The Hotel Industry of the Russian Federation as an Element of the Development of the Country’s Economy

The purpose of the study is to establish and evaluate statistical relationships between the indexes of the hotel industry as a type of economic activity, and its relationship with other socio-economic indexes of the development of the Russian Federation using mathematical and statistical methods. The relevance of the study is determined by the needs of using official statistics data to identify intra-system connections in the country’s economy as a system or in its individual branches – subsystems, using statistical methods. Materials and methods . The source material for the study was the official data of the Federal State Statistics Service for the period 2000-2023. The article uses methods of mathematical statistics – correlation and regression analysis of variation series of the hotel industry indexes and other socio-economic indexes of the Russian Federation development. Results . The authors have expressed the statistical relationship between the indexes of the development of the hotel industry and other indexes of the development of the country’s economy in quantitative form. High values of correlation coefficients (more than 0.80) of the paired dependence are established for: the number of people accommodated in hotels and similar accommodation facilities with a subsistence minimum and an average wage in the Russian Federation; the country’s total GDP - with GDP per capita, with a subsistence minimum, an average wage and a total number of people employed in production; GDP per capita - with a minimum subsistence level, with an average wage and the total number of people employed in production. A structural model of correlations between the studied indexes has been developed. For some indexes, dependencies have been identified that adequately (with a probability level of 0.95) reflect statistical data for the analyzed period, which can be used to predict the development of the Russian Federation. Conclusion . The conducted research allowed us to conclude that the use of statistical methods in economics should be expanded, as they allow us to obtain new additional knowledge about the objects under study, as well as evidence of the reliability of the results. The novelty of the research lies in quantifying the interrelationships of the characteristics of the hotel industry as a type of economic activity, its external links with some socio-economic indexes of the country, as well as the intra-systemic links of individual indexes of the development of the Russian Federation, in describing the mathematical dependence of the dynamics of changes in some indexes. The practical significance lies in the possibility of using the results in planning the pace of development of socio-economic indexes, in identifying and evaluating the internal and external relationships of systems selected from real life for research.
