市场一体化对中国环境质量的影响研究

Research on the Impact of Market Integration on China's Environmental Quality

本文基于2004~2019年中国30个省际面板数据,运用空间杜宾模型从国内贸易、产业转型和强化环境规制的角度实证考察了市场一体化的环境效应。结果表明:市场一体化的提高显著改善了本区域环境质量,并在一定程度上抵消了邻近地区的环境恶化效应。从机制检验来看,市场一体化的提升使省际间贸易由隐含污染转移向显性污染转移过渡,使本地环境质量改善而邻近地区趋于恶化;市场一体化通过污染产业转移和产业结构优化改善了本地环境质量,对邻地影响不显著;市场一体化的推进显著强化了环境规制,加强了省际间联合治理环境的合作关系,优化了“本地—邻地”环境质量。

Based on the panel data of 30 provinces in China from 2004 to 2019,this paper empirically examines the environ⁃mental effects of market integration from the perspectives of domestic trade,industrial transformation and strengthening environmen⁃tal regulation.The results show that the improvement of market integration has significantly improved the environmental quality in this region,and to some extent offset the environmental deterioration effect in neighboring areas.From the mechanism test,the pro⁃motion of market integration makes the inter-provincial trade transition from implicit pollution to explicit pollution,which improves the local environmental quality and worsens the neighboring areas;market integration improves the local environmental quality through the transfer of polluting industries and optimization of industrial structure,and has no significant impact on neighboring areas;the promotion of market integration has significantly strengthened environmental regulation and inter-provincial cooperation in joint environmental governance,which optimized“local-neighboring”environmental quality.
