Electronic Bidding System (EBS) is one of the most important operational solutions of public administration, as well as the establishment of the conditions necessary for taking advantage of electronic administration. But few papers discussed the users´ aesthesis in using Electronic Bidding System for the feedback control. Thus the main purpose of this paper is to investigate the current status and the factors of the users intentions and behaviors in using Electronic Bidding System. The judgment framework is Structural Equation Modeling (SEM) based on the Unified Theory of Acceptance and Use of Technology Model (UTAUT) to research the influence of the four factors, Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions on the intentions and behaviors. A questionnaire survey is conducted to collect 192 valid samples for quantitative analysis. The sample number in Tainan Taiwan is 102 and the others are from Nanping Fujian. The results are shown as following. (1). Performance Expectancy and Social Influence have a significantly impact on the users´ intentions and behaviors in using Electronic Bidding System, but not in Effort Expectancy. (2). Facilitating Conditions have a significantly impact on the users´ behaviors in using Electronic Bidding System, but in use Intention. (3). The difference between samples from Tainan Taiwan and Nanping Fujian are significant in 5 of 9 factors.
