The results show that: 1) Anchor professionalism can indirectly influence rural residents' online consumption behavior through perceived usefulness and perceived trust; the quality of commodity information can directly influence rural residents' online consumption behavior, and can indirectly influence rural residents' online consumption behavior through perceived usefulness and perceived trust; the live E-commerce interactivity only has a direct influence on rural residents' online consumption behaviors; 2) Perceived usefulness has a significant positive impact on perceived rust; 3) With different gender, educational level and annual income level, rural residents' internal perception reacts differently to external stimulus, which results in different online consumption behaviors.
