中国数字产业链发展水平、时空特征与区域差异
Development Level of China's Digital Industry Chain,Spatial-temporal Characteristics and Regional Differences
摘要
Abstract
Based on the panel data of 30 provinces in China from 2009 to 2021,this paper uses the entropy method to calcu-late the development level of China's digital industry chain,and then adopts Moran's index and Dagum Gini coefficient method to examine the spatiotemporal evolution trend and regional differences.The results go as below:The development level of China's digital industry chain is fluctuating and rising,but the overall development level is relatively lower.The development level of Chi-na's digital industry chain is highly correlated in space,and most provinces are distributed in the first and third quadrant.There are absolute and relative differences in the development level of China's digital industry chain,with absolute differences gradually expanding and relative differences gradually decreasing.Regional differences are the main reason for the spatial imbalance of Chi-na's digital industry chain development level.On this basis,the paper presents suggestions on creating a new form of modern digi-tal industry chain,establishing a coordinated and interconnected digital industry chain system,and implementing digital industry chain innovation strategies according to local conditions,hoping to provide experience and reference for improving the develop-ment level of digital industry chain.关键词
