Data and Code for: Changing population exposure to pollution in China’s Special Economic Zones

We document that widespread migration into China's industrial clusters between 2000-2010 did little to change overall population exposure to pollution. Using satellite air pollution data, we show that there is much heterogeneity across zones and that most population growth occurred in relatively cleaner zones, supporting recent literature that documents local willingness to make location decisions based on environmental quality.

本研究证实，2000年至2010年间大规模流入中国产业集群的移民，并未显著改变整体人口所面临的污染暴露水平。本研究借助卫星遥感空气污染数据，揭示出不同区域的污染暴露程度存在显著异质性，且绝大多数人口增长均发生在环境相对清洁的区域，这一发现为近期相关研究文献提供了实证支撑——此类文献表明，居民在进行居住区位决策时，会将环境质量作为重要的考量依据。
