by its consumption, price, domestic
substitute and exports of iron and steel products.
The data used for our estimation are the aggregate time- series data for
China during the period 1960–2005. The variables, such as China’s total
import of crude iron ore from the international market (IMt); the domestic
apparent consumption of crude steel (DACt); China’s domestic supply of
crude iron ore (DSt); and China’s exports of pig iron (EXPIt) and steel
products (EXSTt) are defined as the same as those in China Iron and Steel
Industrial Data Compression for 50 Years (CISA, 2004). The data for those
variables before 2000 are taken from China Iron and Steel Industrial Data
Compression for 50 Years and those after 2000 come from China Iron and
Steel Statistical Yearbook (CISA, various issues). IDRt is defined as the
ratio of the amount of iron extracted from domestic iron ore over the total
amount of crude iron ore produced domestically. The real prices of iron
ore in the international market (RPt) are defined as the spot market prices
of iron ore obtained from the Australian Commodity Statistics (ABARES,
2006), which are deflated using the US consumer price index (CPI) taken
from the WDI online database.

154 The Chinese steel industry’s transformation
Since there might exist autocorrelation in the residual (et), the estima-
tion of Equation (8.1) with the ordinary least squares (OLS) method
may suffer from the time- series problem. Thus, the Dickey–Fuller (DF)
test for unit root of main variables and for the residual of some linear
combination of those dependent variables should be made to identify
the integration and cointegration relationship among those variables.
Table 8.2 shows the DF test results for each variable, and it suggests
that all variables are the first- order integrated. This can also be shown
in Figure 8.6, since all the first- order differences of those variables are
stable.
Table 8.3 shows the results of DF tests for the cointegration relation-
ship between the dependent and independent variables for both the first-
difference and the error correction models. The results show that the null
hypothesis that there exists no cointegration between those variables is
rejected for both cases at the 1 per cent significance level. This suggests
that both the first difference and error correction models can be used to
estimate the relationship between China’s imports of iron ore and their
determinants over time.
Thus, the two empirical models can be specified as below:

158 The Chinese steel industry’s transformation
correction models show that four key factors have played different roles in
determining the outcomes.
First, the domestic consumption of iron and steel products is the most
important determinant of China’s imports of iron ore from the interna-
tional market. As expected, Table 8.4 shows that the coefficients of the
domestic consumption of crude steel in both models are positive and
statistically significant at the 1 per cent level, implying that the domestic
consumption of crude steel is positively related to the imports of iron ore
in China. This implies that domestic consumption is a major driving force
in China’s iron ore imports, as other factors, such as price and domestic
substitution are well controlled. Moreover, the short- and long- run elas-
ticities of China’s imports of iron ore from the international market with
respect to the changes in domestic consumption of crude steel can be pro-
jected from the estimated coefficients of the error correction model, which
are 3.26 and 4.33, respectively. This suggests that a 1 per cent increase in
domestic consumption of crude steel may result in a 3.26 per cent increase
in China’s iron ore imports in the short run and a 4.33 per cent increase in
China’s iron ore imports in the long run. The difference in demand elastici-
ties of China’s iron ore imports between the short and long run suggests
that the impacts of domestic consumption of iron and steel products on
imports of iron ore are much larger in the long run. This is consistent with
the increasing trend of China’s demand for iron ore from the international
market as shown in Table 8.1.
Second, China’s imports of iron ore from the international market are
price- inelastic. Table 8.4 shows that the coefficient of the real price of iron
ore in the international market is positive, but statistically insignificant at
the 10 per cent level in the first- difference model, while that of the lagged
real price of iron ore in the international market is negative and statisti-
cally insignificant at the 10 per cent level in the error correction model.
These results may suggest that China’s iron ore imports have generally
been independent of the real price of iron ore in the international market
during the four decades up to 2007. The lack of price elasticity can also
be verified by the co- movement of China’s imports of iron ore from the
international market and the change in the real price of iron ore in the later
years of this period. A possible explanation is that the increase in China’s
demand for iron ore was so large that it also raised the domestic prices
of iron ore supply, reducing the price difference between supplies from
the domestic and international markets. Such an effect would weaken the
ability of China’s iron and steel enterprises to switch their sources of iron
ore inputs from the international market to the domestic one in response
to the surge of iron ore prices worldwide.2
Third, the domestic supply of iron ore is a substitute for importing iron
M3021 - SONG 978184844658 PRINT.indd 158M3021 - SONG 978184844658 PRINT.indd 158 23/11/2012 14:5123/11/2012 14:51
The iron ore import demand 159
ore from the international market, but the substitutability is seriously
restricted by the poor ferrous content in domestically supplied iron ore.
