"MARINE COMPONENT" OF THE SOCIO-ECONOMIC GEOGRAPHY IN MODERN RUSSIA: BASIC APPROACHES AND CONCEPTS
In the 21<sup>st</sup> century, the World Ocean is becoming an important factor in the global socio-economic dynamics and is a priority area of geo-economic and geopolitical interests. Universal manifestations of the 'shift to coast' (of economy, infrastructure, and settlement systems) are also observed in the Russian Federation, with the 'maritime theme' being actively cultivated in Russian socio-economic geography. The article aims to identify and justify the basic methodological approaches and concepts within socio-geographical study of Russia as a 'maritime power'. Particular attention is paid to the 'amphibian' subject-object sphere of socio-economic geography of the World Ocean, the application of the 'Land-Sea' mental dichotomy to modern Russian conditions, as well as the predominantly transnational (and cross-border) nature of aquatic-territorial regional genesis, its manifestations and effects. The article proposes an extended interpretation of the concept 'maritime power of a country' (including its scientific, technological, informational and mental components). The research has formed the idea of the 'maritime borderline of Russia' as a key object of maritime-oriented socio-geographical analysis.
