It is a serious torture of the relationship between man and society, and between man and nature. It is a severe test to advance the modernization of the national governance system and capacity. It also poses greater challenges to the existing emergency response mechanism. Nowadays, the ability of governments at all levels to deal with various emergencies more and more has become one of the important indicators to measure the governance capacity of a government. In the new era, the people's demand for public safety is increasing, and their tolerance for security risks is getting lower and lower, which places new and higher requirements on emergency management. In this study, combined with the ten types of emergency mechanisms of modern emergency management, the actual situation and outstanding problems of China's CoViD-19 epidemic emergency are analyzed, and the emergency mechanism is studied systematically and empirically. Specific analysis opinions and strategies are put forward to provide reference for decision-making.
