An Empirical Study Of Seller-Dominitated B2B E-Commerce Sysytems Acceptance Model

More and more domestic corporations regard B2B E-commerce as an effectual way to enhance their competitive advantage in recent years. However, the fact that most information systems which cost huge expenditure, such as ERP, SCM or CRM, leaved unused puzzles administrators and researchers.The low usage level of information systems remains a focus in IS research area. Abundant literatures concerned this issue have emerged since 1980s and many valued conclusions had been acquired. In the mean time the research objects had shift from simple application programm, such as WORD, EMAIL, to complicated information systems like ERP, IOS etc. However, there are still few literatures which study user acceptance of information systems in China mainland. The existing research about B2B E-commerce remains in technology issues such as B2B standards or website structure.In this theoretical and practical background, this thesis bases on Technology Acceptance Model (TAM), and introduces social variables ,culture variables, inner-organization variables and behavior perception variables, in order to find out the factors which significantly influence the user acceptance action about Seller-dominated B2B E-commerce Systems of Chinese companies. Then, the thesis conducts an empirical study to validate the theoretical Seller-dominated B2B E-commerce Systems Acceptance Model (SBESAM).During the stage of model creation, the research was perfomed in the following process. Firstly, the relationship between buyer and seller was analyzed from the perspective of Transction Cost of Economics. Secondly, a literature review about the foundation and the development of TAM had been made. Finally, the SBESAM was created based on TAM by adding four external variables and one perception variables.During the stage of empirical study, the research was perfomed in the following process. Firstly, a questionnaire was designed based on other researcher's scales. Secondly, in order to validate the reliability and validity of the questionnaire, a pretest had been carried on and the questionnaire was revised. Finally, data processing was performed by regression analysis as well as Structure Equation Model (SEM), and a result comparison was made between them.The empirical study found that the major influenced external variables are Subjective Norms, Job Relevance and Response Time. Subjective Norms have a significant impact on Behavior Intention among buyer's users but not seller's users. Job Relevance has a positive effect on Perceived Usefulness and Response Time has a negative effect on Perceived Reliability. Regression analysis suggested that Perceived Reliability may actually be a causal antecedent to Perceived Usefulness, rather than a direct determinant of Behavior Intention. The SBESAM was strongly supported by two methods of data processing, accounting for about 50% variance in usage intentions and about 60% usefulness perceptions.Basing on the result of SBESAM, the thesis raises several advices to the Chinese enterprises that use B2B E-commerce, for the purpose of helping them to make some improvements on the B2B E-commerce implement process.
