Evolutionary Game Theory-Based Modeling and Stability Analysis of Subsidy Policy on Safety Investment in SMEs

Evolutionary game theory originated as an application of the mathematical theory of games to biological contexts, having the advantages of truly reflecting the diversity and complexity to provide theoretical basis to study macro-control group behavior. The evolutionary game theory-based modeling and stability analysis of subsidy policy on safety investment in SMEs is studied, and the simulation about the effect of the alteration of the ratio on the evolvement results is executed. The results indicate that the safety subsidy of local governments can enhance SMEs' enthusiasm to invest. It has excellent significance to study further how to achieve equilibrium between SMEs and local governments using evolutionary game theory, and to provide theoretical basis to study operation mode of subsidy policy on safety investment in SMEs.
