A successful e-government system lies not only in technology, but also in the user＇ s acceptance of the system. On the basis of theoretical analysis, we construct a model of acceptance of the government portal website services and test the model by empirical survey. The results show that subjective norm and network externality play significant roles in information processing and information exchange services respectively, that self efficiency plays significant roles in information processing and information exchange services, that compati- bility has directly positive effect on basic information and information exchange services, that convenience has great influence on citizens＇ adoption intention at all three service levels and that the two antecedents of perceived trust are trust in internet and trust in government. Finally, based on the conclusion of this research, we come up with some suggestions to help to develop e-government system services
