Private sector is important for a country as it contributes to the economy and GDP of a country to a greater extent. E-government is the use of latest technologies in the services provided by the government and other information management systems. Research and development is the process applied before introducing a new product or starting a new business. This study analyzes the influence of e-government adoption and R&D process on private sector contribution of GDP in ASEAN countries. Two control variables i.e. literacy rate and per capita income have also been used. The past studies have been discussed in literature review section. For analysis purpose, data about the concerned variables has been collected from ASEAN countries for 27 years. After application of several tests and methods i.e. IPS unit root test, Pedroni cointegration test and FMOLS coefficient estimation test, the two major hypotheses of this study are accepted along with the impact of a control variable, literacy rate. However, the impact of other control variable i.e. per capita income is rejected. This study has various implications in theoretical, practical and policy making context in order to increase the performance and GDP contribution by private sector.
