Shadow economy as a threat to national security // Financial Markets, Institutions and Risks: Proceedings of the International Scientific and Practical Online-Conference, Sumy, November 20-22, 2021. Sumy : Sumy State University, 2021. P. 63-67.0000-0002-9435-0065https://essuir.sumdu.edu.ua/handle/123456789/89038The shadow economy is inherent in the economic system of any state without exception. However, depending on the scale, it affects the economic and sociopolitical processes in a given country in different ways. In the literature, the allowable size of the shadow economy is 5-10% of GDP, this scale does not cause significant changes or violations in the socio-economic processes of the state. An increase in the size of more than 30% of GDP is evidence of the existence in society of a reproductive system of shadow economic relations, which leads to an imbalance in the economy (Borusevych, 2012).eninc10тіньова економікатеневая экономикаshadow economyTheses
