为缓慢的充电市场提供动力：政府补贴如何影响充电站供应？
Powering Up a Slow Charging Market: How Do Government Subsidies Affect Charging Station Supply?
摘要：
电动汽车的采用被认为是应对气候变化的一个有前途的途径。然而，充电站市场存在市场失灵：缺乏电动汽车销售抑制了充电站的生产，这反过来又抑制了电动汽车的大规模采用。充电站补贴经常被讨论为政策杠杆，可以刺激充电站供应并纠正这种市场失灵。尽管如此，研究此类补贴在促进充电站供应方面的成功程度的研究有限。使用加州57个县的电动汽车销售，充电站数量和补贴金额的年度数据以及交错差异方法，我发现充电站补贴非常有效：采用补贴的县在采用补贴后2年内充电站供应增加了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失灵。
英文摘要：
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.