As shown in Table 8.4, the coefficient of domestic iron ore production
in the first- difference model is negative and statistically significant at the
5 per cent level while that in the error correction model is negative and
significant at the 1 per cent level. This implies that the domestic supply of
iron ore in China can play an important role in substituting for imports.
However, the substitution elasticity of domestic supply retrieved from the
error correction model in the short run is more than that in the long run
(−2.68 and −1.41, respectively, as estimated from Table 8.4). This implies
that a 1 per cent increase in domestic supply may substitute 2.68 per cent
of imports in the short run compared to only 1.41 per cent of imports in
the long run. This finding also suggests that the substitutability of domes-
tic supply of iron ore for imports is weaker in the long run. A possible
explanation is that there is a significant quality difference between domes-
tic and imported iron ore. The difference in quality makes China’s iron
and steel enterprises prefer to import iron ore in the long run, all other
things being equal. This interpretation can be supported by the evidence
from the negative and significant elasticities of China’s iron ore imports to
the ferrous contents of China’s crude iron ore in both the short and long
run (−3.11 per cent and −2.56 per cent, respectively, as estimated from
Table 8.4).3
Fourth, although exports of pig iron seem to have a positive impact
on China’s iron ore imports, exports of steel products do not. Table 8.4
shows that the coefficients of exports of both pig iron and steel products
in the first- difference model are insignificant, while only the coefficient of
exports of pig iron (one out of four coefficients) in the error correction
model is positive and statistically significant at the 5 per cent level. This
may imply that no significant positive relationship exists between exports
of iron and steel products and China’s iron ore imports from an empiri-
cal perspective.4 A policy implication is that restricting exports of iron
and steel products might not be an efficient way for China to reduce its
iron and steel enterprises’ dependence on imports of iron ore, particularly
when the efficiency effects of exports of these products by Chinese firms
and the structural linkage with the steel mills in China are considered (see
Chapter 9).
CONCLUSIONS
The dramatic increase in China’s imports of iron ore since the late 1990s
has exerted considerable pressure on world supplies of the ore, resulting
M3021 - SONG 978184844658 PRINT.indd 159M3021 - SONG 978184844658 PRINT.indd 159 23/11/2012 14:5123/11/2012 14:51
160 The Chinese steel industry’s transformation
in a rapid increase in prices on the international market. What are the
determinants behind such an increase in China’s demand for iron ore, and
how will this trend change in the future? These are questions which have
important implications for both users and suppliers of this key commod-
ity. To answer these questions, this chapter applies the time- series analysis
to examine China’s imports of iron ore and some of its determinants
from a demand perspective, using the industry- level data over the period
1960–2005. The results show that the rapid increase in China’s imports of
iron ore from the international market came mainly from China’s domes-
tic consumption of iron and steel products, and this trend has tended
to continue in the long run because China’s per capita consumption of
steel products is still relatively low and the country continues to be in the
middle phase of rapid industrialization. Moreover, since there are insuf-
ficient domestic supplies of iron ore, as well as significant quality differ-
ences between imported and domestic iron ore, the substitution between
the domestically supplied and imported iron ore is limited, particularly in
the long run since China’s imports of iron ore are largely price- inelastic.
This price inelasticity partly explains why iron ore prices on international
markets continued to rise strongly after 2005. It also suggests that a further
increase in the iron ore price on the international market is likely until the
large gap between supply and demand has been eased through either the
increase in supply as we observed has happened to the commodity market
in the second half of 2012, or the softening of demand. Finally, the empiri-
cal results do not reveal a significant positive link between China’s exports
of pig iron and steel products and its imports of iron ore. Therefore, it may
not be ideal in terms of efficiency for China to try to restrict the exports
of iron and steel products in order to ease the pressure of China’s iron ore
imports on the international market.
