[Research purpose]Key core technologies are of great significance in promoting high-quality economic development,ensu-ring national security,and enhancing international competitiveness.Sort out the main methods of key core technologies identification,summarize the shortcomings of existing research,and provide reference for subsequent research.[Research method]Firstly,the concept and characteristics of key core technologies are analyzed;Secondly,the existing key core technology identification methods are sorted out,and the shortcomings and problems of the existing research are summarized;Finally,suggestions are made for the identification of key core technologies in the future.[Research conclusion]From the perspective of concept definition,key core technologies have the characteris-tics of monopoly status,long-term R&D and technology dominance.From the perspective of identification methods,there are four exist-ing research methods:the method based on expert experience,the method based on patent index,the method based on patent relationship network,and the method based on text mining.Future research should strengthen the exploration of the basic theories of key core technolo-gies,integrate multi-source data from the feature level,improve the automation of the recognition process with the help of artificial intelli-gence technology,and further refine the recognition granularity of key core technologies.
