Abstract: Based on motivation-competence framework， this paper adopts the method of qualitative comparative analysis of multivalued sets to explore the internal mechanism of local governments' choice of compromise response or gradual response in the process of not in my back yard events. The response strategies of local governments are rooted in the four element interaction of interest preference， avoiding accountability risks， resource integration ability and communication and coordination ability. Economic benefit projects can stimulate local governments to choose a gradual response path better than public welfare projects. Vertical support and horizontal integration can effectively promote local governments to choose a progressive response. The relatively silent potential beneficiaries of the project should be an important parameter to measure the value of the project. In order to avoid falling into the strange circle of “project implementation-public opposition-conflict escalation-suspension of construction”， local governments should shift from rigid stability maintenance to resilient stability maintenance， realize the two-way transformation of interest preferences through the whole process negotiation and communication mechanism， and achieve the balance of the dual values of social harmony and regional development through the vertically and horizontally connected resource cooperation network.

Key words: not in my back yard event; government response; motivation-competence framework; qualitative comparative analysis (QCA)
