为实现碳中和，在更清洁的电网中推广电动汽车已成为全球城市的关键路径。尽管大量研究已考察了电动汽车（EV）的环境效益，但其财务影响仍未得到充分探索。我们以新加坡——一个智慧城市国家——作为社会实验室，将电动汽车充电桩地理分布的高分辨率数据与来自一家大型商业银行的近100万条个人月度支出记录以及约65,000条住房交易记录相结合，时间跨度从2019年1月至2021年3月。结果表明，在电动汽车基础设施部署的初期阶段，靠近充电站显著使家庭消费增加1%至3%。这一效应主要由公共住房居民驱动，他们通常比私人住房居民面临更大的财务约束。我们识别出支撑这一消费增长的三个渠道：住房财富增值、围绕电动汽车基础设施的商业活动和可自由支配支出的催化剂作用，以及从燃油支出向其他消费类别的预算重新分配。值得注意的是，混合动力汽车车主表现出最强的权衡效应——在公共住房居民中，减少燃油支出的同时增加了娱乐或必需品的支出。总体而言，我们的研究结果表明，绿色基础设施能够塑造经济行为并提升消费者福利，其影响超越了环境目标本身。
英文摘要
To achieve carbon neutrality, electrifying vehicles in a cleaner electricity grid has become a key pathway for global cities. While extensive research has examined the environmental benefits of electric vehicles (EVs), their financial impacts remain underexplored. Using Singapore-a smart city-state - as a social laboratory, we combine high-resolution data on the geographic distribution of EV chargers with nearly 1 million individual-level monthly expenditure records from a major commercial bank and about 65,000 housing transaction records, spanning January 2019 to March 2021. Our results show that proximity to charging stations during the initial phase of EV infrastructure rollout significantly increases household consumption by 1-3%. This effect is driven primarily by public housing residents, who are generally more financially constrained than their private housing counterparts. We identify three channels underlying this increase in consumption: appreciation in housing wealth, catalysts for commercial activity and discretionary spending around EV infrastructure, and budget reallocation from fuel expenses to other consumption categories. Notably, hybrid car owners exhibit the strongest trade-offs-reducing fuel spending while increasing expenditure on entertainment or necessity goods among public housing residents. Overall, our findings demonstrate that green infrastructure can shape economic behavior and enhance consumer welfare, extending its impact beyond environmental objectives.
