【摘要】 基于中国2009—2022年285个地级市的面板数据，构建地方政府环境治理能力现代化水平指标体系，利用双向固定效应模型，多维度探究数字技术对地方政府环境治理现代化的影响效应及作用机制。研究发现，数字技术对提高地方政府环境治理能力现代化水平具有促进作用。数字技术可以通过开放数据要素、改善生产要素结构、升级知识和技能要素三个途径间接提升地方政府环境治理能力现代化水平。异质性分析表明，对于中心城市、非自然资源型城市和数字层级高的城市而言，数字技术对地方政府环境治理能力现代化水平的影响效果更好。进一步分析发现，专利保护对数字技术提升地方政府环境治理能力现代化水平起到正向调节作用；在精细化、智能化与数字化形成环境治理的新范式当下，地方政府对环境治理模式创新融合的关注度越高，当地数字技术对地方政府环境治理能力现代化水平的影响效应越强。更多还原

【Abstract】 Based on the panel data from 285 prefecture-level cities in China from 2009 to 2022,this paper constructs an indicator system for the modernization level of local government’s environmental governance capabilities and uses a double fixed effects model to explore the impact effect and mechanism of digital technology on the modernization of local government’s environmental governance from multiple dimensions. The study finds that digital technology promotes the modernization level of local government’s environmental governance capabilities. Digital technology can indirectly enhance the modernization level of local government’s environmental governance capabilities through three channels: opening data elements, improving the structure of production factors, and upgrading knowledge and skill elements. Heterogeneity analysis indicates that for central cities, non-natural resource-based cities, and cities with a high digital hierarchy, digital technology has a better impact on the modernization level of local government’s environmental governance capabilities. Further analysis reveals that patent protection plays a positive moderating role in enhancing the modernization level of local government’s environmental governance capabilities through digital technology; in the current new paradigm of environmental governance characterized by refinement, intelligence, and digitization, the higher the local government’s focus on the innovation and integration of environmental governance models, the stronger the impact effect of local digital technology on the modernization level of local government’s environmental governance capabilities.更多还原
