| The occurrence of social hot events has caused fluctuations and changes in public mood,while the rapid development of online social platforms and networks has made public interaction more intense and further promoted the fermentation of panic.The outbreak of COVID-19 at the end of 2019 has had a significant impact on the normal life of people all over the world,and negative information related to this epidemic was rapidly disseminated,triggering anxiety and panic among people.At the same time,these negative emotions were further spread online through social networks,forming a network of public opinion,which was gradually derived to the offline environment,triggering a mass panic buying.This not only seriously endangers public health and social stability,but also has a great negative impact on national security and economic development.This paper focuses on the typical public health emergency COVID-19,and studies the panic buying phenomenon.The specific contents are as follows:In this paper,an evolutionary game model for the development of panic buying events in COVID-19 is constructed by researching on the dynamic process of the public and the government adjusting their strategic choices and playing a continuous game.This paper uses regret theory to depict the public’s perceived value of the items in the panic buying situation,describes the characteristics of each stage of the rumors spreading process and the evolution process of panic buying events,and introduces the variable of public critical ability to measure the public’s panic buying willingness.The evolutionary process of public mask panic buying behavior was analyzed and the simulation results were analyzed.The results show that the government’s intervention measures according to the characteristics of different stages can effectively control the continuous fermentation time and influence the scope of panic buying events.The implementation of the government’s rumor-refutation strategy will also significantly affect the volume of public panic buying,which will help the government timely understand the public’s epidemic prevention needs in COVID-19,relieve public panic,and provide a basis for the effective management and scheduling of emergency supplies.Finally,from the government’s perspective,a three-stage intervention strategy of pre-preparation-response-post-improvement of the robbery event is proposed. |