NOTES
1. Labson et al. (1995) showed that after processing China’s low- quality ore and imposing production taxes, the unit price of China’s iron ore inflated to approximately US$35 per wet tonne, which is much higher than the world trade price of US$25 per wet tonne.
2. The negotiations between the Chinese steel mills and the world suppliers of iron ore on long- term contracts since 2007 illustrate the point.
3. This finding seems to provide some assurance to the world suppliers of iron ore in making the long- term investment to meet the future demand for their products from China in the future.
4. This may be due to the fact that China had only begun to export iron and steel products since 2007 in response to the high prices of those products on international markets. It is also observed that the metal content of the exports from China have been on the rise, resulting from the shift in the export bundle from labour- intensive to capital- intensive products.

9. Restructuring China’s steel industry and the implications for energy use and the environment
Guoqing Dai and Ligang Song
INTRODUCTION
The steel industry is a relatively large energy consumer and polluter in China.
For example, in 2003, the shares of the key pollutants from the steel industry
in China’s total industrial emissions were as follows: waste water accounted
for 8.4 per cent, sulphur dioxide (SO2) 3.9 per cent, smoke 5.8 per cent, indus-
trial dust 15.3 per cent and chemical oxygen demand (COD) in industrial
water pollution 17 per cent.1 Energy consumption constitutes a significant
portion of the overall costs of steel production. For example, in 2000, energy
consumption accounted for 35 per cent of total production costs of the steel
industry. This compares selected energy- intensive industries as follows: 40
per cent for petrochemical, 50 per cent for aluminum, 40–50 per cent for
construction materials and 70–75 per cent for fertilizers. Although the share
of energy consumption in the total cost of production looks relatively low
compared with these other industries, the steel industry’s level of efficiency
in utilizing energy remains far below the global technological frontier. For
example, in 2000, the steel industry’s energy consumption per unit of crude
steel produced was about 40 per cent higher than the international level
based on the best technology applied in those developed countries.2
Given the continuing importance of the steel industry in the process
of industrialization and development in China, the country faces the
challenge of how to reform the industry through pursuing structural
adjustment that prioritizes energy savings and pollution reduction, while
ensuring that production levels continue to meet the increasing demand
for steel. Were the steel industry to succeed on these fronts then, it would
represent a major contribution to the realization of the goals set by the
central government in achieving energy efficiency and emissions reduction.
In this chapter, we discuss the progress being made in energy saving and
pollution reduction in the Chinese steel industry; identify those underly-

ing factors that drive improvements in energy and emissions efficiency;
and discuss how government could further implement those policies that
have proved to be successful in achieving the goals of improving energy
efficiency and emission reduction in the steel industry.
PROGRESS IN ENERGY SAVING AND POLLUTION REDUCTION IN THE STEEL INDUSTRY
Energy Saving and Conservation
The steel industry is a major energy user. In 2000, large steel mills con-
sumed 118 million tonnes of coal equivalent (Mtce), accounting for about
10 per cent of the national total energy consumption.3 As far as energy effi-
ciency is concerned, the steel industry faces the following major problems:
the proliferation of small firms with low degrees of industry concentration;
the use of backward technology and equipment, especially by those small
steel mills; and the concentration of production with low- value- added
products. Furthermore, the rapid growth of production capacity fuelled
by local governments, whose primary concerns are collection of taxation
and expansion of local employment, has not been beneficial from an envi-
ronmental perspective.
In dealing with these problems, the central government has since 2003
adopted various measures aimed at optimizing the industrial structure and
increasing industrial concentration, through the closure of a large number
of small operations; upgrading the technologies used in the existing firms;
and tightening up regulations regarding industrial pollution and emissions
control. Specific measures taken have included lifting the ratio of firms’
own capital to external finance to 40 per cent and then further to 60 per
cent for approving new projects; reducing tax rebates granted for exports
of certain steel products; directly controlling the scale of bank loans
flowing to the sector; and providing finance and technical support to firms
for emissions reduction.
