E-government Research Domain
Studies have focused on the e-government (EG) research domain in general (Heeks & Bailur, 2007; Yildiz, 2007) or specific topics: Provided region-specific analyses (Khan, et al., 2011)E-participation (Sæbo, et al., 2008) E-government models (Andersen & Henriksen, 2006)Digital divide (Helbig, et al., 2009)E-government design science (Fedorowicz & Dias, 2010
), Information sharing in public sector (
Yang & Maxwell, 2011)Aging populations (Niehaves, 2011), and Theoretical constructs used in EG research domain (
Khan, et al., in press)
E-government Research Domain
Focused on:Methods and problems related to
the areaPolicy lessonsEG research communities, or Socio-cultural issues related to the
EG research domain
ProblemCrucial, but they shed no light on the
hidden structures and properties of EG domain:Key players and their connectivity patterns; Characteristics of scientific collaboration
networks (e.g., degree centrality, density, and clusters); and
Collaboration at the institutional level have not been analyzed and synthesized adequately
Why? & What?
They use systematic literature review (SLR) method (Kitchenham, 2004).Helpful in understanding general factsMay lead to Type 1 and Type 2 errorsLimited in revealing certain hidden structures
and network properties Need for a Social Network Approach (
Wasserman & Faust, 1994) and TH indicators (Leydesdorff, 2003).
Research Questions (RQ)
RQ1: What is pattern and network structure of collaboration at the institutional, country, and regional levels in the network of EG knowledge production?
RQ2: Based on network characteristics, who are the key players (i.e., institutions, countries, and regions) contributing to the network of EG knowledge production?
RQ3: How strong/weak are the university-industry-government relationships in the network of EG knowledge production?
Data
Papers (e.g., journal articles and conference proceedings) published(2000-2011) in SCI, SCI-E, SSCI, and A&HCI journals from the Web of Science database.
Had a least one keyword: e-government, electronic government, paperless
government, online government, web-based government, e-governance, electronic governance, and online governance.
Papers appeared in 310 outlets

To analyze UIG relationships, we divided authors' affiliated institutions into three categories: “university” (U), “industry” (I), and “government” (G). For example, a paper authored by a single
university-based researcher or that coauthored by university-based researchers was classified as “U,” and a paper authored by at least one university-based researcher and one industry-based researcher was classified as “UI.”

2003).
Method continue…TH model
T-values
T(ig) = Hi + Hg –Hig. (1)
T(uig) = Hu + Hi + Hg –Hui –Hig –Hug + Huig. (2)
We used co-authorship data to measure T-values:

For example: Negative three dimensional T-values (i.e., uig) indicates a decrease in uncertainty and Indicate synergy in the UIG relations

Discussion
Country-Level networksDeveloped countries lead with a well establish
collaboration networkDeveloping country participation is solo & marginal
• Except some emerging economies Singapore, China
Anomalies in the publication vs. implementation abilitye.g. Korea world leader in e-government (UN, 2010),
but publish limited research (in English)China good in publication, but bad in implementation
Discussion
We suggest use of a Hybrid index: an index that consider implementation vs. publication capabilities of nationsA hybrid index can be constructed, which
may allow for a better comparison between the actual ability to implement technologies (or systems) and the theoretical ability (e.g. to publish papers) in various fields.
Discussion
Region-Level NetworksNetwork not balance in terms of strength &
pattern of tiesDeveloping countries preferred research ties
with developed countries to those with other developing countries.• Such ties may be useful for knowledge transfer
from developed countries to developing countries, but the lack of vertical and horizontal ties among developing countries is alarming. Limit the transfer of knowledge and experience between
developing countries during the implementation of EG systems.
Discussion
Institution-Level AnalysisU.S. institutions dominated EG researchHowever, there were international, cross-
regional, and institution-wide clusters of institutions, and most clusters were tightly integrated.
Each cluster had a key institution In some cases the key institutions belings to
different region!Not balanced in terms of UIG relations
Discussion
TH Indicators: UIG RelationshipsLack of strong bilateral and trilateral UIG
relationships in the EG research domainGood UIG relationships are crucial for any
knowledge-based innovation systems (Etzkowitz & Leydesdorff, 2000; Leydesdorff, 2003)
However, the UG relationship was stronger than the UI, IG, and UIG relationships.
Limitations
Generalization maybe in issue.Only analyzed ISI based publicationsWe did not considered non-indexed outlets (mini tracks,
conferences, journals, case studies, etc). Invisible e-government research e.g. applied research,
confidential or politically sensitivity studies not published in scientific outlets is excluded.
Some keywords used in parts of world were misseddigital government, transformative or t-
government, and informatization
