　　摘要: Much concern has been raised over whether trade causes environmental damage in low-income developing countries. In this paper, we estimate the impact of trade liberalization on environmental performance using firm-level data. By adopting Brandt et al (2017)'s approach that uses the tariff rates from the accession agreement as instruments, we find that lowering input tariff leads to higher average SO2 emissions (9-11%) which is largely due to scale effects and composition effects while lowering output tariff has a weak negative effect on SO2 emissions. Given that we have unique and detailed firm-level information, we then trace through in detail the mechanisms through which trade liberalization contributes to technology upgrading. We find that the decrease of import tariff has a net negative effect on SO2 generation intensity which means the extent of free trade increase, the production becomes cleaner. We also find that compared to firms in non-treated cities, firms in cities with a more stringent environmental regulation increase less pollution intensity when the import tariffs decrease, which is consistent with the theory.
