摘 要：Measuring environmental regulation’s effect on firm competitiveness is central to designing optimal policies. Existing studies document significant negative effects of air pollution regulations on manufacturing competitiveness as measured by total factor productivity (TFP). A separate literature finds that air pollution lowers TFP through its ambient effect on workers’ physical and mental health and cognition. Extant empirical measures reflect some combination of the competitiveness and ambient effects and only under specific circumstances will they reflect the average policy effect across all firms. We develop a boundary-discontinuity-difference-in-differences approach to isolate the competitiveness effect: both regulated and unregulated firms adjacent to each other enjoy the ambient effect via spillovers but only regulated firms suffer the competitiveness effect. We apply the approach to a major air pollution regulation in China. The traditional approach to estimating the regulation’s effect yields a 3.75% TFP decline and net policy cost of USD 21.2 billion. The true competitiveness effect is 6.40% implying an ambient effect of 2.65% among regulated firms. The true cost of the policy is lower (about USD 10.4 billion) because proximate non-regulated firms also enjoy the ambient effect.
