Purpose/Significance Clarify the differentiated impacts of government policy regulation and behavioral regulation on residents' environmental participation, and reveal the moderating role of environmental cognition, providing empirical evidence for the formulation of targeted environmental governance policies.

Method/Process Based on the CGSS 2018 data, principal component analysis (PCA) is used to reduce the dimensionality of relevant variables. An OLS model is employed to explore the impact of government policy regulation and behavioral regulation on residents' environmental participation behavior, and to analyze the moderating effect of environmental cognition. Additionally, robustness checks are performed through reduced sample regression and regression with added control variables. Propensity score matching (PSM) is used to address the issue of endogeneity.

Results/Conclusion Government policy regulation and behavioral regulation both significantly promote residents’ environmental participation behavior. Before incorporating the interaction of moderating variables, the impact of behavioral regulation is stronger. Environmental cognition has a positive moderating effect on both policy regulation and behavioral regulation, and its moderating effect on policy regulation is greater than that on behavioral regulation.
