碩士 === 國防大學 === 資訊管理學系 === 105 === With the increasing trend of internet application, the Research, Development and Evaluation Commission (RDEC) of the Executive Yuan has been planning to set up a government e-procurement system since 1996, Common Supply Contracts Information System (CSCIS) is one part of it. The purpose is to improve administrative executive efficiency, reduce waste of resources and enhance competitiveness. Make the government procurement staff can get rid of unnecessary inquiry and tender procedures, complete the procurement action through this system. My study focuses on investigating the adoption and influencing factors from the Air Force procurement staff users of the CSCIS. To explore the possible influencing factors, we apply TAM to the modeling. It consists of the behavioral intention (BI) as the result construct, coupled with the mediation construct of the perceived usefulness (PU) and perceived ease of use (PE) as well as the external construct of computer self-efficacy (CSE) and convenience to reflect general acceptance of the system. In addition, we take the convenience as another mediating variable to my study to research that whether it has the effect of enhancing perceived usefulness and perceived ease of use. I have done statistical analysis through designed questionnaire and collection of survey data, which recover 174 valid questionnaires. The results of the study show that perceived ease of use is the most, perceived usefulness (PU) is the second and convenience is the third. In addition, users who have better computer skills showed a short adaptation period and a high degree of proficiency and easy to operate the CSCIS. Those also recognize that the CSCIS can help users in the procurement business. Meanwhile, convenience also significantly influenced users attitudes, indicating that users perceived the use of the CSCIS to accomplish procurement tasks that could save time and effort perception, but did not perceive that convenience could enhance operate the CSCIS easily for the users and has a useful understanding of the procurement business.
