The Evolutionary Game Model for Air Pollution Collaborative Governance from the Perspective of Multidimensional Heterogeneity
Collaborative governance of regional pollution breaks the postulate of homoge-neous entities in traditional governance of regional pollution,throwing new challenges to the research of regional pollution governance.Hence,based on multiple heterogeneous dimensions,this study constructs the indicators of collaborative capacity of pollution governance among local governments according to four dimensions of pollution governance capacity,preferences,rate of pollution spillover and government revenue.Meanwhile,we make an evolutionary analysis of the strategic choices of local governments based on the constructed indicators to explore the rules of local governments'action evolution and driving factors in collaborative governance.The main results show that:(1)Local government's capacity of collaborative pollution governance is the key factor in the collaborative abatement of transboundary pol-lution;(2)Over-heterogeneous dimensions among local governments,such as territorial gov-ernance capacity,inclination,rate of pollution spillover and government revenue,can readily forge race-to-top competition relationships among governance entities,doing harm to the con-struction of trust in each other during the collaborative governance of air pollution;(3)The spillover effect of air pollution form a high correlation of benefits between entities and directly affect the comprehensive revenues of local governments,thereby influencing their strategy preferences during the collaborating process.Finally,through simulation analysis,some coop-erative countermeasures for inter-government air pollution management from the perspective of multidimensional heterogeneity are given to promote regional pollution control out of the dilemma of coordination and achieve good coordination.
