数字产业化和产业数字化耦合协调性研究--以江苏省为例

Research on the Coupling Coordination between Digital Industrialization and Industrial Digitalization——A Case Study of Jiangsu Province

以数字经济产业系统耦合协调理论为基础,研究数字产业化与产业数字化间时序非线性交互关系,分析数字产业化和产业数字化耦合协调机理,构建综合评价指标体系,利用耦合协调度模型测算数字经济的协调发展水平,基于江苏实证分析,测算江苏数字产业化和产业数字化综合发展水平及耦合协调水平。研究表明,2014-2018年期间,江苏数字产业化对产业数字化具有较强的支撑作用,产业数字化对数字产业化也具有较好的拉动效应,虽然在某些年份呈现协调度不高的情景,但江苏数字产业化与产业数字化的耦合度与协调度逐年提高。

Based on the coupling coordination theory of digital economy industry system,this paper studies the time series nonlinear interaction relation between digital industrialization and industrial digitalization,and analyzes the coupling coordination mechanism of digital industrialization and industrial digitalization to construct a compre⁃hensive evaluation index system.This paper uses the coupling coordination model to measure the coordinated devel⁃opment level of digital economy.Based on an empirical analysis of Jiangsu,it measures the comprehensive develop⁃ment level and coupling coordination level of digital industrialization and industrial digitization in Jiangsu.The re⁃search shows that during 2014-2018,1)In terms of Jiangsu’s digital economy,digital industrialization highly sup⁃ports industrial digitalization,2)industrial digitalization also has a good pull effect on digital industrialization,3)al⁃though the coordination degree is not high during some years,the coupling degree and coordination degree of digital industrialization and industrial digitalization of Jiangsu’s digital economy are improving year by year.
