Research on the diffusion and control of unsafe behaviors among chemical industry park enterprises based on the SEIR evolutionary game model

Abstract

In order to control the diffusion of unsafe behaviors among chemical industrial park enterprises, a Susceptible-Exposed-Infectious-Recovered (SEIR) evolutionary game model is constructed based on the theory of epidemiology and evolutionary game theory. By exploring the game relationship between emergency management departments and safety assessment agencies, the paper analyzes the diffusion paths and evolutionary patterns of unsafe behaviors in chemical industrial park enterprises under different behavioral strategies adopted by both parties. Furthermore, it examines the process and patterns of system evolution to a positive stable state, and conducts multi-scenario simulation and analysis. The results indicate that the interactive behaviors of "strict regulation" by emergency management departments and "high-quality safety assessment" by safety assessment agencies are more conducive to controlling the diffusion of unsafe behaviors among chemical industrial park enterprises. Improving the efficiency of emergency management departments, establishing an attractive and constraining reward and punishment system to guide safety assessment agencies in conducting high-quality safety assessments, and stimulating the initiative of chemical industrial park enterprises in safety behaviors will be more conducive to forming an integrated, coordinated, and mutually constraining mechanism for work safety governance.
