环境规制垂直管理改革的减排效应——来自地级市环保系统改革的证据

Emission Reduction Effect of Vertical Management Reform in Environmental Regulation——Evidence from Environmental System Reform in Cities

本文研究了环境规制垂直管理改革对工业污染排放的影响及内在机制,研究发现:改革抑制了工业污染排放;其影响存在地区差异性,对中西部污染减排作用更为显著,还发现污染减排压力越大的地区影响越明显;改革对相对较低政治约束的城市的减排效应更为突出。研究还发现改革未提高地方政府的环境治理投入,但显著弱化了"地方规制偏向",提升了规制强度。进一步发现,垂直管理改革通过弱化"地方规制偏向"问题降低了工业污染排放水平。

We study the vertical reform of environmental regulation and its impact on industrial pollution discharge and mechanism. We find that the reform inhibits industrial pollution emissions with a more pronounced emission reduction effect for the lower political constraints, the greater pollution reduction pressure and in the central and western cities. We also find that the reform did not improve the environmental governance investment, while significantly weakened the local enforcement bias, and raised the regulatory strength. Finally, we find that the reform reduced the industrial pollution discharge via the channels of weakening the local enforcement bias.
