摘　　要：从数字基础设施、数字产业发展和数字融合应用三个方面构建数字经济指标体系,并运用熵权法对2012-2021年我国省域数字经济水平进行了测算,并采用自然断点法对数字经济水平进行空间上的分析。运用Dagum基尼系数法和Kernel密度估计法对全国和三大区域数字经济水平的地区差异和差异演进过程进行了分析。结果表明:我国省域数字经济水平不高但总体呈现上升趋势;省域数字经济水平存在明显的区域不平衡,正面临“数字鸿沟”问题;我国数字经济水平总体差异呈减小趋势,差异来源贡献度表现为区域间差异最大,区域内差异次之,超变密度最小;我国整体数字经济水平和三大地区的数字经济发展水平同样存在非均衡性,且中部地区的绝对差异最为明显,说明中部数字经济高低省份间的差距存在一定的扩大趋势。The digital economy indicator system is constructed from three aspects of digital infrastructure,digital industry development and digital integration and application,and the entropy weight method is applied to measure the level of digital economy in China's provinces from 2012 to 2021.The entropy weight method is used to measure the level of digital economy in China's provinces from 2012 to 2021,and the natural breakpoint method is used to analyse the level of digital economy spatilly.The regional differences and the evolution process of the diferences in the digital economy levels of the whole country and the three regions were analysed by using the Dagum Gini coefficient method and the Kernel density estimation method.The results show that:China's provincial digital economy level is not high but generally shows an upward trend;there are obvious regional imbalances in the provincial digital economy level,which is facing the problem of"digital divide";the overall diferences in China's digital economy level show a decreasing trend,and the contribution of the sources of differences is shown as"inter-regional differences are the largest,intra-regional differences are the second largest,and super-division differences are the most important"'.The overall difference in the level of China's digital economy is on the decrease,and the contribution of the source of difference is shown as"the largest difference between regions,the second largest difference within regions,and the smallest hypervariable density";the overall level of China's digital economy and the level of digital economic development of the three major regions are also unbalanced,and the absolute difference in the central region is the most obvious,which indicates that there is a certain tendency to expand the gap between high and low digital economy provinces in central China.
