As the main participants in disruptive innovation, latecomers are not only committed to driving the promotion and diffusion of disruptive technologies and products in the market, but also have a significant impact on the process of disruptive innovation. Use Grounded theory to identify the key factors for China"s AI latecomers to achieve disruptive innovation, and use dynamic Two-step fsQCA to refine the configuration path for China"s AI latecomers to achieve disruptive innovation during the "12th Five Year Plan" and "13th Five Year Plan" periods. Research has found that (1) "knowledge search", "cross border mergers and acquisitions", "open market", "collaborative integration", "structural adaptation", and "ecological network" are the six key factors for AI latecomers to achieve disruptive innovation. (2) The four configuration paths for AI latecomers to achieve disruptive innovation are: the "technological leap" of "knowledge search - cross border mergers and acquisitions - ecological network" and the "paradigm shift" of "knowledge search - cross border mergers and acquisitions - structural adaptation" during the "12th Five Year Plan" period; The "organizational transformation" of "knowledge search - structure adaptation - ecological network" and the "value creation" of "cross border mergers and acquisitions - structural adaptation - ecological network" during the "13th Five Year Plan" period. Based on research conclusions, relevant research insights are obtained.
