• We focus on two main characteristics of Chinese growth, i.e., an authoritarian political institution and high income inequality.
• For each feature, we show firstly the facts, and then a theoretic model.

– The saving rate increases in the income.
– The rich saves more than the poor proportionally.
– Hence, redistribution from the poor to the rich will increase the aggregate investment

• What is this kind of output?
– Human Capital
– The poor guy can achieve more human capital than the rich when both of them get 1 Dollar additionally.
– If there is a perfect capital market
– The poor can borrow from the rich

– However, the capital market in reality is imperfect.
– Hence, redistribution from the rich to the poor is good for the economic growth.

5. Unbalanced economy in China: capital market
• Literature: Growing like China (Song 2009)
• Some stylized facts:
– High saving rates and huge investment
– What should we expect with this fact?
![Page 57: Unbalanced growth in China --- understanding Chinese Success in a framework of political economy](https://reader036.vdocuments.mx/reader036/viewer/2022062301/56814afb550346895db80dbb/html5/thumbnails/57.jpg)

– high return rate of capital
– What should we expect with this fact?
– huge foreign reserves

• A theory with two sectors: SOE & DPE
– SOE is less efficient
DPE is more efficient

• A theory with two sectors: SOE & DPE
– However, Chinese banks are SOE, too.
– Hence, it is much easier for SOE to get loans from financial markets.
– DPEs have to save for themselves.

23/4/21 62
• A theory with two sectors: SOE & DPE
– Starting from huge investment
– Although both sectors have a decreasing tendency of the return rate, the share of DPE increases.
– It leads to a moderate decreasing return to capital in China.
