Mandatory pollution abatement and firm export product quality

Abstract

This study investigates the effect of mandatory pollution abatement on the export product quality of firms. Using the chemical oxygen demand reduction targets specified in the 11th Five-year Plan of China as an exogenous shock, we document that firms under stringent environmental regulation experience an upgrading in their export product quality, and our findings remain robust under a battery of tests. Plausible mechanisms are reduced wastewater emissions, the adoption of sewage treatment facilities, and promoted innovation. We show that the effect is highly pronounced in non-state-owned enterprises and firms located in downstream cities. Our findings provide policy implications on unintended consequences of environmental regulation on local firms’ product quality.
