Accurately assessing the impact of low-carbon urban construction on green economic development has great significance for achieving economic development with environmental protection, and for building an ecological civilization and a beautiful China. Based on panel data for 271 cities in China from 2004 to 2019, multi-period and spatial difference-in-difference econometric models were used to comprehensively investigate the impact of three batches of low-carbon city pilot policies on green economic development, finding the following: The contribution of low-carbon urban construction on urban green economic development is significant and positive, and still holds under a series of robustness tests. Parallel trend tests also show a lag in the policy effect, and the effect is strengthened over policy implementation time. Green orientation of technological progress, green transformation of industry, and green upgrade of consumption are important channels for the effect of the policies. The promotion effect of low-carbon city construction is stronger in the central and northern cities, and in cities with high green economic development, than in western and southern cities, and those with low green economic development. Construction of low-carbon pilot cities not only promotes their own green economic development, but also that in neighboring cities, exerting a demonstration effect. This effect is greater in urban areas. This study provides empirical support for policy planning to promote low-carbon urban construction across the country.
准确评估低碳城市建设对绿色经济发展的影响，对于实现环境保护与经济发展协同共进、建设生态文明和美丽中国具有重要意义。基于2004年至2019年中国271个城市的面板数据，运用多期和空间双重差分计量模型，全面考察三批低碳城市试点政策对绿色经济发展的影响，研究发现：低碳城市建设对城市绿色经济发展的贡献显著且为正向，在一系列稳健性检验下依然成立。平行趋势检验还表明政策效应存在滞后性，且随着政策实施时间的推移效应增强。技术进步的绿色导向、产业的绿色转型和消费的绿色升级是政策效应发挥作用的重要渠道。低碳城市建设在中部和北部城市以及绿色经济发展水平较高的城市中的促进作用，强于西部和南部城市以及绿色经济发展水平较低的城市。低碳试点城市建设不仅促进了自身的绿色经济发展，还带动了周边城市的绿色经济发展，发挥了示范效应。这种效应在城市地区更为明显。本研究为全国推进低碳城市建设的政策规划提供了实证支持。
