城市数字经济的双轨驱动与时空分布特征

Two-track drive and spatio-temporal distribution characteristics of urban digital economy

探索城市数字经济的驱动因素对推动数字经济发展具有重要意义.基于除西藏、港澳台地区外的中国265个城市数字经济数据,利用因子分析法分析了我国城市数字经济发展的驱动因素,并考察其时空分布特征.结果表明,数字经济基础设施建设与数字产业发展是城市数字经济的两个重要驱动因素;我国城市数字经济整体呈现增长趋势,但区域差距显著,部分城市的数字经济发展长期处于中低水平,甚至出现倒退的现象;数字经济发展的重心集中在东部地区,其发展速度快于其他地区.改善城市数字经济基础设施建设和发展数字经济产业是促进数字经济发展的两个重要渠道,研究结论为提升城市数字经济发展水平、协调区域发展提供了重要的参考.

Exploring the driving factors of urban digital economy is of great significance for promoting the development of digital economy.Based on the digital economy data of 265 cities in China,excluding Tibet,Hong Kong,Macao and Taiwan,factor analysis is used to analyze the driving factors for the development of China's urban digital economy and examine their spatial and temporal distribution characteristics.The study result shows that digital economy infrastructure construction and digital industry development are two important driving factors of urban digital economy.Chinese urban digital economy as a whole shows a growth trend,but there are significant regional disparities,and some cities have a long history of low-to-moderate digital economy development,or even regression.The center of gravity of digital economy development is concentrated in the eastern region,which develops at a faster rate than other regions.Improvement of urban digital economy infrastructure construction and development of digital economy industry are two important channels to promote digital economy development,and the research conclusions provide important references for improving the level of urban digital economy development and coordinating regional development.
