补贴政策下考虑充电设施建设水平的充电定价与策略研究

Research on charging pricing and strategy considering the construction level of charging infrastructure under subsidy policy

摘要:

针对不同补贴政策下运营商的决策与不同充电设施建设水平下政策实施的策略问题，文章构建基准模式、投资补贴模式、运营补贴模式和复合补贴模式等四种政策情境，分析比较不同政策情境下运营商定价及补贴策略，结果表明：①充电价格随着运营补贴的强度提升而下降，电动汽车的市场渗透率提升，充电运营商收益增加；②政策性因素、市场性因素、成本性因素和时间性因素对价格、需求和收益具有直接和交叉影响。③当充电设施建设水平小于0.5时，运营补贴更能刺激新能源汽车的扩散。当充电设施建设水平大于0.5时，可适时退出补贴政策。

Abstract:

To solve this problem which is the differences in the operator’s decision-making under different subsidy policies, and the strategy of policy considering different construction levels of charging infrastructure, this article builds four policy scenarios: basic model, investment subsidy model, operating subsidy model, and compound subsidy model. This article analyzes and compares operators' pricing and subsidy strategies under different policy scenarios. The research results show that: ① The charging price decreases with the increase in the intensity of operating subsidies, the market penetration rate of electric vehicles increases, and the income of charging operators increases. ②Policy factors, market factors, cost factors, and time factors have direct and cross-effects on prices, demand, and income.③When the construction level of charging infrastructure are less than 0.5, the implementation of the strategy of operating subsidies will result in better policy effects. When the construction level of charging infrastructure is greater than 0.5, the subsidy policy can be withdrawn in due course.
