| 摘 要： 将智慧城市试点的设立视为一项准自然实验，使用2005—2018年地级市经济数据，利用双重差分方法实证分析了智慧城市建设对地区绿色全要素生产率的影响。研究发现：第一，智慧城市建设对地区绿色全要素生产率提高有显著的促进作用；第二，智慧城市建设对环境效率与能源效率均存在正向影响；第三，智慧城市建设提高绿色全要素生产率的效应在东部城市比在其他地区城市更强，在大城市比在小城市更强；第四，智慧城市建设可以通过提高地区科技创新能力、环境规制程度与产业结构服务化水平促进绿色全要素生产率提升。 |

| Abstract: By considering the establishment of the smart city pilot as a quasi-natural experiment, and by using prefecture-level city economic data of the years 2005-2018, and using DID method, the present study analyzes the impact of smart city construction on urban green total factor productivity. The study finds that, firstly, the construction of smart cities has significantly improved the green total factor productivity of cities; secondly, the construction of smart cities can improve environmental efficiency and energy efficiency; thirdly, the effect of smart city construction on improving green total factor productivity is stronger in eastern cities than in other regions, and stronger in large cities than in small cities; and fourthly, the construction of smart cities can promote the green total factor productivity by improving the city's scientific and technological innovation capabilities, increasing degree of environmental regulation, and improving the service-oriented industrial structure. |
