摘　　要：数字经济是中国经济高质量发展的新动能,将为城市产业结构升级带来机遇。文章基于2004—2021年中国304个地级及以上城市样本数据,采用标准差椭圆模型、重心迁移模型等刻画了数字经济发展与城市产业结构升级的时空演变特征,并使用固定效应和空间计量模型对数字经济驱动城市产业结构升级的影响效应进行了实证研究。结果表明:①中国数字经济发展和城市产业结构升级成果显著,二者空间依赖与集聚特征鲜明,在环渤海、长三角、珠三角、成渝城市群等地区形成了高值空间集聚区。②数字经济驱动城市产业结构升级存在明显的区域异质性,对位于东部或长江经济带地区、经济发展水平更高、产业结构基础更优的城市而言,数字经济促进其产业结构升级的积极效应更显著。③数字经济不仅能促进本城市产业结构升级,还对周边城市产业结构升级产生较强的空间溢出效应。The digital economy is a new driving force for the high-quality development of China's economy,which will provide opportunities for the upgrading of urban industrial structure.Using standard deviation ellipse model,gravity center migration model and other methods,this paper examines the evolution characteristics of China's digital economy development and urban industrial structure upgrading based on the panel data of 304 cities at the prefecture-level and above in China from 2004 to 2021.It also applies the models of fixed effect and spatial econometrics to estimate the impact of digital economy on urban industrial structure upgrading.The findings indicate that:1)China has achieved remarkable progress in digital economy development and urban industrial structure upgrading,both of which exhibit strong spatial dependence and agglomeration patterns,forming high-value spatial agglomeration areas such as the Bohai Rim,Yangtze River Delta,Pearl River Delta,Chengdu-Chongqing urban agglomeration.2)There is significant regional variation in the impact of digital economy on urban industrial structure upgrading,the positive effect of digital economy in promoting the upgrading of their industrial structure is more significant in cities located in eastern region and the Yangtze River Economic Belt region and having higher levels of economic development and better industrial structure foundations.3)Digital economy not only enhances the industrial structure upgrading of the local city,but also generates substantial spatial spillover effects on the industrial structure upgrading of neighboring cities.
