我国省域数据要素发展水平评估、区域差异与演进特征OACHSSCD

As a core production factor in the digital economy era,the development level of data elements at the provincial level and its spatiotemporal evolution characteristics directly influence the overall process of coordinated development of the national digital economy.Based on panel data from 30 provinces in China from 2011 to 2023,this study constructs an evaluation index system for the develop-ment level of provincial data elements from four core dimensions:infrastructure configuration,value transformation,industry penetra-tion,standard management.Employing methods such as kernel density estimation,Dagum Gini coefficient decomposition,and spatial analysis,it systematically investigates the sources of disparities and evolutionary characteristics in the development level of provincial data elements.The findings reveal that the overall development level of data elements in China exhibits a sustained upward trend,with the overall disparity showing a fluctuating yet convergent decline.Regarding the sources of disparity,inter-regional differences are the primary contributor to the overall disparity,with the"eastern-western"gap being the most significant.Intra-regional disparities are characterized by the western region exhibiting the largest disparity,followed by the central region,while the eastern region shows the smallest.In terms of spatial distribution,a pattern of"strong in the east,weak in the west,with a gradient decline"is observed.
