Distinct from the technology-application orientation of application-oriented universities, the core of industry-education integration in research universities lies in innovation orientation and strategic guidance. To address the issues regarding organizational costs and student motivation in existing macro-institutional designs, this study focuses on the micro-organizational level, taking the "Science and Technology Association" at Chongqing University as a case to explore the bridging function of this organizational innovation between macro-design and student micro-growth. The results indicate that the "Science and Technology Association" serves as a vital organizational innovation linking macro-level top-down design with the micro-level student foundation in research universities. Through the "Three Integrations, Three Crossovers, and Three Collaborations" pathway, it constructs educational platforms to broaden students' horizons, solidifies cultivation paths to enhance capacity building, and innovates cooperative mechanisms to promote scenario integration, primarily achieving the "Macro-Micro" connection through three mechanisms: organizational intervention, motivation stimulation, and scenario penetration. The "Science and Technology Association" talent training model has yielded substantial practical achievements and serves as a vivid practice and typical case of industry-education integration in research universities, providing valuable practical references and path insights for constructing a new pathway that effectively bridges macro-level top-down design with micro-level student development.
