Globalization and digitalization of the economy requires the transit of the tourism industry to the principles of sustainable development. The most important element of the sustainable development of tourism is its infrastructural model. The composition of the tourist infrastructure is extensive and is associated with all the elements of the destination that provide and stimulate the development of tourism. Therefore, objects of regional infrastructure can be considered as elements of tourism infrastructure. The concept of sustainable development determines the vector of research in the field of tourism infrastructure. The presented study is aimed at identifying the contribution of social, economic and environmental elements of the tourism infrastructure to the sustainable development of the tourism destination. The study used a quantitative approach based on the IPA method (importance-performance analysis). Interest was measured by comparing the level of expectations and the level of performance. The empirical part of the study consisted in conducting an online survey of tourists and stakeholders of the tourism industry in Moscow, St. Petersburg and Kazan, as the country's leading tourist destinations. The results indicate a high assessment of the tourism infrastructure in general by both groups of respondents. Respondents indicated the high importance and current quality of about 70% of the selected key infrastructure elements. At the same time, inconsistency of opinions of groups of respondents is revealed for certain groups of infrastructure. Infrastructure is a basic factor in ensuring sustainable socio-economic development and competitiveness of tourist destinations.
