AN EMPIRICAL STUDY ON THE DETERMINANTS OF USER ACCEPTANCE OF e-GOVERNMENT IN PUBLIC SECTOR

摘要

The purpose of this paper is to examine the determinants of user acceptance of e-Government in public sector by using the technology acceptance model (TAM) as a based theoretical model. The model of e-Government acceptance in public sector integrates constructs from TAM, the extended TAM (TAM2), the diffusion of innovation (DOI), and trust literature. To empirically test the model, the data were collected from 112 public officers in 10 ministries in Cambodia. The finding shows that image and output quality are significant influential determinants toward perceived usefulness. Perceived usefulness, relative advantage, and trust are significant determinants toward the acceptance of e-Government usage in public sector.
