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.
