摘　　要：在新时代背景下,实现经济社会高质量发展的根本途径是城市发展效率提升,而数字经济在其过程中发挥着重要驱动作用.本文构建了数字经济驱动城市发展效率提升的理论分析框架,并采用时空双固定的空间杜宾模型实证检验了数字经济对城市发展效率的影响及空间溢出效应.研究发现:1)数字经济明显促进了本地区及周边地区的城市发展效率,并且该结论通过了一系列稳健性检验仍然成立;2)数字经济通过提高社会效益、经济效益和生态效益来促进城市发展效率提升,但提升作用受限于土地效益的减低,同时产业融合、技术进步以及城乡融合在其中发挥着重要的机制作用;3)数字经济驱动城市发展效率提升的作用呈现出“先降后升”的非线性变化趋势及空间溢出特点;4)数字经济对城市发展效率的影响存在城市等级和地理区域异质性,即在行政级别高和人口规模大的城市,以及东部和北方地区,数字经济驱动城市发展效率提升的作用更为明显.以上研究结论意味着,当前我国应以城市发展效率作为经济高质量发展的重要考量目标,并将数字经济发展作为驱动城市发展效率提升的主要动力.In the context of the new era,the fundamental way to promote high-quality economic and social development is to improve urban development efficiency,and digital economy plays an important driving role in the process.This paper constructs a theoretical analytical framework for digital economy-driven urban development efficiency improvement,and empirically tests the impact of digital economy on urban development efficiency and spatial spillover effects using a spatial and temporal double-fixed spatial Durbin model.This paper finds that:Firstly,digital economy significantly contributes to urban development efficiency in the region and surrounding areas,and the finding still holds through a series of robustness tests.Secondly,digital economy contributes to urban development efficiency by enhancing social,economic and ecological benefits,but the enhancement is limited by the reduction of land benefits,while industrial integration,technological advancement,and urban-rural integration play an important role in its mechanism.Thirdly,the effect of digital economy in driving the improvement of urban development efficiency shows a non-linear trend of“downward and then upward”and spatial spillover characteristics.Fourthly,there is city-level heterogeneity and geographic-area heterogeneity in the impact of the digital economy on urban development efficiency,which means that the role of digital economy in driving urban development efficiency is more pronounced in cities with high administrative levels and large populations,as well as in the eastern and northern regions.The above findings imply that at present,China should take urban development efficiency as an important target to consider for the high-quality economic development,and take the development of digital economy as the main driving force to improve urban development efficiency.
