Knowledge creation is a process in which the innovation subject continuously absorbs and transforms knowledge, and effectively utilizes explicit and tacit knowledge in different fields. From the perspective of knowledge creation, a SECI improvement model (B-SECI) that fits the characteristics of disruptive innovation is constructed, and the development characteristics and evolution process of disruptive innovation are deconstructed according to the dimensions of knowledge transfer flow and creative evolution, aiming to be more precise Grasp the inner mechanism of the evolution of disruptive innovation. The study found that disruptive innovation mainly includes tacit knowledge and explicit knowledge, following the processes of socialization, externalization, combination, and internalization, and has experienced creative socialization, program externalization, and technology in specific forms. Prototype and final product commercialization stage.
