长三角区域数字经济与制造业高质量发展的耦合协调研究

Research on the Coupling Coordination of Digital Economy and High-Quality Development of Manufacturing Industry in the Yangtze River Delta Region

以长三角“三省一市”为研究范围,基于综合赋权法、耦合协调度与障碍度模型,测度了2013—2021年各地的数字经济及制造业高质量发展的综合指数,以及二者的耦合度、协调度与障碍度。实证结果表明:(1)研究区域的数字经济与制造业高质量发展水平不断增长,空间差异性有所减小。(2)历年两个系统间处于高水平耦合阶段,上海、江苏达到了良好协调水平,浙江为中级协调,安徽为初级协调,整体表现为中级协调,而制约各区域协调发展的障碍因子迥异。根据实证结论,提出了相应的建议措施。

Taking the Yangtze River Delta region as the research scope,and based on the comprehensive empowerment method,coupling coordination degree and obstacle degree model,this paper measures the comprehensive index of digital economy and high quality development of manufacturing industry from 2013 to 2021,as well as their coupling degree,coordination degree and obstacle degree.The empirical results show that:(1)The level of digital economy and high-quality development of manufacturing industry in the study area keeps growing,and the spatial differences keeps decreasing.(2)The two systems are in a high-level coupling stage every year,Shanghai and Jiangsu have reached a good coordination level,Zhejiang has reached intermediate coordination,Anhui has reached primary coordination.The overall performance is intermediate coordination,and there are great differences in the obstacle factors restricting coordinated development in Yangtze River Delta.According to the empirical conclusions,the paper puts forward some corresponding measures.
