Abstract:

In order to solve the problem of people's panic buying of emergency protection materials in public health emergencies, as well as the derived problems such as imbalance between supply and demand, uneven distribution, skyrocketing price and uneven quality, a game model involving the government, enterprises and the public is constructed based on the evolutionary game theory. Considering the influence of panic emotion on panic buying behavior, the paper first describes the value of people's material purchase under panic emotion. Then, based on the characteristics of the model, the evolution mechanism between different participants is discussed by using the nonlinear system theory, and the equilibrium point and stability of the game under different situations are obtained. Finally, the influence of different panic intensity on the behavior evolution of participants is further analyzed through simulation. The research results can provide some reference for the evolution mechanism of emergency protection material management in public health emergencies.

Key words: panic, emergency protective materials, evolutionary game, nonlinear system theory
