| Protecting the ecological environment and controlling pollution are the embodiment of government functions.As a public product,the ecological environment is often prone to "tragedy of the commons" or "prisoner’s dilemma" in the process of management.Regional pollution control often involves two or more subjects.And the treatment of river basin pollution is more typical because the water flow has the characteristics of fluidity.In the 1870 s,developed countries such as Europe and the United States began to try the coordinated management of river basins and achieved certain results.China has begun to try the coordinated governance of river basins in different regions in the past two decades.But it still has great differences between China and Western capitalist countries in terms of social conditions and public opinion,the ways,methods and means of coordinated governance due to the implementation of territorial management mode.Therefore,more exploration and attempts need to be made in river basin governance.This study takes the case of collaborative governance of Tongbo River between Dazhou,Sichuan and Liangping,Chongqing as the object,focuses on the case of joint governance of Tongbo River between two cities with different administrative levels and different administrative forces in the Chengdu-Chongqing economic circle,and deeply analyzes the reasons for the success of the case by using the theory of tragedy of the commons,the theory of collaborative governance and the theory of intergovernmental management,and using the research methods of literature research and case study,this paper deeply analyzes the reasons for the success of the case,and looks for the key factors in the process of collaborative governance of Tongbo River in Dazhou,Sichuan and Liangping,Chongqing.Combined with relevant data and investigation and analysis results,this study has the following findings: firstly,building a collaborative cooperation mechanism is the premise for the success of the two places’ collaborative governance of Tongbo river.Secondly,the coordinated adjustment of industrial structure is the key link to promote the governance of Tongbo River Basin and eliminate the root causes of pollution.Thirdly,improve the material basis of collaborative governance to provide guarantee for the sustainable development of Tongbo River governance.Therefore,the construction of cooperation mechanism,adjustment of industrial structure and improvement of infrastructure are important factors for Dazhou and Liang Ping to break through the old model of fighting alone and promote the success of coordinated governance of Tongbo river.There are two innovations in this study.Firstly,Dazhou,Sichuan and Liangping,Chongqing jointly control Tongbo River as a pilot of pollution control,while promoting the construction of the Chengdu-Chongqing economic circle,it deeply summarizes the key factors,and forms a beneficial experience for the coordinated treatment of ecological environment in Sichuan and Chongqing;Secondly,for the inter governmental collaborative governance under the conditions of unequal administrative levels and differences in administrative forces,this case can provide reference experience for breaking through the institutional obstacles and creatively carrying out inter regional collaborative cooperation to a certain extent. |
