In response to China’s dual carbon and digitalization strategies, this study proposes the DTF (Dual-aspects synergy, Three-dimensional linkage, Four-chain integration) educational and teaching model to cultivate interdisciplinary business administration talents in science and engineering universities. Grounded in CDIO and OBE frameworks, the DTF model integrates digital and green competencies across curriculum design, practical training, and intelligent evaluation. It restructures the knowledge framework into a “triple helix” system, builds a layered “virtual-real” practicum platform, and establishes a data-driven quality control mechanism. Through “three-dimensional linkage” and “four-chain integration”, the model forms a sustainable co-education ecosystem. Implementation results demonstrate improvements in curriculum relevance, student innovation capacity, graduate employability, and institutional reform outcomes. The model has been widely adopted across regional institutions, providing a replicable pathway for advancing interdisciplinary business education in the context of industrial transformation and new liberal arts construction.
