The spread of the COVID?19 had exposed many problems in China’s response to public health emergencies， including the lack of an emergency response mechanism， the near?paralysis of the epidemic monitoring and early warning system， the lack of an epidemic emergency information system， the insufficient stock of emergency supplies for epidemic prevention and the lagging management as well as the lack of medical emergency drills. Considering the status quo of Jiangsu Province，the authors found that the emergency command coordination linkage mechanism for public health emergencies should be further strengthened， the epidemic monitoring and early warning mechanism should be continuously improved， and the epidemic emergency information sharing mechanism should develop. The emergency material management and supply guarantee mechanism for the epidemic should to be improved urgently， and the emergency drill mechanism for public health emergencies should to be established first. To this end， the suggestions are as follows: raising awareness and speeding up the formation of consensus on improving the emergency response capabilities of public health emergencies； improving the province’s emergency response mechanism for public health emergencies from the entire emergency management process； building the Jiangsu epidemic monitoring and early warning system and improving its operating mechanism； designing epidemic emergency information system to promote information sharing； constructing an emergency material management，supply guarantee and information system for major epidemics； establishing and improving the operational mechanism of emergency drills for public health emergencies，and broadening ideas and innovating the training model of health emergency personnel.
