Abstract: Domestic waste sorting is an important part of promoting good governance in cities The phenomenon of “different appearance in the same city” often occurs in the implementation of waste sorting policies in various cities, and residents’ random throwing, middle-end mixed transportation and back-end ineffective disposal occur from time to time The operation performance of the front-end of waste sorting is emphasized Based on the construction of the performance evaluation model of domestic waste sorting policy, N city is selected as the analysis sample to evaluate the operation performance of the policy, and csQCA and other analysis tools are used to explore the factors affecting the operation performance of the front-end of domestic waste sorting policy The results show that the introduction of new technologies, the stock of social capital and the convenience of sorting facilities are the core factors affecting the front-end operation performance; Communication and mobilization are marginal factors; Economic interaction has an insignificant effect on the good performance It is believed that to optimize the front-end operation performance of domestic waste sorting, different subjects should be introduced to build interactive networks, social capital should be accumulated to promote effective participation, and science and technology should be better used to realize intelligent sorting.
