During the past 30 years, the research regading AIS(accounting information system) have focused on studying the effect of the quality factors of AIS on user satisfaction, user intension, performance on the basis of TAM and TPB. In this paper, we conduct a comparative study on the effect of the quality factors of AIS on business performance and the meditation effect of user satisfaction in relation between the quality factors of AIS and business performance for Korea and China. The results of this study are as follows. First, the impact of the quality factors of AIS on business performance is not significant both in Korea and in China. Second, the results of the analysis of the mediating role of user satisfaction in the relationship between the quality of AIS and business performance is different between Korea and China. Finally, the analysis of difference in path coefficients between Korea and China structural equation models shows a significant difference. In order for user satisfaction to play a mediating role in the relation between quality factors of AIS and business performance, it is necessary not only to computerize the process of producing information in companies, but also to ensure the quality of information and secure the abundant information. In addition, the quality of AIS should be continuously and consistently managed in order to improve user satisfaction.
