Abstract: Based on the scenario theory, this paper explores the theoretical basis, framework design, application scenarios, practical constraints and optimization paths for digital twin (DT) empowering stadiums' intelligent transformation. With the analysis of the concept and applicability of DT technology, the study discusses the theoretical basis of the stadiums' intelligent transformation by DT based on scenario theory. A smart transformation framework has been designed from the spatial foundation layer, data information layer, model function layer, service application layer and user interaction layer. The smart venue manager and service object have been used to analyze its application scenario. Constraints such as an incomplete policy system, outdated cognitive concepts, immature key technologies, and a lack of digital sports talents are idntified. Finally, optimization paths are proposed, that is, strengthening the policy making of the transformation of digital twin stadium, implementing the idea of "people-oriented" in its transformation, strengthening the research and development of key technologies, and improving its personnel training ability, etc.
