Reasons (factors) of regionalization processes in modern European states

The constitutional legal study of the state-territorial structure of modern European states is inextricably linked with the coverage of the problem of regionalization as a trend in the development of forms of state-territorial organization. The processes of regionalization, under the influence of the causes of their origin and development, lead to the transformation (including qualitative changes) of the very form of the territorial organization of the state (the transition from a unitary form to a federal or regionalist one, the formation of territorial (political) autonomy within the state, state of a new territorial unit, territorial disintegration of the state, etc.). In the current conditions of the emerging trend of regionalization, it is especially relevant to identify and study the driving causes (factors) of the emergence and development of regionalization processes. The article contains an attempt to identify these reasons in the form of a certain classification. Three groups of regionalization factors (factors) based on the comparative analysis of the modern European countries (Belgium, Great Britain, Denmark, Spain, Italy, Finland, France, Ukraine, and the former Yugoslavia) are formulated: 1) the reasons associated with the processes of state and legal development nations; 2) the reasons associated with the development of the economy of the regions; 3) the reasons associated with the territorial (natural-geographical) features of the regions.
