摘要
2019年下半年以来,由于政府补贴大幅降低,充电设施不足等问题,导致国内新能源汽车销量增速放缓。为解决这一问题,换电模式开始受到关注,但换电站前期建设成本太高使得换电模式发展困难。因此考虑引入PPP模式,即政府引导新能源汽车企业与电池企业合作进行换电站的建设和运营。为了分析在这个模式下各群体的合作意愿,本文建立了一个三方演化博弈模型,计算和分析了在不同情形下的演化稳定策略,得出各群体都倾向于合作的情形是存在的,并讨论了几个影响合作行为的关键因素。结果表明:政府补贴、换电成本、当前模式的利润、电价、充电时长和换电风险会影响演化稳定策略向三方合作演化。
Since the second half of 2019, the growth of domestic new energy vehicles sales has slowed down due to the decrease of government subsidies and insufficient charging facilities. In order to solve this problem, the power exchange mode began to be concerned, but the high construction cost of the power exchange station makes the development of the power exchange mode difficult. Therefore, it is necessary to introduce the PPP model, that is, the government guides the new energy vehicle enterprises to cooperate with battery enterprises to build and operate the power station. In order to analyze the willingness of each group to cooperate in this model, this paper establishes a tripartite evolutionary game model, calculates and analyzes the evolutionary stability strategies in different situations, and concludes that the situation that each group tends to cooperate exists, and discusses several key factors affecting the cooperative behavior. The results show that government subsidies, cost of electricity exchange, profit of current mode, electricity price, charging time and risk of electricity exchange will affect the evolution of evolutionary stability strategy to tripartite cooperation.
