Based on CGSS2015 data, this paper analyzes the influence of religious belief on the identification of rural residents. The empirical results show that religious belief has a significant positive impact on the class identity of rural residents. Rural residents with religious beliefs were more likely to have a higher level of class identity than those without religious beliefs. Specifically, religious belief plays a role through participation effect, taste effect and consolation effect. Participation in religious activities has a significant positive impact on the class identification of rural residents, and the higher the participation frequency, the stronger the positive impact; Different religious belief types all have positive effects on the identification of rural residents, but the degree of influence is different, only Islam has statistical significance; Compared with local religious belief, foreign religious belief will enhance the identification of rural residents to a greater extent; Compared with rural residents with better family economic status, religious belief has greater influence on rural residents with poorer family economic status.
