论文摘要
采用电动汽车被认为是解决气候变化的有前途的途径。但是，充电站的市场遭受了市场故障的损失：缺乏电动汽车销售障碍，从而使电台的产量充电，这反过来抑制了质量电动汽车的采用。通常将充电站补贴作为政策杠杆讨论，可以激发充电站的供应并纠正该市场故障。但是，研究有限的研究研究了此类补贴在促进充电站供应方面成功的程度。使用有关电动汽车销售，充电站数量以及来自57个加利福尼亚县的补贴金额以及交错差异差异方法的年度数据，我发现收费站的补贴是非常有效的：采用补贴的县在补贴采用后两年的充电站供应量增加了36％。这一发现表明，政府干预可以帮助纠正充电站市场的市场故障。
Electric vehicle adoption is considered to be a promising pathway for addressing climate change. However, the market for charging stations suffers from a market failure: a lack of EV sales disincentives charging station production, which in turn inhibits mass EV adoption. Charging station subsidies are often discussed as policy levers that can stimulate charging station supply and correct this market failure. Nonetheless, there is limited research examining the extent such subsidies are successful in promoting charging station supply. Using annual data on electric vehicle sales, charging station counts, and subsidy amounts from 57 California counties and a staggered difference-in-differences methodology, I find that charging station subsidies are highly effective: counties that adopt subsidies experience a 36% increase in charging station supply 2 years following subsidy adoption. This finding suggests that governmental intervention can help correct the market failure in the charging station market.
