基于技术-经济范式的数字经济发展水平测度与区域差异研究

Measurement of Digital Economy Development Level Based on Techno-Economic Paradigmresearch on Regional Differences

本文基于数字经济的技术-经济范式结构构建数字经济评价指标体系,采用熵权TOPSIS法测算2012~2020年中国数字经济发展水平,运用Dagumn基尼系数和方差分解法探究其区域差异来源和结构差异来源。研究发现:(1)研究期内中国各省市、区域数字经济发展水平不断提升,华东地区发展水平最高,中南、华北地区次之,西南、西北、东北地区数字经济欠发达;(2)研究期内中国数字经济发展总体差异不断缩小,区域间差异是总体差异的主要来源且其贡献率不断提高;数字经济发达地区的区域内差异更显著;数字经济发达地区与欠发达地区的区域间差异最为明显;(3)华北、华东和西北地区数字经济发展差异的主要结构来源是社会应用体系和核心产业体系,中南和西南地区则是核心产业体系和数字技术体系。

In this paper,based on the techno-economic paradigm structure of the digital economy,constructs a digital eco⁃nomy evaluation index system,uses the entropy right TOPSIS method to calculate the development level of digital economy from 2012 to 2020,and uses the Dagmon Gini coefficient and variance decomposition method to explore the sources of regional and structural differences.The research findings that:(1)the level of digital economy development in China has been continuously improved during the study period,the highest level of development in East China,followed by Central and South China,and the digital e⁃conomy in Southwest,Northwest and Northeast China is underdeveloped;(2)during the study period,the overall difference in has been narrowing,and regional differences are the main source of overall differences and their contribution rate is increasing;the regional differences in developed digital economy areas are more significant;and the regional differences between developed areas of digital economy and less developed areas are the most obvious;(3)the main structural sources of the differences in the develop⁃ment of the digital economy in North China,East China and Northwest China are the social application system and the core indust⁃rial system,and the main structural sources in the central and southwest regions are the core industrial system and the digital techno⁃logy system.
