Resumen
Drawing on social identity theory, this study aims to examine the impact of antecedents of eWOM on the online purchase intention (OPI) of fashion-related products. In addition, social media usage moderates the relationship between eWOM and OPI. A structured questionnaire was completed by a sample of 477 Chinese WeChat users. An online survey was conducted in two metropolitan cities (Beijing and Shanghai). The hypotheses were tested using structural equation modeling (SEM) generated by AMOS 22. The findings of this study found that all five antecedents of eWOM, such as fashion involvement, sense of belonging, trust, tie strength, and informational influence, positively related to the OPI of fashion products in China. Furthermore, eWOM significantly mediates the relationship between fashion involvement, sense of belonging, trust, informational influence, and OPI. The current study is considered the first to examine the role of eWOM in stimulating OPI through social media usage for fashion-oriented products in China. As such, it enriches the online buying literature by exploring the OPI mechanism through eWOM antecedents and validating the importance of social media factors in the development of online buying intention compared to previous studies. Furthermore, it provides several theoretical and practical implications, along with future opportunities.
