Abstract: Aiming at the problem of frequent production safety accidents occurring in chemical industry, especially major and particularly serious production safety accidents in recent years and based on game theory, the game model was constructed with the profits of the chemical enterprises and the benefits of safety supervision departments as the targets. A dynamic game analysis was carried out on the safety investment of chemical companies and the supervision of safety supervision departments. Then Nash equilibrium of the mixed countermeasures was presented. And an in-depth research and analysis on the evolution process of both sides of the game was carried out. According to local stability analysis, the evolutionary strategies of both sides of the rational game are related to the benefits of both sides, the cost, the probability of accidents and the economic loss in an accident under certain conditions. The research conclusions provide recommendations for the rationality and effectiveness of the safety in production in chemical companies and the supervision of safety supervision departments.
