Abstract: The Central Environmental Protection Inspection is an important system of "supervision" in the environmental field. Its direct object is the environmental governance behavior of the local government. The behavior of the local government is the result of a comprehensive interweaving of multiple factors in the two dimensions of motivation and constraint. Based on this, this paper starts from the motivation and constraints of local government's pollution control behavior, and builds an analysis framework of the local environmental governance mechanism under the pressure of the central environmental protection inspection. Taking 30 cases inspected in 2018 as the research objects, the fuzzy set qualitative comparative analysis method (fsQCA) is adopted to explore the complex mechanism of the interaction of six conditional variables of pressure and constraint on local environmental governance behavior. The results show that there are two paths for the occurrence of local environmental governance behaviors:①Environmental protection pressure-driven mode, environmental pressure is the key factor in the occurrence of local environmental governance behavior; ②Inflection point model, economic constraints and resource constraints are important for local environmental governance behaviors Influencing factors. Based on the above analysis, this paper proposes that policies should be aimed at improving the local government's ecological performance evaluation system, improving the transfer payment system and fiscal and taxation policies in the field of environmental governance, and improving the public participation mechanism.

Key words: Central Environmental Inspection, local government pollution control behavior, behavioral motivation, constraint conditions, fu zzy-set qualitative comparative analysis
