摘要： 一个广泛共享的电动汽车电气化目标中的基本且未解答的问题是，电价（在不同国家和地区可能有很大差异）如何影响购买行为。 我在2021-2022年挪威发生南北价格差异较大的自然实验期间，利用这一情况来估计电价对购买纯电池电动车辆决策的影响。 沿价格区域边界的简单差异估计以及差异-in-差异回归模型表明，高电价区域购买电动汽车的概率减少了2-4%，这种影响显著但经济上较为温和。 一个反事实模拟表明，与南部地区电价与北部同样低的情况相比，高电价南部地区可能会少售出约3000到6000辆电动汽车。 显示英文摘要

摘要： A fundemantal and unanswered question for the widely shared goal of electrifying passenger vehicles is how the price of electricity, which can vary greatly across countries and regions, affects buying behavior. I make use of a natural experiment in Norway in the period 2021-2022 when large price differences between north and south emerged to estimate the effect of electricity prices on the decision to purchase a pure battery-electric vehicle. Simple difference estimates along the border of the price zones as well as a difference-in-difference regression model suggest a significant but economically modest effect of a 2-4\% reduction in the probability of purchasing an electric vehicle in the high price zone. A counterfactual simulation suggests that there would have been about 3000 to 6000 fewer electric vehicles sold in the high-price south compared to a scenario where the south had equally low prices as in the north.
