摘　　要：低碳城市试点是我国实施绿色发展战略的重要抓手。为了检验低碳城市试点方案(Low Carbon City Pilot Scheme,LCCPS)对我国城市绿色技术创新水平的直接影响和间接影响,更全面地理解该政策的影响范围和效果,基于2003-2020年中国城市绿色专利授权数据构建了空间双重差分模型(Spatial Difference-in-Difference,SDID)。结果表明:①低碳城市试点政策能够显著促进本地城市绿色技术创新,却对邻近城市绿色技术创新具有抑制作用。②相对于中部、西部、东北地区,低碳城市试点政策对我国东部地区的绿色技术创新水平的影响最大。③低碳城市试点政策对城市规模大的地区的绿色创新技术水平有更强的促进作用,同时城市规模大的城市对邻近地区绿色技术创新有着明显的促进作用。与资源型城市相比,非资源型城市通过实施低碳城市试点政策可以更好地推动绿色创新技术的研发,且资源型城市对其邻近地区绿色技术创新有显著的抑制作用。④机理分析表明,科技人才、绿色财政支持、绿色投资是低碳城市试点政策影响城市绿色技术创新的机制路径。Low carbon city pilot is an important part of China's implementation of low carbon,green development strategy.In order to test the direct and indirect impacts of Low Carbon City Pilot Scheme(LCCPS)on the level of urban green technology innovation in China and gain a fuller understanding of the policy's reach and impact,this paper constructs a Spatial Difference-in-Difference model based on the data of urban green patent authorization in China from 2003 to 2020.It is found that:①Pilot policy for low-carbon cities can significantly promote local urban green technology innovation,but had an inhibitory effect on green technology innovation in neighboring cities.②Compared to the central,western,and northeastern regions,the impact of pilot policy for low-carbon cities on the level of green technology innovation in the eastern region of China was the most significant.③Pilot policy for low-carbon cities had a stronger promoting effect on the level of green innovation technology in regions with large urban scales,while large cities had a clear promoting effect on green technology innovation in neighboring areas.Compared with resource-based cities,non-resource-based cities can better promote the R&D of green innovation technology through the implementation of pilot policy for low-carbon cities,while resource-based cities have a significant inhibitory effect on green technology innovation in their neighboring areas.④Mechanism analysis shows that talent,green financial support,and green investment are the mechanisms and pathways through which pilot policies for low-carbon cities affect urban green technology innovation.From a spatial perspective,this study on low-carbon pilot policies is of great significance for deepening the understanding of policy effects,revealing regional interaction mechanisms,promoting regional coordinated development,guiding policy formulation and implementation,as well as promoting green development and addressing climate change.
