To implement electronic-government (e-government) services successfully, it is important to know the factors that influence their acceptance. In this study, we investigated the influence of trust and compatibility in the context of usage intention of e-government services in Macao. In Macao, government services are easily accessible via government departments and offices. Switching to e-government services would require users’ trust and having the services fit into the users’ way of life. The results of our analyses found that trust and compatibility are positively related to usage intention and that the independent variables accounted for 63 percent of the variance in usage intention. We discussed the implications of the research findings.
