Social commerce (s-commerce) has gained prominence with advances in social media and social networking technologies over the last decade. Prior research has employed diverse theoretical perspectives to understand and explain consumer behavior within s-commerce but has also produced inconsistent results. This study integrates different theoretical perspectives including trust, social support, and social presence. The research portrays an integrated research model involving factors that impact behavioral intention and use behavior of s-commerce consumers whilst synthesizing prior empirical findings. A meta-analytic structural equation modeling (MASEM) method was used to synthesize 189 findings reported in 68 s-commerce studies and to analyze the structural model. Our findings show that trust and informational support have positive effects on behavioral intention while trust and emotional support have positive effects on use behavior. Furthermore, our findings highlight that behavioral intention influences use behavior and mediates the effect of trust and informational support on use behavior. The implications for research and practice are discussed in detail.

社交商务（s-commerce）在过去十年中随着社交媒体和社交网络技术的进步而变得突出。先前的研究采用了不同的理论视角来理解和解释电子商务中的消费者行为，但也产生了不一致的结果。本研究整合了不同的理论观点，包括信任、社会支持和社会存在。该研究描绘了一个综合研究模型，涉及影响电子商务消费者的行为意图和使用行为的因素，同时综合先前的实证结果。元分析结构方程模型 (MASEM) 方法用于综合 68 项电子商务研究中报告的 189 项研究结果并分析结构模型。我们的研究结果表明，信任和信息支持对行为意向有积极影响，而信任和情感支持对使用行为有积极影响。此外，我们的研究结果强调，行为意图会影响使用行为并调节信任和信息支持对使用行为的影响。详细讨论了对研究和实践的影响。
