摘要：Increasing competition for resource allocation and adaptability to pressure
from innovation is associated with globalization. Differences in the ability of individual regions
to respond to such challenges create prerequisites for a collapse of optimal fiscal (as well as
currency) zones. The article analyzes the emergence of economic separatism in two Belgian
regions: Flanders and Wallonia. It is noted that differences in the pace of structural adaptation
in Belgium’s regions generate secession movements. This requires an analysis of secession
problems in the context of optimal fiscal zones. Comparison of Belgium and Ukraine in the
context of separatism development is conducted. Conclusions about the differences between
the two countries regarding its causes and consequences are drawn.
