Municipal solid waste (MSW) sorting not only reduces the total quantity of domestic waste but also has positive effects on urban air quality. In this study, using a careful identification strategy and air quality data at the monitoring station level in Shanghai, we estimate the causal effect of the MSW sorting policy on urban air quality. The results show that after the MSW sorting policy was implemented, the air quality index (AQI), nitrogen dioxide (NO2) and carbon monoxide (CO) decreased significantly by 2.71%, 2.07% and 3.62%, respectively. We also find a positive spillover effect from the Shanghai MSW sorting policy on the air quality of adjacent cities. The implementation of this policy has triggered changes in residents' behaviors. However, the government needs further efforts to maintain the sustainability of MSW sorting policies.
城市生活垃圾（MSW）分类不仅可以减少生活垃圾的总量，而且对城市空气质量有积极影响。在这项研究中，我们使用了一种仔细的识别策略和上海市监测站水平的空气质量数据，来估计 MSW 分类政策对城市空气质量的因果效应。结果表明，MSW 分类政策实施后，空气质量指数（AQI）、二氧化氮（NO2）和一氧化碳（CO）分别显著下降了 2.71%、2.07%和 3.62%。我们还发现，上海 MSW 分类政策对相邻城市的空气质量具有正向溢出效应。该政策的实施引发了居民行为的变化。然而，政府需要进一步努力，以保持 MSW 分类政策的可持续性。
