本文利用挪威2021-2022年南北电力价格差异的自然实验，通过双重差分模型发现高价区电动汽车购买概率降低2-4%，反事实模拟显示高价南方少售约3000-6000辆。
摘要：
对于广泛共享的乘用车电动化目标而言，一个根本且尚未解答的问题是，各国和各地区差异巨大的电力价格如何影响购买行为。我利用了挪威2021-2022年期间出现南北巨大价格差异的自然实验，来估计电力价格对购买纯电池电动汽车决策的影响。沿价格区边界的简单差分估计和双重差分回归模型表明，在高价区购买电动汽车的概率降低了2-4%，这一效应显著但在经济上较为温和。反事实模拟表明，与南方拥有与北方同样低价格的情景相比，高价南方售出的电动汽车将减少约3000至6000辆。
英文摘要：
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.
