Abstract
This study provides evidence that trade expansion has contributed to the degradationof air pollution in China. On the basis of different responses of counties’ trade toChina’s World Trade Organization accession at the end of 2001, we exploit airpollution data from NASA to construct a difference-in-differences predicted trade asan instrument for our identification. We document statistically significant and robustevidence on trade expansion, which accounts for approximately 60% and 20% for theincrease of PM2.5 and SO2, respectively, in China. Findings on trade pollution relationare robust to various tests. Deterioration in the environment is mainly driven by scaleand trade in polluting sectors.
Key words: trade openness; air pollution; instrument variable; China
