In order to provide references and suggestions for the future development and improvement of public health emergency management policies, the existing public health emergency management related policy texts in a multi-dimensional way was analyzed, and text mining was conducted on the policy texts related to public health emergency management issued at the national level in China from 2003 to 2023, and typical policy samples were selected to construct a PMC index evaluation model for public health emergency management policies. The evaluation system of PMC index model consists of 10 first-level variables and 38 second-level variables, and there exist 3 grades of policies as a whole, 1 qualified policy, 10 good policies, and 4 excellent policies. At this stage, the emergency management policy system for public health emergencies is basically perfect, but it still needs to be continuously optimized and improved in the future. It is recommended to reasonably divide the policy time limit, build a multifaceted and coordinated emergency management mechanism, and accurately implement policies in order to realize the all-round and precise management of public health emergency management.
