Abstract: Public health emergencies are a serious challenge the world is faced with. Fighting against the COVID-19 is a big test of the emergency response and governance capabilities of the countries around the world. Under the solid leadership of the Party Central Committee with Xi Jinping as the core, China has made great achievements in fighting against the epidemic and won the widespread recognition of the international community. However, during the course of fighting against the epidemic, some weaknesses in the emergency management of public health emergencies have been exposed, and it is necessary to use systematic thinking to find out the differences, make up for shortcomings, and plug loopholes. As for the improvement of the system construction of relative laws and regulations, such laws and departmental regulations as “The Public Health Emergency Response Act” , “The Biosecurity Law”, “The Public Health Risk Early Warning Management Measures” and other relevant laws and regulations should be formulated as soon as possible, and relevant supporting laws and regulations should be revised. Reform and innovation should be carried out in improving the emergency command system, the prevention and warning system, the treatment system, the information dissemination system and other aspects. Great efforts should be made to build a long-term and effective mechanism for emergency management of public health emergencies with Chinese characteristics.

Key words: public health emergencies, COVID-19, systematic thinking, emergency management
