The identification of disruptive technologies is of great significance for countries, industries and enterprises to seize strategic development opportunities and form innovative competitiveness.A disruptive technology identification framework is proposed which combines subjective and objective, qualitative and quantitative, and takes 5G technology in the field of mobile communication as an example.?Firstly, CiteSpace software is used for visual analysis of the literature to sort out the hot spots of cutting-edge technology research.?Secondly ,market potential disruptive potential measure index is built from four dimensions including technical novelty, fusion, breakthrough and technology according to the evolution characteristics of disruptive technology.Patent data is used to measure the potential of its disruptive change, and compared with relatively high maturity in the field of technology to identify disruptive potential of cutting-edge technology.The results show that 5G is a potentially disruptive technology in the field of mobile communications.A new idea for the prediction and identification of disruptive technologies is provided.
