Urban environmental issues are fundamental to ecological civilization development, with key stakeholders such as governments, enterprises, social organizations, and community residents playing crucial roles in the governance process. From a network governance perspective, this study innovatively applied social network analysis (SNA) to policy co-occurrence networks, analyzing over 2300 policy documents related to China’s urban environmental governance from 2017 to 2023 to investigate evolutionary trends. The key findings indicate the following. (1) The comparative analysis across two periods reveals that China’s urban environmental governance network structure has stabilized, with both network density and centralization indices showing an upward trend. (2) The degree of centrality and betweenness centrality shows that government agencies remain the core entities within the network, while the role and influence of business enterprises have steadily increased. (3) The participation of social organizations in governance continues to increase, but community public participation in governance is insufficient. Therefore, China’s ecological environment governance network has formed a network structure with the government as the leader, enterprises as the key role, and social organizations providing effective support.