The measures implemented by the government in addressing those
problems have produced some tangible outcomes. The industry achieved
substantial progress in energy saving, pollution reduction and water saving
in the few years after these policies were implemented. For example, the
unit energy consumption (energy intensity) dropped substantially. Taking
large and medium steel enterprises as a group, comprehensive energy con-
sumption per unit of output was reduced from 960 kgce/t of crude steel in
1999 to 645 kgce/t in 2006, a reduction of 33 per cent over eight years, as
illustrated in Figure 9.1.
M3021 - SONG 978184844658 PRINT.indd 163M3021 - SONG 978184844658 PRINT.indd 163 23/11/2012 14:5123/11/2012 14:51
164 The Chinese steel industry’s transformation
The trend of falling energy consumption per unit of steel output can be
compared with the increasing trend of the steel production over the same
period, as shown in Figure 9.2. The 33 per cent fall in energy intensity has
been accompanied by an increase of 3.4 times in the total steel output by
those large and medium firms over this period.
The reduction in energy intensity detailed above is impressive. However,
it should be noted that during this period the Chinese steel industry
achieved significant technological upgrading and extended the value chain
of production to a higher level, so that using a volume measure of steel is
likely to underestimate the extent of decline in energy use per unit of value
added. From 1999 to 2003, the gross output value (in constant prices) of the
Chinese steel industry increased by 213 per cent, while in the same period
the tonnage of crude steel output increased by only 79 per cent.4 Based on
this value term, the energy consumption of per unit of gross output value
in 2003 was roughly 50 per cent below that of 1999. This evidence suggests
that energy saving achieved by the steel industry has been quite compre-
hensive in coverage and substantial in extent. The overall trend is reflected
in all major processes of steel- making in China (Table 9.1).
Except for the basic oxygen furnace converter (BOF), which saw a sub-
stantial increase of 26 per cent in energy consumption per tonnage of steel
production between 2000 and 2005, all other processes witnessed falls in
energy intensities, especially EAF and rolling, which saw falls of 24 and 25
per cent over this period, respectively.

Reduction of Pollution
As a result of the policy measures, the pollution emissions of the indus-
try also dropped substantially. Over the period 2000–06, SO2, industrial
smoke and dust, and COD emissions were reduced by 52 per cent, 70 per
cent, 68 per cent and 77 per cent, respectively, as shown in Table 9.2.
A similar trend can be observed with respect to the solidified waste

generated by the steel industry (Table 9.3). The fall in solid waste was sub-
stantial, at 126 per cent reduction over the period under review.
Freshwater Saving
Freshwater is a scarce resource and is becoming increasingly so in China.
As a major water consumer, the steel industry has strengthened its efforts
in freshwater conservation in responding to the increasing scarcity of the
resource. For example, freshwater consumption in the steel industry fell
substantially from 25.24 t/t in 2000 to 6.56 t/t in 2006. At the same time,
the water reuse (recycling) rate greatly increased, from 88 per cent to 95
per cent over the same period (Figure 9.3).
Although enormous progress has been made since 2000, the industry
remains a major contributor to aggregate energy consumption and pollu-
tion emissions in China because of the nature and relative importance of
the industry in the Chinese economy in the second half of the first decade
of the twenty- first century. In 2006, the industry consumed around 15 per
cent of the country’s total industrial energy consumption. Its emissions of
waste water accounted for 14 per cent of the total industrial waste water

and its solid waste represented 16 per cent of the industrial total (Wang,
2007a). Therefore, further advancements in energy conservation and
pollution reduction remain an important task for the steel industry.
INCENTIVES FOR CHANGE IN ENERGY CONSERVATION AND POLLUTION REDUCTION
The main incentive for making progress in energy saving and pollution
reduction is that all Chinese steel companies, including both large and
small firms, are facing intense competitive pressure. There are over 300
integrated steel companies which produce both hot metal and final steel
products in China. Among them, 66 companies produced over 1 million
tonnes of crude steel in 2007. The market share of the top five largest steel
companies of China in 2007 was as follows: Baosteel Group (29 million
tonnes, world ranking five), accounting for 5.8 per cent of total steel
production; Anben Group (Anshan and Benxi, 24 million tonnes, world
ranking seven), accounting for 4.8 per cent of the total; Shagang Group
(23 million tonnes, world ranking eight), accounting for 4.7 per cent of the
total output; Tangsteel Group (23 million tonnes, world ranking nine),
accounting for 4.7 per cent; and WISCO (Wuhan steel, 20 million tonnes,
world ranking 11), accounting for 4.1 per cent of total steel production.

