Abstract

[Purpose/Significance] The technological leap refers to a form of technological evolution in which technology breaks through the original technological track and achieves technological leap-forward development. Building a quantitative identification model for technological leap helps grasp the trend of technological change and provides support for optimizing the allocation of scientific and technological resources. [Method/Process] Starting from the basic concept and evolutionary characteristics of technological leap, it proposed a model framework and measurement method for quantitative identification of technological leap based on a single patent, and carried out an empirical study in the field of mobile communication. [Result/Conclusion] The empirical results show that, in the field of mobile communication technology, the initial stage of technological trajectory change is not accompanied by a significant increase in the degree of innovation. The technological theme of the leap in different time phases shows differences, mainly focusing on the radio transmission technology, and the management and allocation of communication resources. The direction of the technological leap shows strong diversification trends. The technology leap identification method proposed in this paper can avoid errors in the identification results due to improper subject division by starting from the subdivided patent technology, and the technology analysis based on the ‘leaping’ patent portfolio can reveal the content of the technology leap in a more detailed way.
