中文摘要:

      本研究利用“撤县设区”和“省直管县”改革来刻画行政权力向市级政府的集中和分散，构建双重差分模型，基于地级市面板数据，检验了行政权力调整对城市绿色全要素生产率的影响。研究结果表明，行政权力集中加强了市级政府的资源统筹调配能力，通过提高技术创新水平、增加环保支出规模、降低工业产值比重等渠道，显著提升了城市绿色全要素生产率。而行政权力分散的影响效应相反，并不利于城市绿色高质量发展。相较而言，行政权力集中的正效应在政府行为规范度较高、市辖区经济较强的城市表现更突出，行政权力分散的负效应在政府行为规范度较低、县区经济相对较强的城市有着充分体现。对于高行政级别的城市，行政权力调整的影响并不显著。据此，从优化各级政府职能体系，分阶段、分类型，渐进式推进行政管理体制改革等方面提出对策建议。

英文摘要:

      Using the reform of "city-county merger" and "province-managing-county" to characterize the centralization and decentralization of administrative power to municipal governments, the difference-in-differences (DID) model is constructed to test the impact of administrative power adjustment on urban green total factor productivity (GTFP) based on panel data of prefecture-level cities. The results show that the centralization of administrative power strengthens the ability of municipal governments to coordinate resources, which significantly improves urban GTFP through the channels of improving technological innovation, increasing the scale of environmental protection expenditures and reducing the proportion of industrial output. The opposite effect of decentralized administrative power is negative for cities' green high-quality development. In contrast, the positive effect of centralized administrative power is more outstanding in cities with high governmental behavior and strong municipal economy, while the negative effect of decentralized administrative power is fully reflected in cities with low governmental behavior and relatively strong county economy. For cities with high administrative levels, administrative power adjustment's effect is insignificant. Accordingly, countermeasures are proposed to optimize the system of government functions at all levels and gradually advance the administrative management system's reform by stages and types.
