摘要
本文从系统耦合视角出发,全面剖析数字经济与制造业产业链现代化的耦合协调机理,基于评价指标体系和耦合协调度模型测算二者之间的耦合协调度,并分析其时空特征和空间效应。研究表明:2011~2021年中国数字经济和制造业产业链现代化发展水平呈上升趋势,但区域差异性显著;二者间的耦合协调关系由低度协调升至中度协调,耦合协调度呈现“东高西低、南高北低”的特征;空间自相关分析显示耦合协调度存在显著的空间正相关性,局部空间集聚类型以L-L集聚为主,主要分布在西部和东北区域。为促进数字经济和制造业产业链现代化协调发展,需进一步发挥高值地区的辐射带动效应。
From the perspective of system coupling,the coupling and coordination mechanism of digital economy and manufacturing industry chain modernization is comprehensively analyzed,and the degree of coupling coordination between the two is measured based on the evaluation index system and coupling coordination degree model,and its spatial and temporal characteristics and spatial effects are analyzed.The study shows that the development level of digital economy and manufacturing industry chain modernization in China from 2011 to 2021 is on an upward trend,but with significant regional differences;the coupling coordination relationship between the two rises from low coordination to medium coordination,and the coupling coordination degree shows the characteristics of“high in the east and low in the west,high in the south and low in the north”.The spatial autocorrelation analysis shows that there is a significant positive spatial correlation in the coupling coordination degree,and the local spatial agglomeration type is mainly L-L agglomeration,which is mainly distributed in the western and northeastern regions.In order to promote the coordinated development of digital economy and manufacturing industry chain modernization,it is necessary to further exert the radiation-driven effect of high-value areas.
