Authentication of the Region as the Object of Economic Security in the Context of Economic Development of Ukraine

Abstract

The urgency of the research involves the need to define the procedure for determinationof the region belonging in the system of the regional economic security; depending on thepresented identifier (cluster).The development of discriminative models of the regionauthentication is expedient to define its belonging to particular category of the regionaleconomic security. The objective of this article is to develop the mathematical models ofthe region authentication in relation to the status of their economic security using thediscriminant analysis. The region identification cluster is the indicator of grouping. Thearticle rationalizes the expediency of using the method of discriminant analysis whileresearching the regional economic security according to data of social and economicdevelopment of the region. As a result of clustering of regions by social and economicdevelopment, three statuses of the regional economic security were defined: “good”,“sufficient” and “satisfactory”. The classification functions of authentication of the regionas the object of anti-crisis management for ensuring the regional economic security weredeveloped for the specified classes by method of discriminant analysis. The evaluation ofaccuracy of the obtained functions indicates the expediency of their using. In addition, thearticle describes the authentication procedure of the region as the object of anti-crisismanagement for ensuring the regional economic security. The application ofmultidimensional statistical methods while researching the multi-criteria economicsystems, such as socio - economic development of the region, allows exploring a largenumber of indicators with different measurement units, to identify the homogeneity ofsystem objects. As a result of application of the discriminant analysis’ method, theclassification functions of authentication of the region as the object of anti-crisismanagement for ensuring the regional economic security were developed.

The Impact of Covid-19 on International Trade in Tourism Services in Europe

“…Analysis of the world tourism market allows to conclude that international tourism is developing in close relationship with other spheres of international life and responds to the general economic state of the market and the political situation with an increase or decrease in growth rates (Trunina et al, 2020). The European tourism region is no exception, demonstrating this, among other things, by a sharp decline in tourism economic activity and the uncertainty of the regional economic security (Ivanova, 2018). At the same time, with a rich cultural heritage and diversity, and including some of the most popular tourist destinations and major markets in the world, Europe continues to be the most visited region, hosting half of the world's international tourist arrivals even under COVID-19 and quarantine restrictions.…”
