Evolutionary Game Analysis of the Behavior Strategies of Participants in the Supply Chain Financial Credit Market under Government Subsidies

On the basis of clarifying participants in supply chain financial credit market and their behaviors, we use evolutionary game theory to construct a tripartite model for small medium-sized enterprises (SMEs), core institutions government subsidy environment, analyze equilibrium point. We also numerical simulation influence changes subsidies other factors different initial conditions on results. The results show that: 1) proportion active strategy selected by player has significant impact evolution system; 2) Government have great positive effect convergence system best stable state, but function itself is not universal. Therefore, needs rationally coordinate quotas participating entities accordance with actual situation, provide targeted support subsidies; 3) higher independent repayment rate SMEs, more converges state.
