The reform of environmental management systems is key to improving environmental pollution treatment and green technology innovation. Based on panel data on 30 provincial administrative regions in China for 2008 to 2016, this paper analyzes the impacts of environmental decentralization and environmental protection investment on green technology innovation. It is first found that environmental decentralization promotes green technology innovation after inhibition. Similar effects are found for environmental administrative decentralization, environmental monitoring decentralization, and environmental supervision decentralization. Second, in the long run, environmental decentralization in developed and low-emission regions is more conducive to green technology innovation. Third, environmental pollution treatment investment has a significant inhibiting effect on green technology innovation under high levels of environmental decentralization, and the inhibiting effects of industrial pollution source treatment investment and "three simultaneous" construction project investments are particularly obvious. This paper explores green technology innovation as the goal of environmental decentralization, which is the driving force behind pollution control. From the perspective of environmental protection investment, the paper further analyzes the impact of environmental decentralization on green technology innovation. The study has important reference value for determining reasonable levels of environmental decentralization among different levels of governance and in formulating differentiated strategies of environmental decentralization.
环境管理体制改革是提升环境污染治理与绿色技术创新水平的关键。本文基于 2008-2016 年中国 30 个省级行政区的面板数据，分析了环境分权和环境保护投资对绿色技术创新的影响。研究结果表明，环境分权对绿色技术创新具有先抑制后促进的倒“U”型影响，其中环境行政分权、环境监测分权和环境监管分权均表现出相似的影响。其次，在长期内，发达和低排放地区的环境分权更有利于绿色技术创新。再次，在环境分权水平较高的情况下，环境污染治理投资对绿色技术创新具有显著的抑制作用，其中工业污染源治理投资和“三同时”建设项目投资的抑制作用尤为明显。本文以绿色技术创新为环境分权的目标，探索了污染治理的内在动力。从环境保护投资的角度，进一步分析了环境分权对绿色技术创新的影响。本研究对于确定不同治理层次的环境分权合理水平以及制定差异化的环境分权策略具有重要的参考价值。
