Abstract: Based on the theory of collaborative governance, focusing on prefecture-level cities in non-nuclear facility provinces in the central region, and taking the coordination mechanism of nuclear and radiation emergency response as the research starting point, this study systematically reviews the current operational status of the collaborative emergency response mechanism in a specific prefecture-level city, and analyzes the structural challenges and unique risk characteristics it faces in actual responses. On this basis, it proposes a coordination path for the in-depth integration of nuclear and radiation emergency preparedness into the regular "comprehensive emergency" management system, and constructs an appropriate performance evaluation system. The purpose of this research is to improve the systematicness and response efficiency of grassroots emergency management, promote the realization of the goal of "rapid response and efficient handling", and provide a reference for similar regions to improve their nuclear and radiation emergency coordination mechanisms.

Key words: nuclear and radiation emergency, coordination mechanism, performance evaluation, public communication
