The objective of the article is to analyze at a theoretical level public marketing in the tourism sector and its impact on business development. After the COVID-19 pandemic, everything indicates that tourism is positioned as a profitable business that has the capacity to boost the development of different dimensions of the economy, hence most advanced countries have developed a tourism marketing policy to promote their different natural, cultural, infrastructure and recreation options. Methodologically it is a documentary and analytical research. The results obtained allow us to conclude that a good marketing strategy is essential when it comes to attracting investments and tourists; however, this strategy is not standard, but will depend on the capacities, resources, hotel infrastructure and, of course, the interests and business development plans of each country. Moreover, the most appropriate way to assess the success or failure of public marketing, that is, that developed by the State and its institutional framework, is to analyze, through concrete empirical evidence, the results of this propaganda strategy with a model very similar to that used in the field of public policy evaluation in general.

The aim of the article is to model the processes of formation of startup ecosystems on the basis of cluster analysis as a basis for developing strategies for their development. The development of startup ecosystems is due to various support systems that are implemented at different levels: international, national, regional, local. The article considers the peculiarities of starting a startup ecosystem in Ukraine and abroad. It is proved that the topic of startups is quite popular in Ukrainian business, as startups are the largest number of innovative and innovative products or services, which is a significant prospect for attracting domestic and foreign investment in the economy. The main approaches to the definition of "startup" and "ecosystem" are analyzed. In a startup ecosystem, all actors involved are connected. Entrepreneurs come together to share ideas and interact with universities to attract future employees, and investors learn to understand which types of entrepreneurs, teams and startups are most likely to succeed and exit, investing in startups to raise new capital. Models of cluster analysis of processes of formation of startup ecosystems are constructed, which gave the chance to generalize ratings of ecosystems of the countries on 5 clusters. The purpose of cluster analysis is the formation of relatively homogeneous groups (clusters) in the space of variables based on a set of models and methods of aggregation of rows of the data matrix. The use of cluster analysis has a certain sequence of actions and involves the use of several methods. The grouping included 96 countries (4 countries that were included in the ranking for the first time were excluded automatically), which created 5 clusters that differ from each other, but have common characteristics within the selected groups. Each cluster is characterized by features. This division into clusters allowed to highlight the features of the development of startup ecosystems, provide characteristics of each group of countries and in the future will be the basis for developing recommendations and formulating strategies for the development of startup ecosystems.

The article identifies the potential of regions competitiveness, taking into account their relationship with specialization and place in the territorial division of labor. It is proved that the region should pursue a competitive policy in the field of economic, organizational, production and technological, business, image and other development tasks. The competitiveness of regions among themselves and in international markets creates an integral, synergistic effect of state eco-nomic policy, and therefore the state in various ways supports the development of the competitive potential of each of its regions. For Ukraine, the problem of assessing the competitiveness of regions is particularly relevant, which is especially felt in the context of trends in decentralization. The development of rational and scientifically sound recommendations for determining the competitiveness of the regions of Ukraine requires comprehensive consideration of foreign and domestic experience in this area, so it is advisable to consider modern methods developed to solve this problem. The authors determine the regularity of a fairly close relationship between the level of competitiveness of the region with a set of indicators of socio-economic potential of the region and grouped the latter into 10 integrated indicators. According to the ranking priority of the Kharkiv region, its potential for competitiveness is at a high level and is able to provide the region with high rates of economic growth. Taking into account the ranking positions of the regions in terms of 10 indicators. The proposed method of calculating the competitiveness indices of regions, according to the authors, is relevant and accessible from the standpoint of obtaining initial data, as evidenced by the use as data sources for calculations of modern statistical and other publications, information from which is freely available. Thus, the location of the regions on the ranking scale of selected indicators can be determined by the fact that in re-gional development there are significant disparities and differences. However, more than half of the regions have their advantages on individual indicators. The study has identified these benefits and each region can use this in its development strategy and in developing measures to increase competitiveness.

The article is devoted to the research of scientific issues related to acceleration of innovative development of spatial economy, the provision of the theoretical basis for the formation of zones of innovation growth of individual territories (regions). The degree of influence of innovations on the nature of the territorial organization of economic activity determines the level of well-being in society. The purpose of the study was to identify the features and contradictions of the current state of the system of territorial organization of innovation activity. The issue of diffusion of innovation has been studied in terms of representing and positioning a separate territory (region) as a subject of economic relations, a multifunctional and multi-faceted economic system, but not as a place of concentration of means of pro-duction and labor. The further development, the symbiosis of the regionalism the-ory, in particular the spatial organization of production, along with the theory and practice of innovative entrepreneurship, is the substantiation of creation and de-velopment of the territorial poles of innovation growth. It is proved that the effi-cient innovation policy in a certain economic space of activity should be based on the functional properties of the forms of spatial organization of production on the one hand, and the placement of productive forces, on the other hand. The idea of the nature and character of the existing forms of modern territorial organization of innovation activity embedded in a kind of network design, which is the projection of production networks in a certain territory, or so-called "place-connected net-works", is explored and developed.
