摘　　要：智慧城市作为城镇化和信息化发展到高级阶段的产物,是技术创新环境下城市发展的更高级形态,那么智慧城市是否能够推进绿色城镇化发展?本文基于2006—2020年中国276个地级市面板数据,构建多期DID模型实证分析国家智慧城市试点政策对绿色城镇化水平的影响和作用机制。结果表明,国家智慧城市试点政策能够显著提升绿色城镇化水平;国家智慧城市试点政策对绿色城镇化水平影响存在异质性,在东部地区、大规模城市和较高创新能力的试点城市中,国家智慧城市试点政策对绿色城镇化水平提升作用较为明显,但在其他试点城市中这种影响效应存在差异;国家智慧城市试点政策是通过提升城市环境基础设施运行效率和绿色全要素生产率提升绿色城镇化水平。本文为推进智慧城市的国家战略、践行绿色发展理念引领下的绿色城镇化道路以实现中国经济社会高质量发展提供了重要启示。As a product of urbanization and informatization to an advanced stage,a smart city requires exploring the model,system,technology,and industrial innovation of green and low-carbon development,promoting energy saving and emission reduction,reducing resource waste,and improving the ecological and livable environment,which is a more advanced form of urban development in the context of technological innovation.So,is smart city construction a panacea for promoting green urbanization?This paper constructs a multi-period DID model to analyze the impact of national smart city pilot policy on the level of green urbanization based on panel data of 276 prefecture-level cities in China from 2006 to 2020,and uses a mechanism test model to examine its path.It is found that firstly the national smart city pilot policy can significantly improve the level of green urbanization,and this finding still holds after robustness testing by the PSM-DID method and placebo test.Secondly,there is heterogeneity in the effect of national smart city pilot policy on the level of green urbanization.In the eastern region,large-scale cities,and pilot cities with strong innovation capacity,the effect of the policy on the level of green urbanization is more obvious,while in other pilot cities,this effect decreases with changes in regional location,city size,and innovation capacity.Thirdly,the national smart city pilot policy can indirectly affect the level of green urbanization through two paths:enhancing the operational efficiency of environmental infrastructure and improving green total factor productivity,both of which play a mechanism role.Compared with the previous literature,this study makes marginal contributions from two aspects.First,in terms of research perspective,taking the national smart city pilot policy as the entry point,it systematically explores the inner connection between smart city construction and green urbanization,expanding the theoretical study of green urbanization under the new development philosophy.Second,in terms of res
