中国省际数字经济规模测算、非均衡性与地区差异研究

A Study on the Scale Measurement,Disequilibrium and Regional Differences of China’s Inter-provincial Digital Economy

研究目标:测算中国省际数字经济规模,并分析其特征、非均衡性和地区差异。研究方法:马克思政治经济学理论、Kernel密度估计、Dagum基尼系数。研究发现:中国省际数字经济规模整体呈上升趋势,横向比较来看,省际数字经济主要集中在数字经济生产阶段,数字经济生产增加值占数字经济总增加值的比重超过50%;纵向比较来看,广东省、江苏省、北京市、四川省和上海市的数字经济规模常年保持领先地位。观测期内,省际数字经济非均衡性波动上升,且有一定的两极分化趋势,东部和中部地区两极分化趋势尤为明显。省际数字经济存在显著地区差异,区域间差异是地区差异的主要来源,平均贡献率达60.01%;中部地区的差异主要来自组内,东部和西部地区的差异则主要来自组间。研究创新:基于马克思政治经济学理论构建数字经济测算框架并完成中国省际数字经济规模测算,进而采用Kernel密度估计和Dagum基尼系数对中国及三大区域数字经济的非均衡性和地区差异进行分析。研究价值:明确了中国省际数字经济发展现状、特征及地区差异,对数字经济政策制定、数字经济区域协同发展有重要意义。

Research Objectives:To measure the scale of China’s inter-provincial digital economy,and analyze its characteristics,disequilibrium and regional differences.Research Methods:Marx’s theory of political economy,Kernel density estimation,Dagum Gini coefficient.The results show that the scale of digital economy of China’s provinces is on the rise.Horizontal comparison shows that the digital economy of China’s provinces is mainly concentrated in the stage of digital economy production,and the added value of digital economy production accounts for more than 50%of the total added value of digital economy.Longitudinal comparison shows that Guangdong,Jiangsu,Beijing,Sichuan and Shanghai have maintained the leading position in digital economy scale for years.During the observation period,the uneven fluctuation of inter-provincial digital economy increased,and there was a certain trend of polarization,especially in the eastern and central regions.There are significant regional differences in digital economy among provinces,and inter-regional differences are the main source of regional differences,with an average contribution rate of 60.01%.The differences in the central region were mainly intra-group,while the differences in the eastern and western regions were mainly inter-group.Research Innovations:Based on the theory of Marx’s political economy,the framework of digital economy measurement is constructed and the scale of China’s provincial digital economy is calculated.Then,Kernel density estimation and Dagum Gini coefficient are used to analyze the disequilibrium and regional differences of digital economy in China and the three regions.Research Value:The paper clarifies the development status,characteristics and regional differences of China’s provincial digital economy,which is of great significance to digital economy policy making and regional coordinated development of digital economy.
