| 摘 要： | 数字经济是长江经济带实现经济高质量发展、形成区域竞争新优势的重要驱动力,对于数字产业区位的研究则是长江经济带数字化发展的重要议题。本文以长江经济带1994—2019年1375971家数字产业企业为样本,综合利用标准差椭圆、核密度估计、平均最近邻指数及地理探测器等方法,探究长江经济带数字产业空间格局演化规律及驱动因素。结果表明：① 研究期内长江经济带数字产业企业数量大幅增长,呈现“东（略偏北）-西（略偏南）”的集聚发展态势。② 数字产业空间分布差异凸显,总体保持着“上下游城市>中游城市”的分布状态,以“城市群-中心城市”为依托的多核心集聚分布特征愈发明显。③ 数字产业服务化趋势明显,制造型数字产业具有明显的路径依赖,区位分布主要聚集于下游的长三角一带;服务型数字产业则在全域形成以中心城市为核心节点,不断向外围蔓延的态势。④ 长江经济带数字产业空间格局演化受经济社会发展水平及信息化发展潜能两个维度的多种因素影响,前者对于制造型数字产业影响较大,而后者对于服务型数字产业的影响更加明显。此外,驱动因素之间的交互作用亦更为显著。

| Abstract: | The digital economy is an important driver for the Yangtze River Economic Belt to achieve high-quality economic development and form a new competitive advantage. Additionally, digital industry location is an important topic for the digital development of the Yangtze River Economic Belt. Taking a sample of 1,375,971 digital industry enterprises in the study area from 1994 to 2019 as cases, this paper explores the spatial pattern of the evolution of the digital industry in the region and the driving factors behind it by using a combination of standard deviation ellipse, kernel density estimation, mean nearest neighbor index and geographic probe. The results show that: (1) The number of digital industry enterprises increases significantly during the study period, and the spatial distribution of the enterprises shows an “east (slightly north) - west (slightly south)” agglomeration trend. (2) The spatial distribution of the digital industry varies significantly, with an overall distribution of "upstream and downstream cities > midstream cities", and the multi-core agglomeration distribution based on "city clusters - central cities" is becoming more and more obvious. (3) The service-oriented trend of digital industry is obvious. The manufacturing-based digital industry has obvious path dependence, and the industrial layout always gathers downstream of the Yangtze River Delta, while the service-oriented digital industry forms a core node in the central city and continuously spreads to its periphery. (4) The evolution of the spatial pattern of digital industries is influenced by a variety of factors in two dimensions: the level of economic and social development and the development potential of information technology, but the former has a greater impact on manufacturing-based digital industries, while the latter has a more pronounced impact on service-based digital industries. In addition, the interaction between the driving factors is more significant. |
