数字贸易发展与产业转型升级耦合协调的时空演进与空间差异
Spatiotemporal evolution and spatial difference of digital trade development and industrial upgrading
摘要
Abstract
This study measures the comprehensive evaluation index of digital trade development and industrial transformation and upgrading by constructing an evaluation index system for the development of digital trade and industrial transformation.It is based on provincial panel data from 31 provinces(autonomous regions and munici-palities)in China(excluding Hong Kong,Macao,and Taiwan)from 2010 to 2020.It employs the entropy weight TOPSIS and grey correlation dynamic evaluation methods of grey relational degree,as well as exploratory factor analysis method.The coupling coordination degree model is used to measure the coupling coordination status of the two in the national and the eight economic zones.Combined with Dagum Gini coefficient and kernel density estimation methods,the evolutionary characteristics are analyzed from the perspectives of time and space.(1)The coupling coordination between digital trade development and industrial upgrading in China is in-creasing year by year,from a mildly dysfunctional stage to a well-coordinated stage,but with obvious regional heterogeneity.(2)Dagum Gini coefficient analysis finds that regional differences in digital trade development and industrial upgrading show a narrowing trend,and inter-regional differences are the main source of regional differ-ences,and they mainly come from between the three coastal regions and the great northwest regions.(3)Kernel density estimation analysis finds that although the overall regional differences are narrowing,the gap between high level of coastal areas and low level of inland areas is widening,and there is an obvious polarization phe-nomenon,and there are provinces with much higher coupling coordination than others.关键词
