An Evolutionary Game Analysis of Stakeholders'Behavior in Charging Infrastructure Based on System Dynamics
Charging infrastructure development imbalance between supply and demand is rising in China.Based on the perspective of stakeholders,the multi-agent evolutionary game model of charging in-frastructure is established,and numerical simulation for system dynamics is carried out to study the evolu-tionary stability strategy of the government,the operators and consumers,and the parameter variable's influence on the strategy of subject choice.The simulation results show that the active operation of opera-tors is the prerequisite for consumers to buy electric cars and the key to the stable state of the whole sys-tem lies in the operator's choice of strategy;the key factors to promote the evolution of the system to a stable equilibrium state are the intensity of construction operation subsidies,the cost of government super-vision and the severity of punishment to operators.Based on the simulation results and from the perspec-tive of supply side,this paper proposes that the government should formulate a reasonable subsidy system for infrastructure construction and operation,improve the supervision mechanism,establish an effective punishment mechanism,and slow down the regression speed of subsidies;operators should seek long-term cooperation with power grid companies to broaden profit channels and innovate business models.The re-search results can contribute to the rapid development of China's charging infrastructure.
