Abstract As an important driving force for a new round of scientific and technological revolution and industrial transformation,the digital economy has become an important engine to promote the development of new quality productivity.Therefore,this paper focuses on the innovation of electronic information industry,the core industry of digital economy.Based on the analyst reports of the top 100 enterprises in the electronic information industry listed in A-shares,this paper uses the method of text information mining to examine the basic characteristics and development trend of the overall innovation and innovation types in China's digital economy.The results show that the overall innovation of the core industries of China's digital economy is currently showing the characteristics of rapid progress,radical innovations in many subdivisions such as 5G technology,chip manufacturing,artificial intelligence and other fields burst out,and incremental innovation and integration of self-developed disruptive technologies in the fields of lithium batteries,electronic display and optical fiber and cable have achieved a typical sense of “curve overtaking”.More importantly,the method of measuring innovation based on the text information mining of analyst reports not only overcomes the problems of patent strategic disclosure and patent information lag in the digital era,but also makes up for the technical omission of the measurement of patent innovation that has not been published,which is a new breakthrough in methodology.
