Regional political studies and regionology in Russia: transit of theoretical approaches to regional political process in the light of international relations of a region and the municipal policy

The article is an overview of the discussion dedicated to the 30th anniversary of Russian regional political studies, which took place in Nizhny Novgorod on May 27, 2021. The problem field of the materials combines their own content of political regional studies, regional studies, as well as the content of studies of municipal politics and the content of international relations, tied to the study of international relations of the region. The authors pay the main attention to the fact that regional policy, as a rather isolated systemic formation, is squeezed between internal subsystems (municipalities) and external for them supersystems (federal policy of Russia, international relations). As a theoretical form of a holistic description of the structure of «subsystems - system - supersystems», tte authors consider the concept of regional stratification of the political space, which allows concretizing the ranges and forms of communication «region - municipality», «region - federal center», «region - actors of international relations» in the context of the concept of a unified system of public authority in Russia.
