The construction of smart stadiums is an important direction for the development of the sports industry. This paper builds a digital empowerment analysis framework for stadiums from the main body of stadium intelligent construction and designs and builds a smart stadium management information system platform. Examine the advantages of VR technology in sports training, process motion capture data, and propose motion recognition technology based on skeletal data. Use the satisfaction index to measure the effectiveness of intelligent transformation applications in sports stadiums that utilize VR technology. We analyze the whole life cycle cost of sports building projects, calculate the revenue and operation cost of intelligent construction of stadiums from the perspective of the composition of sports building projects, and predict the return on investment of intelligent construction of stadiums by combining the investment ratio of different partners. In the dimension of “intelligent service”, the satisfaction score of the training service (VR technology sports training service) is 3.689 with a standard deviation of 0.825, and the return on investment is 17.59% during the 14-year construction and operation period of the project when the share ratio of the partner is 60%.
