数字经济对区域高质量发展空间影响效应及耦合协调性分析

Spatial Impact and Coupling Coordination Analysis of Digital Economy on Regional High-quality Development

厘清数字经济对区域经济高质量发展的空间影响效应及其耦合协调性,有利于优化高技术研发空间布局和数字产业发展战略,更好解决区域经济发展不平衡不充分问题,实现高质量发展目标。本文以中国2013~2020年31个省(区、市)的面板数据,构建数字经济与高质量发展水平的指标体系并进行测算,实证考察数字经济发展对高质量发展的空间影响效应。结果显示:我国高质量发展水平呈现东部>中部>西部的布局,并且西部地区高质量发展水平呈现低-低聚集,中部地区不显著,东部地区的江苏省、上海市、浙江省和福建省呈现高-高聚集;数字经济发展对高质量发展水平具有直接效应和间接效应,并且空间溢出效应大于直接效应。进一步构建数字经济-高质量发展耦合系统,耦合协调度结果表明,东部地区最高,西部地区最低,中部地区与东北部地区在二者之间。建议我国高质量发展水平具有低-低聚集和聚集性不显著的地区,要加大数字基础设施的建设与投入;国家在推动数字经济发展和加快高质量发展时,要重视区域发展的均衡性和协调性。

Clarifying the spatial impact and coupling coordination of the digital economy on the high-quality development of the regional economy is conducive to optimizing the spatial layout of high-tech R&D and digital industry development strategies,better solving the problem of unbalanced and insufficient regional economic development,and achieving high-quality development goals.Based on the panel data of 31 provinces and cities in China from 2013 to 2020,this paper constructs and calculates the index system of digital economy and high-quality development level,and empirically examines the spatial impact of digital economic development on high-quality development.The results show that:our country’s high-quality development level presents the layout of eastern>central>western,and the high-quality development level in the western region presents low-low aggregation,the central region is not significant,and Jiangsu,Shanghai,Zhejiang and Fujian provinces in the eastern region present high-high agglomeration;the development of digital economy has direct and indirect effects on the level of high-quality development,and the spatial spillover effect is greater than the direct effect.To further build a digital economy-high-quality development coupling system,the coupling coordination degree results show that the eastern region is the highest,the western region is the lowest,and the central region and the northeastern region are in between.It is suggested that areas with low-low agglomeration and insignificant agglomeration in my country’s high-quality development level should increase the construction and investment of digital infrastructure;when the country promotes the development of the digital economy and accelerates high-quality development,it should pay attention to the balance of development and the coordination.
