中国八大综合经济区数字经济发展水平测度、区域差异和收敛性研究

Study on the Level Measurement, Regional Differences and Convergence of Digital Economy Development in Eight Comprehensive Economic Areas of China

当前,区域间数字经济发展不平衡问题显现,过大的数字经济发展差异制约着区域经济的协同发展。运用熵值法、基尼系数分解法以及收敛模型,考察了中国八大综合经济区2010—2021年数字经济发展情况、区域差异及其收敛性。研究发现:我国数字经济发展水平整体呈现上升趋势,八大综合经济区数字经济发展水平也均实现了增长,但各地区之前数字经济发展空间差异较大;全国数字经济发展的总体差异呈下降趋势,北部沿海地区的区域内部差异最大,长江中游的区域内部差异最小;全国以及东北地区、北部沿海地区、南部沿海经济区均存在σ收敛特征;全国与北部沿海地区、东部沿海地区、长江中游地区、西南地区、西北经济区数字经济发展均存在绝对β收敛,但收敛速度不一。研究结论为分析八大综合经济区数字经济时空格局提供依据,对促进区域经济协调发展具有政策启示。

Currently,the imbalanced development of digital economy among regions is evident,and the excessive disparities in digital economy development hinder the coordinated development of regional economy.Utilizing entropy method,Gini coefficient decomposition method,and convergence models,we examine the digital economy development,regional disparities,and convergence trends in China’s eight comprehensive economic zones from 2010 to 2021.The study reveals that the overall level of digital economy development in China is on an upward trend,and the digital economy development levels in the eight comprehensive economic zones have also experienced growth.However,there are significant differences in the spatial development of digital economy among these regions.The overall disparity in digital economy development is decreasing,with the most significant internal disparities observed in the northern coastal region and the least in the middle reaches of the Yangtze River.The Northeast,Northern Coastal,Southern Coastal economic zones exhibitσconvergence characteristics.Absoluteβconvergence in digital economy development is observed nationwide,as well as in the Northern Coastal,Eastern Coastal,Middle Reaches of the Yangtze River,Southwest,and Northwest economic zones,although the convergence speeds vary.The research conclusion provides a basis for analyzing the spatial-temporal pattern of digital economy in the eight comprehensive economic zones,and has policy implications for promoting the coordinated development of regional economy.
