Abstract
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.关键词
