Its purpose is to improve administrative efficiency, reduce waste of resources and enhance their competitiveness. Therefore, administrative persons can quickly and easily utilize this system to complete the purchase, dismiss unnecessary inquiry and tender procedures. Hence, we try to investigate the adoption and influencing factors of using this IS for elementary school procurement staff in Chiayi County. That may be executed by the county government. 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 ease of use (PE) and perceived usefulness (PU) as well as the external construct of computer self-efficacy (CSE) reflecting general acceptance of the system. In addition, we consider the perception of credibility (PC) to reflect the concern of system security, forming the other mediation construct. To explore the various situations of behavioral intention, we have questionnaire design and collection of survey data to do statistical analysis, and recover 92 valid questionnaires to estimate the path coefficient of this model. The results show that PU as well as PC plays the most important factors to directly affect BI, and indirectly effected by PE which is the secondary. In total, PC is more important. Moreover, CSE has the direct impact on PE as well as PC and an indirect influence on BI. Therefore, these results reveal that the priority issue for behavioral intention is to design safety and secured user interface and system process. Related problems are also discussed.
