摘　　要：为准确评估试点城市建设的绿色发展效应及不同试点政策之间的协同作用,将低碳城市和创新型城市双试点作为研究对象,基于2007—2020年中国282个城市的面板数据,使用多期DID模型实证检验双试点城市建设对绿色全要素生产率的影响效果及其作用机制。实证结果表明,相较于非双试点城市,双试点政策能显著促进城市绿色全要素生产率的增长,并且,相较于单试点政策,低碳城市和创新型双试点城市建设对地区经济绿色发展的推动作用更为明显。进一步研究发现,双试点城市可以通过提升城市绿色技术创新水平与优化产业结构两条途径促进绿色全要素生产率的增长。异质性分析表明,双试点城市建设对东部城市和非资源型城市绿色全要素生产率的促进作用更为明显。In order to accurately assess the green development effect of pilot city construction and the synergy between different pilot policies,the dual-pilot of low-carbon cities and innovative cities is taken as the research object,and the effect of the dual-pilot city construction on green total factor productivity and its mechanism of action are empirically examined based on the panel data of 282 cities in China from 2007 to 2020 using a multi-period DID model.The empirical results show that compared with non-dual pilot cities,the dual pilot policy can significantly promote the growth of green total factor productivity in cities;compared with the single pilot policy,the construction of lowcarbon cities and innovative dual pilot cities has a more significant effect on the green development of regional economies.Further study finds that the dual pilot cities can promote green total factor productivity growth through two ways:improving the level of green technology innovation and optimizing industrial structure.The heterogeneity analysis shows that the dual pilot city construction has a more obvious role in promoting green total factor productivity in eastern cities and non-resource-based cities.
