ever increasing Many of these online stores, however, fail for some reasons Research indicated that one of the main reasons is that consumer‟s not trust online retailers How to increase consumers‟ trust has become an important issue in social commerce A theoretical model was derived based upon previous studies and the technology acceptance model (TAM), and nine hypotheses were proposed to examine the relationships between constructs Survey method was employed for collecting data from 163 valid respondents in Viet Nam For testing theoretical hypotheses, structure equation modeling (SEM) was conducted using maximum likelihood estimation in SmartPLS Theoretical contributions and practical implications on the finding were discussed and suggestions for future study were presented
