Central-peripheral Structuring in Maritime Transborder Regionalization (on the Example of the Baltic, the Caspian and the Black Sea Region)

The processes of cross-border regionalization (including within certain marine areas) are accompanied by further complication of the socio-economic space structure, the multi-velocity dynamics of its components, as well as the effects of polarization and concentration. This context significantly increases the theoretical and applied significance of the center-peripheral analysis, initiating a permanent adjustment of its tools, taking into account the specifics of the formation and functioning of the center-peripheral structures in the marine cross-border regions that outline the Russian border. The article focuses on the identification of the marine component of the center-peripheral stratification of spatial socio-economic dynamics, as well as the substantiation of specific factors, manifestations and effects of the center-periphery dichotomy in the marine cross-border regions of Russia. Priority attention is paid to identifying the common and specific features in the center-peripheral structuring of the Baltic region, the Caspian region, and the Black Sea region. A significant dependence of the center-peripheral architecture (and the place of the Russian coastal territories in it) on the maturity of the cross-border region, the degree of heterogeneity of its morphostructure, as well as the parameters of maritime activity has been established. An assessment is made of the impact on the center-peripheral positioning of innovation dynamics (including the development of the innovation economy sector, the diffusion of advanced production technologies, the digitalization of the economy and society, the generation of scientific knowledge, etc.), as well as geopolitical, ethnocultural and geohistorical determinants. It is shown that the incorporation of a particular coastal territory into cross-border relations objectively raises its status in the national center-periphery hierarchy, without eliminating problematic situations and risks associated with potentially possible (and multidimensionally manifested in the conditions of the Russian maritime border) peripherization.
