This study constructs a theoretical model to explain the relationship between religious belief, environmental perception, network use and individual pro-environmental behavior. The largest comprehensive social survey data in China provides empirical support for our theoretical model. Our empirical results indicate that individual religious belief is negatively related to their pro-environmental behavior in which individual environmental perception and network use play a partial mediating role. Besides, our model explains whether and why religious beliefs exist in individuals' pro-environmental behaviors, which contributes to both theory and practice.
