Global climate change has caused a series of environmental problems, green technology innovation is necessitating strategic responses, but the impact of low-carbon city pilot policy on urban green technology innovation is unclear. Based on panel data from 285 Chinese cities during 2005-2022, this study employs the Difference in Difference method to examine the impact of low-carbon city policy on urban green technology innovation. The results show that (1) The low-carbon city pilot policy promotes urban green technology innovation. (2) The low-carbon city pilot policy promotes urban green technology innovation through government green input and public engagement. (3) New infrastructure enhances the impact of low-carbon city pilot policy on quantity of green technology innovation. (4) Compared with the Yangtze River Economic Belt, the low-carbon city policy has a greater influence on urban green technology innovation in the Yellow River Basin.The findings provide policy insights for the construction of low-carbon pilot cities.
全球气候变化引发了一系列环境问题，绿色技术创新需要战略响应，但低碳城市试点政策对城市绿色技术创新的影响尚不清楚。本研究基于 2005-2022 年中国 285 个城市的面板数据，采用双重差分法考察了低碳城市政策对城市绿色技术创新的影响。结果表明：（1）低碳城市试点政策促进了城市绿色技术创新；（2）低碳城市试点政策通过政府绿色投入和公众参与促进了城市绿色技术创新；（3）新基础设施增强了低碳城市试点政策对绿色技术创新数量的影响；（4）与长江经济带相比，低碳城市政策对黄河流域城市绿色技术创新的影响更大。研究结果为低碳试点城市建设提供了政策启示。
