Predicting intention to purchase on group buying website in Taiwan: Virtual community, critical mass, and risk

Purpose – This study proposes integrating the perceived risk and social influence literatures on online group buying (OGB) intentions with the basic TAM variables (perceived usefulness and perceived ease of use).Design/methodology/approach – Based on an empirical survey of 304 online adopters of OGB in Taiwan, the paper uses structural equation modeling to confirm the research model.Findings – The results reveal that perceived critical mass had the largest total effect on intention to use group buying websites. The findings also indicate that perceived usefulness and a sense of virtual community (SOVC) have significant effect on OGB intention. In addition, both perceived ease of use and website quality influence perceived usefulness. As expected, perceived risk has negative effect on OGB intention.Research limitations/implications – This study only considered buying intention with regard to foodstuffs, and it is unclear whether these analytical results can be generalized to other items.
