Although people have extensively studied the influencing factors of pro-environmental behaviors (PEBs) on individuals and society, there is still a lack of a unified and reasonable explanation among individuals, society, and nature. We explore the relationship among social class cognition (SCC), public service satisfaction (PSS), environmental risk perception (ERP), media use (MU), and citizens’ PEBs. Structural equation modeling (SEM) was used for evaluating the causal chain from SCC, PSS to citizens’ PEBs in the Chinese General Social Survey 2013 (CGSS2013, n=673), and the mediating role of ERP in the transition from SCC, PSS to citizens’ PEBs. The results show that SCC and PSS significantly influence citizens’ PEBs. From the perspective of impact mechanism, ERP plays an important mediating role in the impact path of SCC and PSS on citizens’ PEBs. ERP is constantly spread, diffused, and enhanced by MU, and contributes to the formation of citizens’ PEBs. This research is helpful to get a reasonable explanation of PEBs in individual-society-nature, and thus break the boundary between the private sphere and the public sphere to form an environmental governance pattern of co-construction, co-governance, and sharing.
