基于突变- 融合视角的颠覆性技术主题演化研究

Disruptive technology, as an important part of technological innovation, has become a powerful engine to promote technological change. Identifying and tracking the characteristics and trends of disruptive technology evolution has important research value and practical significance to the state and enterprises. It is helpful for identifying priority areas and resources' rational allocation of disruptive technology. To this end, starting with four characteristics of disruptive technology, this paper introduces theme - timing sequence analysis and patent citation network analysis, and proposes an analysis model for the evolution of disruptive technology themes from the perspective of mutation - fusion. In which, Leiden community discovery algorithm is introduced to identify technology themes. Finally, in order to verify the feasibility and effectiveness of the model, this paper selects the additive manufacturing technology as example to carry out empirical research. The analysis results can provide guidance for the judgment and regular summary of the evolution path in the field. Compared with previous studies, the model in this paper fully combines the characteristics of disruptive technology. Meanwhile, the analysis conclusions of technology topic evolution are more specific and diversified, which can provide a basis for accurately grasping the evolution path and future development direction of disruptive technology topic.
