地方政府环境治理目标约束强度与绿色经济效率

Constraint Intensity of Environmental Governance Objectives of Local Governments and Green Economic Efficiency

本文收集整理了2010—2017年中国275个地级市政府年度工作报告,利用文本挖掘法构建了地方政府环境治理目标约束强度指标,并利用加权SBM-DEA模型测度了地区绿色经济效率。基于上述指标的实证研究发现:地方政府环境治理目标约束有“硬约束”和“软约束”之分,硬约束环境治理目标能更有效推动地方绿色经济效率的提升;污染挤出效应和产业升级效应是硬约束环境治理目标改善地方绿色经济效率的重要机制;市场化水平对地方政府环境治理目标约束作用存在调节效应,市场机制与地方政府环境治理目标协同更有助于实现区域绿色发展。

This paper collects and processes the annual work reports of 275 prefecture level municipal governments in China from 2010 to 2017,constructs the constraint intensity index of local government environmental governance objectives using text mining methods,and measures the regional green economy efficiency using the weighted SBM-DEA model.The empirical study based on the above indicators shows that the constraints of local government environmental governance objectives can be divided into“hard constraint”and“soft constraint”.Local governments can promote the local green economy efficiency more effectively by setting hard constraint environmental governance objectives.Pollutioncrowding out effect and industrial upgrading are important mechanisms to improve the efficiency of local green economy.The level of marketization has a moderate effect on the constraints of local government environmental governance objectives.The synergy between market mechanism and local government environmental governance objectives is more conducive to regional green development.
