Asia Pacific Journal of Information Systems Vol. 21, No. 1, March 2011 1) Determinants of E-Government Assimilation in Indonesia: An Empirical Investigation Using a TOE Framework Boni Pudjianto*, Hangjung Zo**, Andrew P. Ciganek***, Jae Jeung Rho**** E-government needs to be successfully implemented and assimilated into organizations to take advantage of its potential values and benefits for organizations. This study examines factors for e-government assimilation in Indonesia and employs the TOE (Technology-Organization-Environment) framework to develop a theoretical model to explain e-government assimilation. It also investigates how organizational type (central vs. local) plays a role in the assimilation of e-government. One hundred eighteen respondents from the central and local governments in Indonesia participated in the survey and an in-depth analysis based on partial least squares (PLS) was carried out. The results show that ICT infrastructure has the strongest significant relationship with e-government assimilation. Top management support, regulatory environment, ICT expertise, and com- petitive environment are also significant factors to explain e-government assimilation in Indonesia. Central and local governments significantly differ in terms of e-government assimilation, so organizational type can be a moderator in the process of e-government assimilation. These findings present the efficacy of the pro- posed model for analyzing e-government assimilation and contribute additional insights for academia as well as practitioners and policy makers.
