Abstract: This paper aims to explore how regional environmental regulations affect firms' choice of pollution abatement technologies. Using a novel city-level dataset on environmental regulatory stringency and a dataset on firm-level pollution in China, we investigate the effect of environmental regulations on firm responses, represented by the choice between production process control and end-of-pipe treatments. The estimation results from the difference-in-difference-in-differences analysis show that stricter environmental regulations induce production process control and end-of-pipe treatments in firms. More importantly, we find a substitutionary relationship between production process control and end-of-pipe treatments. The heterogeneity analysis suggests that small firms, firms with a low pollution abatement capacity, and firms in cities with special policy zones tend to choose production process control. In contrast, large firms and those with a high pollution abatement capacity prefer to choose end-of-pipe treatments.
