长江经济带数字经济和共同富裕的耦合协调发展研究

A Study on the Coupled and Coordinated Development of Digital Economy and Common Prosperity in the Yangtze River Economic Belt

基于2013-2021年长江经济带省级面板数据,运用纵横向拉开档次法、耦合协调度模型和Dagum基尼系数分析长江经济带数字经济和共同富裕的耦合协调发展水平时空演化特征,研究发现:长江经济带数字经济和共同富裕发展水平呈现出稳步上升的趋势,但是总体水平较低,且呈现出明显的不均衡性;两个系统的耦合协调发展水平也呈上升趋势,但尚未出现大面积的优质耦合协调,耦合协调水平存在较大的提升空间;两个系统的耦合协调发展的总体差异、区域间差异和区域内差异均呈现下降的趋势,且区域间差异是总体差异的主要来源。

Based on the provincial panel data of the Yangtze River Economic Belt from 2013 to 2021,this paper analyzes the spatiotemporal evolutionary characteristics of the level of the coupled and coordinated development of the digital economy and common prosperity in the Yangtze River Economic Belt by using vertical and horizontal stretches,coupling coordination degree model and Dagum Gini coefficient.The research finds that the development level of the digital economy and common prosperity in the Yangtze River Economic Belt shows a steady upward trend,but the overall level is low and shows obvious imbalances;the level of coupled and coordinated development between the two systems is also on the rise,but there is no large-scale high-quality coupling coordination,so there is a great room for its improvement.The overall difference,inter-regional difference and intra-regional difference of the coupled and coordinated development of the two systems all show a downward trend,and the inter-regional difference is the main source of the overall difference.
