摘要

基于生态位视角，综合运用生态学、计量经济学和空间统计学方法，以长江经济带为研究对象，通过测度2011—2022年各城市综合竞争力水平，探究数字经济提升城市综合竞争力的路径机制及时空特征。结果表明：①城市综合竞争力水平逐年提升，具有较强的空间集聚性，高水平城市主要位于下游地区，上游地区的增速最快，呈现“良性追赶”的发展态势；②数字经济能够通过技术创新显著提升城市综合竞争力水平，下游地区数字经济对城市综合竞争力水平提升效应最为显著，并且市场化水平对数字经济影响城市综合竞争力水平具有正向调节作用；③中下游地区数字经济对城市综合竞争力的提升效应高于上游地区，并且影响程度经历了由中间高两边低的分布格局逐渐向东高西低的分布格局转变。因此，应差异化施策提升城市综合竞争力水平，巩固扩大数字经济驱动城市综合竞争力的引擎作用，探索数字经济赋能城市综合竞争力提升的多维路径。

Abstract

Based on the perspective of the ecological niche, the article used ecological, econometric and spatial statistical methods, and taking the Yangtze River Economic Belt as the research object, explored the path mechanism and spatio-temporal characteristics of digital economy enhancing the urban comprehensive competitiveness (UCC) by measuring the levels of the UCC from 2011-2022. The results showed that: 1) The level of the UCC increased steadily, with strong spatial agglomeration. 2) Digital economy could significantly enhance the UCC through technological innovation. 3) The enhancing effect of digital economy on the UCC in the middle and lower reaches was higher than the upstream areas, and the degree of influence had undergone a gradual shift from a distribution pattern of high in the middle and low on both sides to that of high in the east and low in the west.
