Research on Disruptive Technology Recognition of China's Electronic Information and Communication Industry Based on Patent Influence

Abstract

This paper adopts the knowledge map method and selects the field of mobile communication technology and wireless communication technology to represent the electronic information and communication industry for disruptive technology recognition. Through the analysis of keyword co-occurrence network and keyword frequency changes in the relevant literature of CNKI from January 2000 to April 2018 by CiteSpace software, this paper constructs a disruptive technology identification framework for China's electronic information and communications industry from the perspective of technological frontier and technological breakthrough. Using DeWinter Patent Database as the patent data source, this paper further verifies 5G technology and internet of things (IoT) technology from the perspective of patent impact. Finally, the roadmap of disruptive technology development in China's electronic information and communication industry is proposed to provide reference for the follow-up research of China's electronic information and communication industry's disruptive technology.
