中国数字经济空间动态演进的区域现状

Research on Regional Differences of Spatial Dynamic Evolution of China's Digital Economy

数字经济已成为引领我国经济一体化高质量发展的主要驱动力,立足于国家整体经济及区域经济稳步协调发展的战略。文章基于中国2013—2020年省级数据,运用主成分分析法对中国数字经济进行测度,并运用社会网络分析及核密度等方法对我国数字经济动态演化的空间关联及区域差异进行研究。研究发现:(1)2013—2020年我国数字经济发展整体网络密度稳步提升但依旧处于低水平。(2)中国各省份数字经济发展两极分化,东部与西北、东北等边缘地区存在“数字经济鸿沟”,加之整体关联水平低,分化严重,发达地区对边缘地区的辐射效应较低,差距可能愈发扩大。(3)将其划分为四个板块,发现存在“弱关联”板块,板块间溢出关系及关联度差异悬殊,进一步研究各省份数字经济发展的“中间人”作用,发现各省份承担角色更是“极化”严重。研究结果可为我国持续深化数字经济建设,推动经济协调、稳定、高质量发展提供参考。

The digital economy has become the main driving force for the high-quality development of China's economic integration,and is based on the strategy of steady and coordinated development of the country's overall economy and regional economy.Based on the provincial data of China from 2013 to 2020,this paper uses principal component analysis to measure China's digital economy,and uses social network analysis and nuclear density methods to study the spatial correlation and regional differences of the dynamic evolution of China's digital economy.The research found that:(1)The overall network density of digital economic development in China's provinces has steadily increased from 2013 to 2020,but it is still at a low level.(2)The development of digital economy in China's provinces is polarized.There is a"digital economic gap"between the eastern provinces and cities and the northwest,northeast and other marginal areas.In addition,the overall level of correlation is low,and the differentiation is serious.The radiation effect of developed regions on the marginal areas is low,and the gap may not expand.(3)Divide it into four sectors,and find that there are"weak correlation"sectors,and the spillover relationship and correlation between the sectors are very different.Further study the"middleman"role of the development of digital economy in each province,and find that the role of each province and city is more"polarized".The research results can provide reference for China to continue to deepen the construction of digital economy and promote coordinated,stable and high-quality economic development.
