Fig. 1: Conceptual SES framework.

The green boxes represent the three core subsystems in the conceptual SES framework: resource systems and units (RSU), which include ecological factors; governance systems (GS), which include institutional factors; and actors (A), which include social factors. The blue boxes represent the interaction factors that may emerge from the interaction between factors within the three core subsystems. These interaction factors may play a mediating role in the process where institutional-social-ecological factors influence the quality of public open space. The green arrows represent the pathways through which institutional-social-ecological factors influence interaction factors, while the bule arrow represents the pathway through which interaction factors influence the quality of public open space. The red box represents the quality of public open spaces, which is the dependent variable in this study. It is used to measure the self-governance performance of rural POSs in China.
