An integration between the principles of supply chain management in sport tourism and a sustainability-balanced scorecard leads to the development of guidance and assessment criteria for a city to be a sustainable sport tourism destination. This paper aims to present a sport tourism sustainability management model (STSM) for the development of assessment indices when selecting a city to be developed as a sport tourism city. The model consists of five perspectives, namely the financial perspective, customer perspective, internal process perspective, learning and growth perspective, and sustainability perspective. By using the Delphi technique to obtain a consensus from experts, university lecturers, independent organizations/associations, and business entities in relation to sport tourism management, the researchers define elements to assess complex perspectives for the sustainable development of sport tourism. The results show that there are five perspectives and eighteen elements in relation to the sustainable development of sport tourism. All perspectives and elements have a high consensus, as measured by Kendall’s Coefficient of Concordance (W), of 0.488. To validate the model, the researchers examined the correlation among the five perspectives using a structural equation model and found that both the absolute fit and the incremental fit are satisfactory. As the model aligns and explains empirical data, it can support decision making for management teams, be used to effectively and efficiently draft a strategy for sustainable development in sport tourism, and improve the livelihoods of residents.
