ABSTRACT

Rural PPP infrastructure and the "Thousands of Enterprises Assist Thousands of Towns" corporate assistance policy are two core public-private governance tools for China's rural revitalization. Existing literature studies PPP performance and corporate rural support separately, ignoring their interactive synergies within the same county governance system. This paper constructs two subsystems: rural PPP comprehensive performance subsystem and local enterprise ESG assistance subsystem. Based on cross matching of 58 counties with rural PPP projects and corresponding 170 paired assistance enterprises in Guangdong Province, this paper adopts entropy weight method to calculate subsystem composite scores, applies coupling coordination degree (CCD) model to measure county-level synergistic coupling levels, and further uses grouped regression to identify heterogeneous driving factors of coupling efficiency across county economic tiers and project types. The results show that most sample counties stay in moderate coupling stage; counties with wetland cultural PPP and manufacturing enterprise groups own significantly higher coordination degree; county fiscal capacity, public participation governance and industrial matching degree are core positive driving factors, while single capital-oriented assistance and sanitation PPP restrict coupling promotion. This study innovatively matches two independent micro datasets into county-level cross-section samples, supplements the interactive governance logic of dual public-private tools, and provides classified collaborative optimization paths for county rural revitalization governance.
