Abstract: COVID-19 outbreak and other major crisis events have brought severe challenges to the life and health of Chinese people. The serious imbalance between supply and demand of mobilized resources such as medical materials has become a problem for effectively coping with major crisis events. Based on the analysis of the demand for mobilized resources in time of emergency, war and peace, the historical context of the formation of the supernormal supply school was introduced, the relationship between the supernormal supply theory and the western supply school and supply-side structural reform in China was compared, the framework of the supernormal supply theory was put forward, and its characteristics were summarized. The research shows that the theory of supernormal supply is an important supplement and improvement to the theory of supply-side structural reform of China. It is mainly used to solve the contradiction between supply and demand in crisis situations during emergency, wartime and serious market imbalance. Its core idea is to provide stable supernormal supply capacity for coping with crisis.
