数字经济与区域经济耦合关系的时空演变以及地区差异
The Spatiotemporal Evolution and Regional Differences of the Coupling Relationship between Digital Economy and Regional Economy

本文以30个省份为研究对象，构建2012年至2021年的面板数据，运用熵权法、耦合协调度评价模型、空间自相关分析以及基尼系数来研究我国数字经济与区域经济耦合关系的时空演变以及地区差异。研究表明：第一，数字经济与区域经济耦合协调度从2012年的中度协调阶段上升到2021年的高度协调阶段，区域上呈现东强西弱的特点，东部保持在高度协调水平，而中部和西部均处在中部协调水平；第二，数字经济与区域经济存在空间效应；第三，地区间的差异是数字经济与区域经济耦合协调度在不同区域显著差异的主要原因。
This article takes 30 provinces as the research object, constructs panel data from 2012 to 2021, and uses entropy weight method, coupling coordination degree evaluation model, spatial auto-correlation analysis, and Gini coefficient to study the spatiotemporal evolution and regional differences of the coupling relationship between China’s digital economy and regional economy. Research has shown that firstly, the coupling coordination degree between digital economy and regional economy has increased from a moderate coordination stage in 2012 to a high coordination stage in 2021. The region exhibits a characteristic of strong in the east and weak in the west, with the east maintaining a high coordination level, while the central and western regions are both at the central coordination level; Secondly, there is a spatial effect between the digital economy and regional economy; Thirdly, regional differences are the main reason for the significant differences in the coupling and coordination between digital economy and regional economy in different regions.
