Does Environmental Regulation Matter for Income Inequality? New Evidence from Chinese Communities
利用中国健康与营养调查数据，研究发现旨在减少二氧化硫排放的环境规制使收入不平等降低了14%–27%，主要通过压低高收入群体工资、同时保持低收入群体（尤其是蓝领工人）工资不变来实现。
This study uses data from an ongoing, open-cohort, longitudinal China Health and Nutrition Survey to examine how the environmental regulation aimed at abating sulfur dioxide (SO2) alters income distribution. We find that this regulation induces a 14%–27% decrease in income inequality, depending on the measurement method. An improvement in income inequality is achieved by lowering the wages of high-income groups while keeping the wages of low-income groups (especially blue-collar workers) unchanged. This change in the labor market can be attributed to a policy that primarily targets emissions from power plants while leaving the manufacturing sector unaffected. As a result, the manufacturing sector continues to create jobs and absorb the blue-collar workers dismissed from other sectors, mitigating the widening income gap. Our study sheds new light on the role of environmental policy in reshaping the labor market and its implications for income distribution.
