Abstract: Disruptive technology, as an important part of technological innovation, has become a powerful engine driving of technological change. How to discover and identify disruptive technologies earlier, is of great significance, which is helpful for enterprises and countries to grasp the opportunities of technological development. For this reason, this paper proposes a technological disruptive potential identification model based on patent bibliometric. Firstly, we summarized the properties and characteristics of disruptive technology. Secondly, based on patent database, we built the quantitative index to characterize technical disruptive properties. The disruptive indexes include technical fusion index, technical novelty index, technical expansion index, and technical influence index. Thirdly, we used entropy method and fuzzy consistent matrix method to quantitative measure disruptive potential of technology. Finally, we choose five technologies to carry out empirical research from three aspects: 1) cooperation of traditional technology with disruptive technology in same field, 2) cooperation of disruptive technologies in different period, 3) cooperation of disruptive technologies in different field. In this way, the feasibility and effectiveness of the proposed method is confirmed. Meanwhile, the empirical research can further demonstrate the applicability of the disruptive potential index.
