| The comprehensive implementation of the river chief system is a major institutional innovation made by the CPC Central Committee to accelerate the construction of ecological civilization and promote the harmonious coexistence between man and nature.Since the establishment of the river chief system in June 2018,the river chief system has achieved full results and become the only way to win the battle against clear water.How to effectively improve the governance performance of the river chief system is an important issue that needs to be addressed at this stage.Most ethnic minority areas have beautiful mountains and rivers,and have good ecological resources endowment.In the process of social development,the importance of ecological environmental protection has become increasingly prominent.Therefore,it is of great significance to deeply explore the mechanism affecting the governance performance of river chief system in minority areas and promote the construction of ecological civilization in minority areas with the new achievements of river and lake governance,so as to realize the maximum transformation of ecological resource advantages into economic advantages in minority areas.Governance performance is the product of the combined action of many complex factors.Most of the existing studies used linear thinking to explore the marginal "net effect" of a single variable on the governance performance of the river chief system,but lacked the comprehensive mechanism of action of multiple antecedent conditions on the governance performance of the river chief system from a holistic perspective.Based on the holistic perspective,qualitative comparative analysis method(QCA)integrates the advantages of qualitative research and quantitative research in the traditional research paradigm,and can fully explore the influence mechanism of synergistic interaction of two or more antecedent conditions on the governance performance of river chief system.Therefore,this study introduced QCA into the governance performance study of river chief system.12 counties(cities)in Dali Bai Autonomous Prefecture of Yunnan Province were taken as research samples.Based on TOE theoretical framework,five antecedence conditions,namely,technical factors(construction of technical facilities),were selected from the three dimensions of technology,organization and environment.Organizational factors(supply of financial resources,allocation of government attention);Environmental factors(economic development level,river and lake governance pressure).Meanwhile,the third-party evaluation results of the river chief system in 12 counties(cities)of Dali Prefecture were selected as the outcome variables of governance performance,and the analysis framework of the river chief system governance performance of Dali Prefecture was constructed.The fuzzy set qualitative comparative analysis method(fs QCA)was used to explore the antecedent configuration leading to the governance performance of the high river chief system in Dali state,and the equivalent driving path and the equivalent replacement mechanism between the antecedent configuration of the governance performance of the high river chief system in Dali state were summarized,and the corresponding typical cases were analyzed.The results show that:(1)A single antecedent condition does not constitute the necessary condition for the governance performance of the high river chief system in Dali prefecture.(2)There are three equivalent driving paths for the governance performance of the high river chief system in Dali prefecture,namely,the governance pressure dominant type,the technology-organization dual core type and the technology-organization-environment coupling type.(3)The effective combination of technology,organization,environment and other factors can lead to the governance performance of the high river chief system in the way of "common destination" through the effect of "equivalent substitution".That is,when the level of technical facilities is high and the government’s attention is distributed strongly,as long as the local government has strong financial supply capacity,or the regional economy develops well and there is certain pressure of river and lake governance,the governance performance of the high river chief system can be produced.The theoretical contribution of this study is as follows: based on TOE framework,it constructs an integrated analysis framework of influencing factors of the governance performance of the high river chief system in Dali prefecture,reveals the complex causes of the governance performance of the high river chief system in Dali Prefecture,and analyzes the synergistic and concurrent effects and equivalent alternative mechanisms of the multiple conditions such as technology,organization and environment in explaining the governance performance of the high river chief system.The practical enlightenment for the future is that the inherent "causal monotonicity" concept should be abandoned in river and lake governance in ethnic minority areas,and a new perspective of "causal complexity" should be accepted.Based on the practice and resource endowment of river and lake governance in ethnic minority areas,appropriate institutional pressure should be implemented,so as to comprehensively improve the river and lake governance capacity in ethnic minority areas.At the same time,this study also has some limitations: given the availability of data,the number of research samples is limited to a certain extent;The model construction of influencing factors of river chief governance performance needs to be optimized;The time factor is not included in the causality analysis of river chief system governance performance. |
