Towards a Model of Macao’s E-Government Portal Adoption

Electronic government is an information system (IS) that uses information and communication technology to improve public administration efficiency and policy effectiveness, to increase the convenience, performance and accessibility of government services to internal and external users. This research tests an integrated model of e-Government satisfaction that incorporates constructs from the technology acceptance model (TAM) and end-user satisfaction (EUS). The model explains a large proportion of the variance in citizen’s intention-to-reuse Macao’s e-Government portal. Empirical results support the hypothesis that satisfaction with the e-Government portal partially mediates the relationship between success factors and intention-to-reuse the portal.Information quality, system quality and social influence (but not perceived effectiveness) were confirmed as determinants of the adoption of, and satisfaction with Macao’s e-Government portal.
