Tourism is an important factor in the development of the national economy. The share of tourism in the structure of Ukraine’s GDP is 7.8%. Ukraine, having a considerable tourist potential for the formation of tourist flows, is ranked 85th among 139 countries of the world in terms of tourism attractiveness. According to the findings of the World Tourism Organization (UNWTO), the concentration of natural and recreational resources, objects of the world cultural and historical heritage can provide an annual increase in tourist flows to Ukraine by 4-6%.Under the conditions of unstable external environment and unfavorable conditions of the tourism market, an actual scientific task is to develop the theoretical and applied basis for the formation of the national tourism system. Conceptually, this process must be consistent with the strategic understanding of the need to take into account the mental, institutional, cultural and informational influences on the economic interests of entities, which form a functional, sectoral, socio-economic, institutional and environmental subsystem of the national tourism system. This will make it possible to determine target priorities of such activity not only in accordance with the development of destinations, but also taking into account the possibility of obtaining socio-economic effects, in particular, synergistic, multiplicative and cumulative ones.The goal of the study is to substantiate the essence of the national tourism system (NTS) based on the comparative analysis of the definitions of “tourism”, “tourism system”, “economic system”, “national socio-economic system”, which became a scientific foundation for determining the scientific basis of the national tourism system, its subjects and objects, conditions, goals, and results of formation. For the science development it is also important to obtain results on the structure and evaluation of the national tourism system effectiveness.

Global digitalization has led to the formation of a new contour of the economic environment in tourism due to the inevitable and pervasive transformation of socio-economic systems. All this is happening against the background of the synergy of digital and service economies. Therefore, the study analyzes the genesis and world experience of digitalization to determine the areas and advantages of using digital technologies in the tourism business of Ukraine. Systematization, generalization, and surveying were used. Since the main players of the tourism business are tour operators and hotels, and digital technologies are used by entities located in big cities, a survey was conducted among 57 managers of leading tour operators and hotels in Kyiv, Lviv, Kharkiv, and Odesa. The survey was conducted in July 2020–2021 and concerned digital technologies in the business processes. The results showed a dynamic increase in digital technologies, in particular, by an average of 72.2% per year, which reflects their efficiency and dynamics. The leading digital technologies include contactless payments, chatbots, mobile applications, mobile registration, and VR technologies. The data on their 34.6% use as sources of information search, 78.7% as travel planning and organization instruments, and 59.5% as destination orientation instruments are evidence of the large-scale use of digital technologies by foreign tourists. The essence of marketing, economic, innovation, environmental, service, and configuration priorities of digitalization as interdependent drivers for the initiation of the innovation process in tourism has been determined considering the uneven development and fluctuating dynamics of digital technologies.

AbtractDevelopment of cluster structures is a priority for the knowledge and information economy development and an important prerequisite for effective strategic partnership of logistically and geographically related entities of the economic system. The practice of tourism business shows that it is in the conditions of the development of enterprises cluster systems that will be able to form unique competencies, optimally use the resource potential and strategic opportunities, and obtain synergistic and multiplicative economic benefits. Given the situation, tourism clusters development is considered one of the most promising formats of strategic partnership and predetermines the theoretical field of modern scientific research. The need for a constructive rethinking of the mechanisms of economic actors' convergence based on cauterization; definition of preconditions, stages, and processes of formation and development of tourism clusters is an unsolved theoretical and applied problem.The article is devoted to the procedures identification and interpreting the formation of tourism clusters; systematizing the conditions and factors influencing the clasterization in Ukraine. The work developed recommendations for the successful development of tourism clusters, in particular, the author's vision of identifying structural and functional components of the tourism cluster; establishing interrelations and relationships between participants; definition of tourist attractiveness of the destination for the development of cluster initiatives; algorithmization of the participant's entry to the cluster; developing scenarios for the development of tourism clusters in Ukraine. The results of determining the participants' interaction intensity in the tourism cluster are presented, and the effectiveness of the cluster system development based on a set of economic, social and environmental criteria is evaluated.
