The links between the migration of highly skilled workers and economic growth (in terms of GNI per capita) and the competitiveness of countries have been studied. The study is based on statistics from developed countries and using correlation-regression analysis and modelling, as well as cluster analysis using the package of processing and analysis of statistical information STATISTICA. The analysis found that the immigration of workers with higher education has a significant impact on strengthening the competitiveness and economic development of countries – this is confirmed by the impact of talent migration, which is assessed by the values of case studies (‘The Human Flight and Brain Drain’ sub-index Fragile States Index and ‘Brain gain’ sub-index’ in the Global Talent Competitiveness Index and ‘Highly educated workers’ sub-index in the OECD indicators of talent attractiveness). Their impact on macroeconomic indicators is higher compared to the links with social development indicators. Of course, this does not mean that such links should not be seen as important in public economic development management, as they illustrate the level of efficiency achieved in creating favourable conditions for realizing the potential of highly skilled workers, including pull-factors for their immigration. But in the macroeconomic management of a competitive economy, according to our research, actions aimed at attracting highly skilled migrants have the most significant and obvious impact. Other links can be taken into account and used in modelling for the development of institutional support for proactive migration policy for highly qualified workers.

Population migration is one of the natural phenomena that occurs in society regardless of the form of social and economic system, and is considered within the framework and at the intersection of various sciences. However, military migration has its unique features and a distinct landscape of its processes, occurrences, and ongoing developments. The subject of this research is the complex of problems related to military migration in Ukraine, as well as its impact on the socio-economic development of territorial communities. The article aims to map both visible situations and latent processes in the territorial communities of Ukraine caused by military migration during the Russo-Ukrainian War. It is demonstrated that the consequences of military migration have both positive and negative aspects, thereby becoming a source of conflict and contributing to a decline in living standards within territorial communities. The need to combine the efforts of government bodies, civil society, and stakeholders in a comprehensive study of the consequences of military migration on communities is emphasized to develop effective models and strategies to overcome negative patterns. The fundamental issues surrounding military migration are reexamined to incorporate some of the significant new field data that has surfaced recently and to outline the policy implications of the results.
