Over the past decade, straw burning has been debated as one of the causes of severe air pollution in developing countries. However, the magnitude and pattern of its impact on air quality have not been precisely estimated. This paper employs satellite remote sensing data on straw burning and examines the overall impact of straw burning on air quality in China for the first time. Based on the difference-in-differences analysis of the panel data from 290 cities and 620 days, I find that on the first day after straw burning the index of air pollution increases by 7.3 in urban areas, equivalent to 11% of average level. This pollution effect is significant for up to 11 days and 600 kilometers. Moreover, the effects are heterogeneous in relation to different air pollutants, seasons, and levels of pollution. Straw burning increases PM2.5 of the next day by 5.3 μg/m3 and PM10 by 10.3 μg/m3. While the resulting pollution is significant in all seasons, it is strongest in October and November when straw is burned in the north after harvest. In the context of high initial air pollution levels, straw burning’s pollution effect is larger and lasts longer. The results are robust in more flexible models.
