数字经济推进区域发展格局演化的内在逻辑

The Internal Logic of Regional Development Pattern Evolution Driven by the Digital Economy

摘要: 本文构建传统经济与数字经济二维评价指标体系，采用熵值法、主成分分析法与ArcGIS自然间断点分级法，探究数字经济驱动下我国区域发展格局的演变规律。研究发现，传统经济发展主要依靠对外开放，数字经济则取决于数字基础设施与经济增长条件。数字经济助推各省经济增长的同时加剧区域分化：东中西差距有所缩小但差距依然显著，南北差距持续扩大，传统南北分界线不断北移。数字经济向城市群集聚，京津冀、长三角、珠三角成为核心高地，呈现中心化空间结构。本文从时空视角开展双维度研究，丰富了数字经济评价体系，厘清了区域发展新特征。

Abstract: This paper establishes a two-dimensional evaluation indicator system covering traditional economy and digital economy. With the entropy method, principal component analysis and the natural breakpoint classification method embedded in ArcGIS, this paper investigates the evolutionary law of China’s regional development pattern under the impetus of the digital economy. The empirical results demonstrate that the growth of the traditional economy is predominantly driven by opening-up, while digital economic development hinges on digital infrastructure and economic growth conditions. Although the digital economy fuels provincial economic expansion, it aggravates regional divergence. The development gap among eastern, central and western China has narrowed moderately yet remains substantial. Meanwhile, the north-south divide keeps widening, and the traditional north-south geographical demarcation line keeps shifting northward. Spatially, the digital economy tends to cluster within urban agglomerations. The Beijing-Tianjin-Hebei region, Yangtze River Delta and Pearl River Delta have emerged as core growth poles, forming a centralized spatial structure. This two-dimensional research from temporal and spatial perspectives improves the quantitative evaluation system of the digital economy and identifies emerging characteristics of regional development in the digital era.
