Green and sustainable development is unstoppable. The digital economy has driven great changes in production methods and has become a key strength in reshaping global economic structure and achieving sustainable development. Cities are both the mainstay of economic growth and the main source of various environmental pollution problems. Therefore, studying the relationship between urban digital economy and urban green total factor productivity is of great significance. Based on panel data from 252 cities in China 2011-2019, a two-way fixed effects model was used to examine the impact of urban digital economy on urban green total factor productivity. The empirical results indicate that: (1) Urban digital economy has a significant positive impact on urban green total factor productivity. (2) Urban technological-innovation-level and human-capital-structure of play a mediating role in the impact. (3) This impact has regional heterogeneity and resource-based type heterogeneity. The research conclusions are not only valuable supplements to previous research, but also providing reliable instructions for implementing a flexible digital economy policy.
绿色与可持续发展势不可挡。数字经济推动了生产方式的巨大变革，已成为重塑全球经济结构和实现可持续发展的关键力量。城市既是经济增长的支柱，也是各种环境污染问题的主要源头。因此，研究城市数字经济与城市绿色全要素生产率之间的关系具有重要意义。基于2011 - 2019年中国252个城市的面板数据，采用双向固定效应模型考察城市数字经济对城市绿色全要素生产率的影响。实证结果表明：（1）城市数字经济对城市绿色全要素生产率有显著的正向影响。（2）城市技术创新水平和人力资本结构在该影响中起中介作用。（3）这种影响具有区域异质性和资源型异质性。研究结论不仅是对以往研究的有价值补充，也为实施灵活的数字经济政策提供了可靠指导。
