中国数字产业效率的地区差异与敛散特征
Regional Differences,Convergence and Divergence Characteristics of China's Digital Industry Efficiency
摘要
Abstract
Based on the concept of digital industry efficiency,this paper constructs an evaluation index system from the two dimensions of input and output,and uses Super-SBM model,Theil index decomposition method and β convergence model to em-pirically analyze the regional differences and convergence and divergence characteristics of China's digital industry efficiency.The results go as the following:The efficiency level of China's digital industry presents a three-tiered distribution characteristic of"east—middle—west"decreasing gradually.China's efficiency differences of digital industry as a whole and in the three regions show a gradually rising trend;the differences between the eastern and central regions gradually narrow,and the differences be-tween the eastern and western regions and the central and western regions show an inverted U pattern,which expands first and then narrows.The intra-regional differences are the main source of the overall differences.Absolute β convergence and condi-tional β convergence are presented in the whole country and three major regions,and the convergence rate is the fastest in the western region,while the convergence rate is slower in the eastern and central regions.关键词
