ABSTRACT Online group-buying has emerged as a new e-commerce model and received attention in both academics and practice Prior researches focused on investigating online group-buying mainly from the marketing perspective, such as the transaction process, price mechanism, and benefits (Li & Liu, 2012) Few of studies have investigated the relation between consumer’s acceptance and their purchasing behavior Hence, this study focuses in measuring relationship between cognitive factors – trust, satisfaction and perceived usefulness – and online group-buying repurchase intention Simultaneous, this study also integrates website quality - a direct and indirect variable – to measure its impact on customer repurchase behavior To examine research model, information and data is accessed by using questionnaire for respondents more than 18 years old and have ever purchased on online group-buying websites Sample size of this quantitative research is 365 respondents Confirmatory factor analysis (CFA) is used to test measurement scale and the structural equation modeling (SEM) is used as the main method for analyzing research model and hypotheses Results in this study show that individual user’ intention to repurchase in online group-buying websites is motivated by trust, satisfaction and website quality Among three impact factors, website quality has the strongest direct influence, followed by trust and satisfaction Besides direct influence, website quality also has indirect impact on customer repurchase intention through both of trust and satisfaction Trust also has strong impact on customer satisfaction, thus, affect indirectly to customer retention With these results, research framework can be seen fitted with data market Study results also suggest that in order to increase customer retention should not only consider about their strategies of increasing trust and satisfaction, they should also take consideration of increasing website quality, especially in content quality and technical adequacy Chiu, C.M., Hsu, M.H., Lai, H., Chang, C.M (2012) Re-examining the influence of trust on online repeat repurchase intention: The moderating role of habit and its
