By analyzing the scientific rationality and existing problems of emergency information management policy tools,this paper finds the direction to be improved, and provides effective policy reference for future policy adjustment and optimization. [Method/process] Based on the content analysis method, starting from the supply-oriented, environment-oriented and demand-oriented policy tools, and combined with the functional dimensions of public health emergency information, namely, pre-event information monitoring and early warning, in event information sharing and decision-making, post event information traceability and application, and whole process information management, this paper constructs a two-dimensional analysis theoretical framework to analyze China's public health emergency information from multiple perspectives. Then the current situation of public health emergency information management policy,the scientific rationality of policy tools and existing problems were discussed. [Result/conclusion] when optimizing the policy system of emergency information management in the future, the government should increase the proportion of de?

mand-oriented policy tools, optimize the use of supply-oriented and environment-oriented policy tools, enhance the synergy between policy tools and functional dimensions, and improve the effectiveness and management ability of emergency information management policies.
