E-government offers unprecedented opportunities for innovating andtransforming the way public service is delivered. To ensure successful e-govern-ment, it is necessary to understand how citizens accept new technology andreceive services from e-government. In the context of e-government acceptance,this paper introduces and tests three well-known theoretical models-SERVQUAL, the American Customer Service Index, and the technology accep-tance model-adapted from the service quality and technology acceptance litera-ture. In addition, a new process model of e-government acceptance is synthe-sized and proposed. Using structural equation modeling methods, empirical fittests are carried out to evaluate the potential and explanation power of four theo-retical e-government acceptance models. The results show that each model has ahigh potential for explaining e-government acceptance processes by citizen. Fit-ted theoretical models imply that the key ingredients for successful e-govern-ment are service quality, ease of use, and usefulness, which strongly suggeststhat for successful e-government, citizen focused e-government is crucial. E-government is a moving target, and the results hint at strategic directions for e-government development.
