Abstract Disruptive technology, which is typically afforded by major breakthroughs in basic sciences, has been identified as a key factor that promotes scientific and technological revolution as well as industrial change. Thus, the basic research origins of disruptive technology must be examined to identify the core foundational disciplines and forecast future technological trajectories. In this context, individual-level innovation subjects is vital in bridging between basic research and disruptive technologies. Considering China’s graphene field as an example, this study investigates the knowledge linkage and group-knowledge heterogeneity between basic research and disruptive technologies from the perspective of individual innovation subjects. First, relevant innovation subjects are identified by screening disruptive technologies and relevant data from scientific papers are obtained. Second, topics are identified using the author-topic model, and the knowledge association between basic research and disruptive technologies is analyzed based on topic similarity. Finally, individual innovation subject groups are classified based on the number of disruptive technology inventions, and the research-interest diversity of low- and high-output innovation subject groups is analyzed using the topic-diversity index, while the author-topic association knowledge network is constructed to examine the group heterogeneity of basic research and disruptive technologies. The results indicate that scientific and technological topics in China’s graphene field have transitioned from a relatively superficial to a more profound development stage. A discernible knowledge link exists between basic research and disruptive technologies in individual innovation subjects, which has progressively strengthened over time. Individual innovation subjects who have invented a varying number of disruptive patents exhibit different topic diversities and extents of topic interconnectedness. Notably, highly productive inventors have gradually expanded their research depth while maintaining their research diversity. Thus, a distinctive research system characterized by a “small-world” effect within the group was developed. The findings of this study provide intelligence support for the identification, cultivation, and development of disruptive technologies as well as for the promotion of disruptive technology-oriented basic research.
