A Conceptual Model of e-Government Acceptance in Public Sector

The purpose of this paper is to develop a conceptual model for e-Government acceptance in public sector which is one of the least studied aspects of e-Government. The proposed model uses theories from technology acceptance and success and the diffusion of ICT-related innovations. It integrates constructs from the Technology Acceptance Model (TAM), the theoretical extension of the TAM (TAM2), the Diffusion of Innovation (DOI), the Updated DeLone and McLean (D&M) IS Success Model, trust and risk literature, to explain and analyze the factors influencing public officers’ acceptance of e-Government services. The conceptual model, as well as providing a foundation for further empirical testing, will have some practical issue to government decision makers as it synthesizes much of the current research regarding to e-Government acceptance into a single model. It will have important policy and strategy implications for helping government in increasing public officers’ acceptance of e-Government usage.
