Economic component of the security of the EU countries and Ukraine

The analysis of existing approaches regarding the essence and content of the concept of "economic security" for complex systems was carried out, on the basis of which indicators for assessing the level of economic security were determined: Labour transitions by employment status, Arrears from 2003 onwards, Inability to face unexpected financial expenses (EU countries); The Global Competitiveness Index (EU countries, Ukraine); integral indicator of the level of economic security (Ukraine).

The methodological tools for the study of the economic security of the EU countries and Ukraine have been determined. It is proved that the economic security of a system at any level of the hierarchy is characterized by a significant number of indicators that complicate its analysis and evaluation. In order to fully take into account the impact of all indicators involved in the study, without significant loss of information, it is advisable to use the procedures of multivariate statistical analysis to assess the level of economic security. Using the taxonomy method, an integral indicator of the economic security of the EU countries was calculated, which makes it possible to assert the existence of disproportions between countries regarding the state of economic security. A matrix of transitions of the EU countries between the states of economic security of the pre-Covid and Covid-periods has been constructed. The economic security profiles of the EU countries and Ukraine were built according to the data of 2019, which made it possible to determine the high level (Netherlands and Sweden) and the lowest (Greece). An attempt was made to determine the threat of losses of the EU countries from military operations on the territory of Ukraine.
