臭氧（O-3）污染构成健康风险和过早死亡，而加油站是城市挥发性有机化合物（VOCs， O-3的主要前体）的最大来源之一。政府呼吁夜间加油，这可以被视为一种绿色推动，是否可以引导消费者行为的变化，从而改善环境质量，本文对此进行了研究。利用差分法和每周监测站点空气质量面板数据，分析了夜间加油优惠政策对O-3浓度的影响。我们发现，通过鼓励消费者在夜间加油，该政策可以将O-3浓度降低10%。O-3的减少给人类健康带来了巨大的好处，使江苏省的非意外死亡率降低了4-5%，心血管死亡率降低了6-8%。如果在全国范围内实施，该政策的经济效益约为620 - 1890亿元人民币。本研究结果提示政府可以通过影响消费者行为来促进环境质量。
Ozone (O-3) pollution poses health risks and premature mortality, and gas stations are one of the largest sources of urban volatile organic compounds (VOCs, the main precursor to O-3). This paper investigates whether the government's call for night refueling, which can be regarded as a green nudge, can guide changes in consumer behavior and consequently improve environmental quality. Using a difference-in-differences (DID) estimation and weekly monitoring site air quality panel data, we analyze the effect of the Night Refueling Preferential Policy on O-3 concentrations. We find that the policy can reduce O-3 concentrations by 10% by encouraging consumers to refuel at night. The reduction in O-3 has brought great benefits to human health, leading to a 4-5%o reduction in non-accidental mortality and a 6-8%o reduction in cardiovascular mortality in Jiangsu province. The economic benefits of this policy would be approximately 62-189 billion Chinese Yuan (CNY) if it were implemented nationwide. The findings of this study suggest that the government can influence consumer behavior to promote environmental quality.
