Abstract: This paper examines the impact of China's 1998 “Two Control Zones” (TCZ) policy on firm productivity and local economies using geolocated micro data. The analysis relies on an instrumental variable based on engineering considerations related to pollution emissions. We find that the TCZ policy led to the exit of low-productivity firms and reduced ten-year productivity growth among surviving firms. These surviving firms adjusted by reducing coal consumption, altering their product mix, and increasing innovation activities, resulting in significant transitional costs. The negative effects are disproportionately larger for initially high-productivity firms that engage more actively in abatement efforts. The adverse impact is amplified in counties with closely related industries and strong vertical linkages. These findings highlight the uneven distributional costs of place-based environmental regulations.
