Then we talk about the main topic of this research, “Infrastructure as a Service”. We mention its background information, its benefits, and its drawbacks. After carefully examining the literatures, we form the research framework based on TOE framework, which has three major dimensions: Technological, Organizational, and Environmental. The variables in our research framework are “Perceived Efficiency Improvement” and “Perceived Cost Reduction” in Technological dimension, “Satisfaction with Existing IT Infrastructure” and “IT Knowledge” in Organizational Dimension, and “Agency Trust” and “Vendors'' Promotion” in Environmental Dimension. The dependent variable of this research is “Intention to Adopt.” We use questionnaires to investigate. The subjects are the IT managers who come from the government agency in Taiwan. The research results show that “Perceived Efficiency Improvement,” “IT Knowledge,” and “Vendors'' Promotion” have significant impact on the “Intention to Adopt” IaaS. According to the research results, we suggest that the IaaS service providers should put a high premium on the education of their customers, put more time and effort into promotion activities to improve customers’ willingness to adopt IaaS. Moreover, it is easier to begin with one of the government agencies that have a perceived higher IT knowledge capability. For future researchers, they can incorporate other enabling factors or hindering factors into their research framework and incorporate more government-specific characteristics into their framework to fit in more with the research context. They also can conduct research on experienced users of IaaS since there may be some inexperienced users being our respondents.505329 bytesapplication/pdfen-US雲端運算基礎架構即服務政府雲資訊科技採用Cloud ComputingInfrastructure as a ServiceGovernment CloudInformation Technology Adoptionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/251461/1/ntu-100-R98725031-1.pdf