168 The Chinese steel industry’s transformation
The top five steel companies collectively control just under one quarter
of the market, which is far below the levels of industrial concentration
seen in the steel industries of major producing markets such as Europe,
North America, Japan and Korea. In such a fiercely competitive market,
steel- makers need to reduce their production costs by all possible means,
and reducing energy consumption is a large part of this effort. With the
cost of energy progressively moving towards a fully market- based system,
the imperative to economize on energy inputs in the industry will remain
in place.
A second reason for the increase in environmental efficiency is related
to the ongoing reform of SOEs and the associated changes in microeco-
nomic circumstances. In the past, most large and medium steel companies
were SOEs, and therefore developments impacting on this segment of the
economy were also highly relevant for steel firms. The administration of
most large and medium steel companies has been transferred from the
central government to provincial governments and also to more local
governments under whose jurisdictions those firms are physically located.
In 2007 only four steel companies, Baosteel, Anshan Steel, WISCO and
Panzhihua Steel, were under the administration of SASAC (State- owned
Assets Supervision and Administration Commission of the State Council).
One of the Chinese government’s policy objectives with respect to its
industry restructuring has been to encourage SOEs, including steel com-
panies, to undergo reform in ownership structure and ‘go public’ (that
is, become listed on the stock market) whenever and wherever possible.
In 2006 there were about 30 steel companies listed on the Shanghai and
Shenzhen stock exchanges. Some local governments sold off part or all of
their steel equity holdings during the process of privatization which had
been ongoing on a large scale in China since the early 1990s (Garnaut et
al., 2006). This dramatic change in the ownership structure in the industry
plays an important part in impacting on corporate attitudes towards effi-
ciency and productivity.
Another important contributor to changes in the energy use of the
steel firms was generated by the emergence and growth of private steel
companies. The market share of private steel companies was traditionally
small because the steel industry is so capital- intensive that most private
companies, usually small in scale, were not able to raise sufficient funds
to participate in this kind of production. However, during the ten years to
2007, the production from private steel companies has grown extremely
quickly. The output of steel produced by private steel companies reached
more than 40 per cent of the total output in 2007. The largest private steel
company, Shagang Group, was the third- largest producer of crude steel
(23 million tonnes) in China in 2007. Another private company, Fosun
M3021 - SONG 978184844658 PRINT.indd 168M3021 - SONG 978184844658 PRINT.indd 168 23/11/2012 14:5123/11/2012 14:51

International (listed in Hong Kong under the code 0656, HK), controlled
about 20 million tonnes of steel production capacity by its own investment
and through acquiring majority stakes in existing steel companies. CITIC
Pacific (0267, HK) was the leading specialized (alloy) steel- maker in
China. The efficiency drive of the entire steel industry has been accelerated
by the dynamic participation of private companies such as these.
As for the large SOEs in the industry, the various levels of government to
whom they belong are not involved directly in the daily operations of firms’
management. Rather the focus is on the issues of large- scale investment
and the appointment of senior executives. These firms have enough opera-
tional autonomy and the profit incentives to implement energy- saving and
pollution- reduction measures as part of the industry’s restructuring.
A further incentive to achieve energy savings is that prices for coal and
freshwater rose strongly over the decade to 2007 as part of the govern-
ment’s efforts to rectify the distortions in factor markets. After the SOE
reforms, the motive for profits has become central to the concerns of man-
agement. The continual increases of the prices of some of the inputs such as
iron ore have forced the steel companies to economize on energy and water
consumption, although the degree to which this can be achieved is limited
by the pace of technical progress underway in the industry. For example,
the price of coking coal delivered to Shoudu (Capital) Steel Corporation
in 2007 was 122 per cent higher than the level in 2001. During this period,
the coking rate (kg per tonne crude steel) was reduced by 13 per cent.
Technically speaking, it is not easy to achieve such reductions in the coking
rate, but the price signal is a powerful driver for firms to do so, and enter-
prises did respond accordingly. The reduction of freshwater consumption
per tonne of steel production can be explained along similar lines.
