The large language model is highland of global technological competition and engine for economic development. As new innovation paradigm emerging in the digital economy era, exploring the mechanism and path of context driven innovation in the industrial architecture of large language model has important theoretical value and practical significance for solving major application and industrialization problems and better supporting high-quality economic development. Based on the theory of context driven innovation, exploring the connotation, core elements, and process mechanisms of context driven innovation in the industrial architecture of large language model industries. It summarizes the specific practical path of context driven innovation in the industrial architecture of large language industries, and verifies and concretizes the practical path through multiple case analyses. It has been found that under the context driven innovation paradigm, the mechanism of innovation in large language model industry architecture can be summarized into four key links: major mission and strategic traction, scenario identification and classification, industrial architecture innovation process, and innovation effects; The innovation of large language model industry architecture under the context driven innovation paradigm covers the systematic integration of technological architecture, the dual transformation of organizational architecture, and the integration of industrial chain architecture. The research results provide important theoretical basis and practical guidance for promoting the higher-level application of large language model and better supporting the high-quality development of the digital economy.
