The article presents the author’s view of the impact of globalization, internationalization, transnationalization on the development of the international tourism industry with the substantiation of the features of institutional transformations caused by large-scale, structural and other changes in the world economy, in particular, the analysis of the development of the tourism industry of the leading countries, which are centers to attract tourist flow (France, USA, Spain, China, Italy), as well as Ukraine. As a result of correlation and regression models, the potential of the industry and its investment attractiveness were established. It is proved that within the countries’ economic activity, the tourism sector makes a significant contribution to the creation of the gross national product. Characterizing the coefficients in the multivariate regression equation, it can be stated that the most significant impact on GDP is the factor of “Income from international tourism”, since for all countries, it has a positive value greater than one. As for such a factor as “Total investment in the tourism industry”, for all but Ukraine, this factor is characterized by a negative impact on GDP, which determines the high costs of infrastructure development, which are not always paid off by the income of the incoming tourist flow in the short term.
In recent decades, the socialization of economic development has become one of the key trends in globalization and, at the same time, a multilevel, structured and institutionalized process. Theoretical approaches to the essential identification of the social economy are generalized and a multi-criteria format of evolution of its models is proposed, based on social justice, responsibility and solidarity, social mentality and culture, social unity and optimism, social security, climate and comfort. The current configuration of the sustainable development paradigm with its subjective determination is outlined. The results of cluster modeling according to global indices of human development, social process, economic freedom, well-being of the elderly, happy planet, happiness and gender gap are presented. Social attention is paid to the empirical comparison of countries in terms of social optimism using global indices of happiness and a happy planet. The results of the empirical analysis are summarized in the disposition of the Anglo-Saxon, Scandinavian, continental, Mediterranean and transitive models of the social economy, which need qualitative renewal in the process of their global scaling.
