In this time, social media are widely used by the general public. This study mainly explores the influence of the sense of belonging and social anxiety on consumer experience, and uses social media as an intermediary role, and social involvement as an interfering social media to consumer experience effect. Most researches have pointed out that the sense of belonging and social anxiety has always been a very important research topic, but few articles currently discuss the impact of the sense of belonging and social anxiety on consumer experience, so in order to make up for this gap, this research hypothesis is proposed. The main research objects of this study are the young and middle-aged people who use Facebook, and they used the intention sampling survey to collect data. The empirical results show that: 1. The sense of belonging has no significant impact on social media. 2. Social anxiety has no significant effect on social media. 3. Social media has positively influenced consumer experience. 4. Lower social engagement will increase the influence of social media on consumer experience.
