Summary	Po-Ting Liu, 2006.06 Department of Transportation Technology and Management National Chiao Tung University 　　It’s very common that organizations introduce new information technology (IT) to enhance their benefit. In order to enhance the efficiency of the new IT, studies about the users’acceptance and behavior are very important. There are numerous theories and models have been developed in the technology acceptance behavior study field. But the variables and the causal relationships among the numerous theory models are different. We select Technology Acceptance Model (TAM), Combined TAM and Theory of Planned Behavior (C-TAM-TPB) and Unified Theory of Acceptance and Use of Technology (UTAUT) which are suitable for this study by the literature review and the characteristic of the parking fee collecting industry. 　　In order to test the adaptability of the construct models, we use the SEM to analysis the collecting data by confirmatory factor analysis, path analysis, models compare analyze and moderators analyze. The objects of study are the Taipei Parking Management Office’s parking fee collectors. According to the difference of using experience, we handed out the questionnaires in July to November 2005. Granted 604 questionnaires altogether in this research, the effective questionnaires were 666. 　　According to the results of this study, expected performance, expected effort, social influence, facility condition and attitude toward behavior are very important constructs to the using behavior and behavior intention of technology acceptance. 　　In the models compare analysis, TAM, C-TAM-TPB and UTAUT show certain degree of adaptability in the parking fee collecting industry, but TAM and UTAUT perform better. In the moderators analysis, the using experience, users’gender and ages are significant moderators of these models. 　　In the management implication, in order to raise the using behavior intention and the benefit of the new system, the managemers should enhance the education and training quality and quantity. Making the users know how much benefit the new IT could bring in, and increase the practice chance before the adoption. Second, managemers should increase gentle or individual using explanations to decrease the negative effect of attitude toward behavior and social influence. Furthermore, the effects of the important constructs to behavior intention of the elder and male users are weaker. So, in order to enhance the integrated organization benefit, the managemers should design education and training programs or using explanations to these two type users.

　　It’s very common that organizations introduce new information technology (IT) to enhance their benefit. In order to enhance the efficiency of the new IT, studies about the users’acceptance and behavior are very important. There are numerous theories and models have been developed in the technology acceptance behavior study field. But the variables and the causal relationships among the numerous theory models are different. We select Technology Acceptance Model (TAM), Combined TAM and Theory of Planned Behavior (C-TAM-TPB) and Unified Theory of Acceptance and Use of Technology (UTAUT) which are suitable for this study by the literature review and the characteristic of the parking fee collecting industry.
　　In order to test the adaptability of the construct models, we use the SEM to analysis the collecting data by confirmatory factor analysis, path analysis, models compare analyze and moderators analyze. The objects of study are the Taipei Parking Management Office’s parking fee collectors. According to the difference of using experience, we handed out the questionnaires in July to November 2005. Granted 604 questionnaires altogether in this research, the effective questionnaires were 666.
　　According to the results of this study, expected performance, expected effort, social influence, facility condition and attitude toward behavior are very important constructs to the using behavior and behavior intention of technology acceptance.
　　In the models compare analysis, TAM, C-TAM-TPB and UTAUT show certain degree of adaptability in the parking fee collecting industry, but TAM and UTAUT perform better. In the moderators analysis, the using experience, users’gender and ages are significant moderators of these models.
　　In the management implication, in order to raise the using behavior intention and the benefit of the new system, the managemers should enhance the education and training quality and quantity. Making the users know how much benefit the new IT could bring in, and increase the practice chance before the adoption. Second, managemers should increase gentle or individual using explanations to decrease the negative effect of attitude toward behavior and social influence.

So, in order to enhance the integrated organization benefit, the managemers should design education and training programs or using explanations to these two type users.