Over time, technological upgrading and improvement in economies of
scale have both contributed positively to energy conservation. In meeting
the challenges of restructuring the industry, further measures have been
taken to promote energy saving and pollution reduction. First, efforts have
been made to reduce the iron- to- steel ratio and increase the continuous-
casting ratio and the rolling yield. In an integrated steel mill, iron- making
takes over two- thirds of total energy consumption. Therefore, reducing
the amount of hot metal used in steel- making is a significant avenue for
achieving energy savings. As a result, the iron- to- steel ratio decreased sig-
nificantly over the period 2000–06, as shown in Table 9.4.
Steel casting techniques have changed progressively from a traditional
reliance on mould casting to a predominance of continuous casting pro-
cesses which have reduced energy consumption dramatically and increased
the rolling yield. The industry has made great progress on this front, as
detailed elsewhere in this book and illustrated by Figure 9.4.
M3021 - SONG 978184844658 PRINT.indd 169M3021 - SONG 978184844658 PRINT.indd 169 23/11/2012 14:5123/11/2012 14:51
170 The Chinese steel industry’s transformation
Economies of scale are positively associated with firms’ energy savings
(Table 9.5). On all the measures reported in Table 9.5 including energy
consumption, coking ratio, water use and emissions, large operations are
all superior to smaller ones. Considering the fact that many small steel
mills still operate in China, one can easily conclude that to increase the
scale of operation (equipment) by increasing the industry concentration
is an effective way of reaching the goals of energy savings and emission
reduction in the steel industry.
During the ten- year period to 2006, Chinese steel enterprises upgraded
their equipment to a larger scale. Consequently, the number of large- scale
operations in the industry increased dramatically over the period 1995–
2006, as shown in Table 9.6. Table 9.6 shows that in 2006, there were 50
blast furnaces (BF) (of a total of 275) with production capacities of 2000

172 The Chinese steel industry’s transformation
for the entire industry (Wang, C. and Chi, 2007). However, the industry
has remained highly fragmented by international standards. Hence, elimi-
nating small and medium- sized production is a priority if further energy
savings are to be achieved through increasing economies of scale and
upgrading the technologies used in the industry.
The industry is making progress in promoting secondary energy uti-
lization and other energy- saving technology. For example, the reuse of
energy, particularly secondary energy (residual heat and residual energy)
is a main energy- saving measure of many steel- makers. In recent years,
TRT, CDQ, BF/converter gas recovery (defined below) and its reuse have
been widely introduced by large and medium steel enterprises in China.
● Top gas pressure recovery turbine (TRT) – The total number of blast
furnaces BFs in 2007 in China was around 1200, of which 120 had
capacity of more than 1000 m3. There were about 210 sets of TRT in
operation, of which the coverage for the BFs larger than 1000m3 was
over 90 per cent. The total power generated by TRT was 2.1 billion
kilowatt hours (kW h) in 2007 (Wang, 2007c).
● Coke dry quenching (CDQ) – CDQ technology can reduce compre-
hensive energy consumption by about 15 kgce/tonne. By the end of
2006, China had set up 44 sets of CDQ with a capacity of 48 million
tonnes per year. At that time, coke ovens with the CDQ system were
used in only a small proportion of operations (Wang, 2007b). By the
end of 2008, China had nearly 80 sets of CDQ devices, with produc-
tion capacity of 70 million tonnes of steel per year.
● BF/converter gas recovery equipment – By the end of 2006, 77 per
cent of the key steel enterprises had installed BF gas recovery equip-
ment, and a total of 261 billion m3 of gas was recovered from using
that system that year; 64 per cent of key large steel enterprises had
installed converter gas recovery equipment, and 10 billion m3 of
gas was recovered; 68 per cent of key steel enterprises had installed
converter residual heat steam recovery equipment producing similar
results in terms of energy savings.
● BF/converter dry dust removal system – BF and converter dry dust
removal systems can not only save energy but also reduce dust emis-
sions. There are many Chinese steel- makers that have introduced
these two systems.
According to a report by CISA, in the period 1990–99, process optimiza-
tion, energy management enhancement, energy- saving equipment and/or
technology, and raw materials improvement contributed to energy saving
by 41, 25, 19 and 15 per cent, respectively.

