During the last decade, governments around the world have realised the potential benefits of e-government and have started planning and allocating resources to make it possible. Despite the significant increase in such initiatives, there is evidence to suggest that stakeholder adoption of online government services has not yet met expectations. Thus, it is important to understand the factors that might influence people's intentions to adopt and use government services provided over the Internet. A literature review reveals several gaps, the most important being the limited research in the area of e-government adoption and acceptance in general and in developing countries in particular. This study, therefore, was undertaken with the primary aim of identifying, examining and providing an understanding of the intention and the factors that could affect the intention of firms to adopt and use e-government services. The Technology Acceptance Model (TAM) developed by Davis (1989) is used as a theoretical framework to build a conceptual model, while two additional constructs are utilized to measure the uncertainty arising from using government services over the Internet: perceived risk and trust. Finally, the modified TAM model and twenty-four hypotheses are proposed to explain and test the intention of businesses to adopt and use electronic government services. Data was collected by a mail survey; a questionnaire was sent to 500 companies in Jordan, having been validated using expert opinion and a pilot survey of 16 managers. Responses are analysed in line with the research questions. The findings are that four main factors affect firms' intention to engage in egovernment services: perceived ease of use, perceived usefulness, perceived risk and trust in electronic channels. Furthermore, four moderators firm size, Internet experience, manager's gender and age moderate the influence of adoption factors on intention. The modified research model explains more than half of the variance in firms' intention to adopt and use e-government services.
