With its efficient resource integration and scale advantages, luxury e-commerce platforms are gradually becoming the mainstream trend of luxury online transactions. At present, sharing, interaction, and social networking have become essential elements of the Internet platform. More and more consumers tend to learn from the users on the Internet to share the product information they need and make shopping decisions. This article divides the sharing of community application users into four dimensions, and studies how they influence consumers' willingness to purchase through user-generated content (UGC), perceived usefulness and para-social interaction. It uses the RED platform as a case study. This research uses the quantitative analysis research method. About 250 questionnaires were obtained via online channel. Then, the data were analyzed and presented using descriptive analysis, reliability and factor analysis, and structural equation modeling (SEM) to draw relevant conclusions and recommendations.
