英文摘要：

Understanding consumers＇ behavior in social commerce is critical for companies to ef- fectively capitalize on the power of social relationships and influence them. Based on the stimulus-or- ganism-response paradigm and social exchange theory, this study builds a fruit consumers＇ decision behavior model to explore the effects of social commerce characteristics on social support and purchase intention. The empirical results find that interactivity, stickiness and word-of-mouth referral have positive impacts on information support and emotional support, and among them word-of-mouth refer- ral is the largest one; Information support and emotional support positively enable the prediction of purchase intention, furthermore both of them exist partial mediating effects, indicating the intrinsic mechanism of the effects of social commerce characteristics on purchase intention.
