Abstract
Realizing the serious environmental problems caused by rapid industrialization, many developing countries have implemented pollution regulations in recent years. However, the socioeconomic effects of these policies have been relatively less studied. Using a natural experiment based on a national policy regulating sulfur dioxide (SO
2) emissions implemented in China since 1998, this study examines the policy’s effects on SO
2 emissions and industrial activities in Chinese municipalities. Employing a difference-in-differences approach, we compare the outcomes for municipalities classified as regulated zones (the treatment group) to municipalities not classified as regulated zones (the comparison group), before and after the policy took effect. We find that the policy reduced industrial SO...[

Realizing the serious environmental problems caused by rapid industrialization, many developing countries have implemented pollution regulations in recent years. However, the socioeconomic effects of these policies have been relatively less studied. Using a natural experiment based on a national policy regulating sulfur dioxide (SO
2) emissions implemented in China since 1998, this study examines the policy’s effects on SO
2 emissions and industrial activities in Chinese municipalities. Employing a difference-in-differences approach, we compare the outcomes for municipalities classified as regulated zones (the treatment group) to municipalities not classified as regulated zones (the comparison group), before and after the policy took effect. We find that the policy reduced industrial SO
2 emissions by about 20 percent, with the reduction mostly realized in the policy’s later stages. We also find that SO
2 emissions in a municipality increase if more of its neighbor municipalities are regulated, which suggests potential relocation of polluting firms from regulated areas to nearby unregulated places. While there are few significant effects on the industrial activities of domestic firms, we find that the policy negatively affected the activities (such as number of firms, total value produced, total assets and employment) of foreign firms in heavy-pollution industries.
