Measurement and Difference Analysis of Digital Innovation Efficiency Based on Provincial Panel Data
Digital innovation is an important driving force for the development of modern digital economy.Based on provincial panel data from 2011 to 2021,a three-stage DEA model is used to measure the efficiency of digital innovation in China,and the Gini coefficient is used to analyze the characteristics of efficiency differ-ences.The research results show that the average comprehensive efficiency of digital innovation in China is 0.147,which is relatively low overall;the overall Gini coefficient of efficiency values is greater than 0.6,indica-ting significant differences in digital innovation efficiency.The reason for these differences is that there are sig-nificant differences in digital innovation efficiency between regions;the higher the number of regional fixed assets investment and Internet users,the higher the efficiency of digital innovation.Based on the conclusion,sugges-tions are put forward to increase fixed assets investment,innovate investment methods,accelerate the construc-tion of digital network infrastructure,improve Internet services,scientifically and rationally distribute industries,and coordinate digital innovation and development among regions.
