A Cross - Country Study on E - Government Interoperability Capability and E-Government Services

Nowadays, e-Government is increasingly playing an important role in the development strategy of countries around the world, paying special attention to the field of E-Services.Countries' governments have invested a lot of money in developing e-Government, but the results have not been as effective as expected.The online service index (OSI) has differences between countries and territories.The main reason for this situation is that when developing e-Government development strategies, countries do not consider both technical factors and political, social and environmental factors.Limitations of literature are studies that are mostly focused on a specific country or countries but focus on only a few specific factors.The question is how and how the E-Government Interoperability capability can affect E-Service provision in different countries and territories around the world.Therefore, this paper will use Technology -Organization -Environment (TOE) method combined with secondary data source from the World Economic Forum's International Data Technology Report (WEF).After data analysis and evaluation, the final result reflects the growth of e-Government interoperability maturity (ICT Infrastructure, Human Capital, Electronic Participation) and ICT Legal environment have affect to e-service provision.Based on different characteristics and different compatibility, each country has a different online service development model.Finally, the contribution analysis, limitation and several recommendations are given, in order to help policy makers, Government Leaders and citizens understand the importance of the E-Government Interoperability capability, e-Services and thereby outline the specific roadmap and development strategy suitable for each country.
