Abstract: Based on 5,860 data collected from 39 surveys at home and abroad, this paper adopts Meta-analysis method to study the safety climate and managers' commitment in chemical enterprises from the perspectives of conformity behavior, social cognition and organizational support theory. It is found that safety communication, safety environment, safety supervision and other factors have a significant positive effect on employee safety behavior, and the mediating effect of enterprise size and the number of dimensions of safety climate on employee safety behavior is also investigated. The results indicate that the safety climate as a whole and all levels have a significant positive impact on employee safety behavior, while the management commitment and safety communication have a moderate impact on employee safety behavior. Enterprise size and the number of safety climate dimensions have obvious effects on the relationship between employee safety climate and employee safety behavior. Among them, there is no direct correlation between the number of enterprise safety climate and the effect value of each dimension.