Restructuring China’s steel industry 173
The Chinese government complements the efforts of individual firms
by implementing policies that encourage energy saving and environmental
protection. On 8 July 2005, the NDRC issued Decree 35, ‘Steel Industry
Development Policy’. This document clearly indicates that (the steel
companies) ‘should save energy and decrease the energy consumption
level, improve the standard of environment protection and make full,
multiple and reasonable use of resources according the principle of sus-
tainable development and recycling economy’. They should ‘improve the
standard of making full, multiple and reasonable use of waste gas, liquid,
residue, etc. as large as possible, work hard to achieve “zero discharge”,
transform the original steel mills into recycling ones’. The NDRC also
promulgated the concrete average consumption standards of energy and
freshwater for the whole steel industry. It demanded the phasing out of
obsolete equipment and listed the standards that enterprises need to meet
in installing new equipment.
Separately, the State Environmental Protection Administration (SEPA)
issued ‘Cleaner Production Standard – Iron and Steel Industry’ (HJ/
T189- 2006) in 2006 which included the following three measures. First,
the export of energy- intensive or high- pollution products was discouraged
by cancelling export tax rebates and even imposing an additional export
tax for some steel products. Second, the State Council, NDRC, NBS and
SEPA, now the Ministry of Environmental Protection (MEP), jointly
issued a statistical index system of energy consumption per unit of GDP in
November 2007, to force local governments and enterprises to incorporate
energy consumption into the overall evaluation of economic and social
development and annual performance evaluations. The amended Act of
Energy Conservation came into effect on 1 April 2009. Third, to reduce
the pollution in Beijing, the central government had decided several years
previously to have Shoudu (Capital) Steel Corporation (with 8 million
tonnes of crude steel production) stop production in metropolitan Beijing
and relocate to Caofeidian, a coastal site near Tangshan city in Hebei
province. Some other large steel companies also plan to move out of big
cities and are choosing less populous sites for rebuilding their factories.
Furthermore, there is a huge gap between China’s most advanced steel
enterprises and the industry laggards regarding their performance in
energy saving and environmental protection. Generally speaking, large
and medium enterprises have invested more and achieved relatively more
significant outcomes with respect to energy saving and environmental pro-
tection, while small firms have made much slower progress. According to
one study by CISA, the coking rate of the large enterprises was only 58–80
per cent of that for the least- efficient small firms, as shown in Table 9.7.
Finally, mergers and acquisitions (M&As) within the steel industry are
M3021 - SONG 978184844658 PRINT.indd 173M3021 - SONG 978184844658 PRINT.indd 173 23/11/2012 14:5123/11/2012 14:51
174 The Chinese steel industry’s transformation
promoting energy saving and pollution reduction. Baosteel and Shoudu
(Capital) Steel Corporation acquired Bayi Steel and Shuicheng Steel
in early 2007 and 2006, respectively. From a technical perspective, the
two acquired companies had made great progress in energy saving after
being merged with the large firms (Tables 9.8 and 9.9). In both cases, the
records for energy (water) saving were remarkable. Within two years,
energy consumption was reduced by 21 per cent for Shuicheng Steel and
11 per cent for Bayi Steel and their water consumption was reduced by 29
and 39 per cent, respectively. The policy implication is clear that China
should accelerate the pace of consolidation in the steel industry through
M&As or other means of cooperation such as taking over through share-
holdings. This would not only change the industry’s rates of energy effi-
ciency, water use and pollution, but also improve the industry’s overall
performance through increased industry concentration, expanded econo-
mies of scale, application of more advanced technologies and efficient
management. Of course, in order to achieve this goal China needs to
overcome the rampant local protectism which has prevented M&As from
happening in the past.

Restructuring China’s steel industry 175
CONCLUSIONS
The Chinese steel industry has made significant progress in achieving
energy conservation and environmental protection. However, based on
international benchmarks there is still considerable room for improve-
ment. To make further progress, the Chinese steel industry should endeav-
our to enhance technological advancement, seek economies of scale and
further improve management through deepening corporate reform. The
industry and government should allow more M&As to take place in order
to increase industrial concentration. Much needs to be done to continue
building on the achievements in the industry made thus far. The steel
industry has a major part to play in achieving China’s ambitious national
goals regarding energy saving and environmental protection.
