Abstract: 【Purpose/significance】To sort out the concepts and identification methods of emerging technologies in domestic and foreign literature, and summarize the characteristics and deficiencies of various methods, so as to provide multi-dimensional perspectives and method references for future research on emerging technology identification.【Method/process】Through comparing emerging technolo⁃ gies with cutting-edge technologies and disruptive technologies, the connotation and characteristics of emerging technologies are clari⁃ fied. Then, it sorts out the emerging technology identification framework from the four levels of data sources, identification paths, iden⁃ tification indexes and effectiveness verification.【Result/conclusion】The four data sources, two identification paths, five types of identi⁃ fication indicators, and four validity verification methods for emerging technology identification are summarized. In the future, it is pos⁃ sible to further explore the formation mechanism of emerging technologies and the integration of multi-source data, and improve the identification path based on terminology using more fine-grained automatic identification methods，as well as strengthen the correla⁃ tion interpretation between identification indexes and technical characteristics, and verify the validity of the identification results.【In⁃ novation/limitation】Comprehensively and systematically sort out emerging technology identification methods, and summarize the mechanism and method model of emerging technology identification paths from themes and terminology units, which is conducive to providing different dimensions of research ideas for emerging technology identification.
