Publication Date: 2019-09-24Description: The development of the considerable transport and logistics potential of the Kaliningrad region is hampered by several factors. This problem, to which we will refer to as a transport deadlock effect, translates into the limited contribution of transport to the regional economy. Particularly, it manifests itself at the level of regional gross value added, where the contribution of transport is much smaller than one might expect given the significant role the industry plays in the economy of the region. In this study, we examine major ways of increasing the economic efficiency of the regional transport system from the value added perspective. We posit that the structure of cargo handled and the redistribution of value added in favour of regional actors have the dominant influence on economic efficiency. Using our own simulation model and the earlier developed system of transport tariffs and value added calculation for the Kaliningrad region, we produce scenarios and consider changes in value added in the case of selected cargoes carrying intermediate, investment, and consumer goods (as defined in the International Classification for Broad Economic Categories ICT BEC-4). Our calculations show that higher value added and greater economic efficiency of a regional transport system are associated with re-orientation towards investment and consumer goods. The most visible effect is associated with rail and road transport. As to sea transport, the decisive role is played by an increase in the physical volume of cargo handled. The results of this study and its modelling tools can be applied in the analysis of the current situation and in the assessment of the efficiency of transport systems in other regions. Another possible application is the identification of growth conditions for an industry, particularly, when developing projects and proposals for increasing the efficiency of transport services.Keywords: Städtebau, Raumplanung, Landschaftsgestaltung ; Wirtschaft ; Landscaping and area planning ; Economics ; transport system; regional economy; Kaliningrad region; value added; simulation modelling ; Raumplanung und Regionalforschung ; Volkswirtschaftstheorie ; Area Development Planning, Regional Research ; National Economy ; Russland ; Region ; Verkehrssystem ; Ostseeraum ; Wirtschaftlichkeit ; Modellentwicklung ; Simulation ; Szenario ; Mehrwert ; Güterverkehr ; Russia ; region ; transport system ; Baltic region ; economic efficiency ; model construction ; simulation ; scenario ; surplus value ; freight trafficType: Zeitschriftenartikel, journal article -

Publication Date: 2025-01-29Description: Economic security in border regions emerged as a new area of inquiry in human geography, under the supervision of Prof Fedorov and with the active involvement of researchers from Kaliningrad, Rostov-on-Don, Saint Petersburg, Smolensk, and Simferopol, within the framework of the Russian Science Foundation project № 18-17-00112, titled Ensuring the Economic Security of the Regions of Russia's Western Borderlands under Conditions of Geopolitical Turbulence. This study is the first attempt at a comprehensive examination of economic security, considering a multitude of contributing factors: economic, social, domestic and foreign policy-related, ethnic and environmental. The socio-geographical approach to economic security provides insight into its spatial conditionality, informing our studies on regional and sectoral economics. This article examines the Kaliningrad region's economic development from the perspective of its exclave position, border functions and potential for ensuring Russia's national interests. The assessment of the economic security of the region from 2000 to 2019, cited in earlier works, reveals a lack of resilience to external challenges and threats. In this article, we examine these results in the context of economic development quality and determinants, applying structural and resource-oriented approaches. It is demonstrated that, until 2022, the economic development of the Russian exclave did not fully align with national interests due to a prioritisation of international ties, often at the expense of interregional ones. Additionally, the region's openness was increasing, with insufficient attention given to ensuring its sustainability under external constraints. Seeking to address existing shortcomings, this article presents and substantiates proposed modifications that give due consideration to economic security. Specifically, it emphasises functional and structural transformations within the regional management system.Keywords: Wirtschaft ; Economics ; economic security; national interests; factors of economic development; Russian exclave; external restrictions; Kaliningrad region ; Volkswirtschaftstheorie ; National Economy ; Russland ; Wirtschaftsentwicklung ; wirtschaftliche Lage ; wirtschaftliche Faktoren ; Russia ; economic development (on national level) ; economic situation ; economic factorsType: Zeitschriftenartikel, journal article -

Published 2023Staff ViewPublication Date: 2023-05-12Description: This paper summarizes the results of the seminar "Geopolitical Security of Russia: Remarks on the Problem Statement", held on August 26, 2022, at the Immanuel Kant Baltic Federal University, Kaliningrad. During the seminar, the Institute of Geopolitical and Regional Studies of the university announced an initiative to devise a system of monitoring the geopolitical (regional) security of Russia. The debate centred around the development of a conceptual framework and a geopolitical security model as a prerequisite for the system. The discussion also covered other relevant issues, including the definition of geopolitical security and geopolitical space as well as the types of geopolitical threats and vulnerabilities. Another topic on the agenda was the analysis of theoretical approaches applicable to monitoring the geopolitical security in Russia. A constructivist approach based on discursive practices was viewed as the most promising for tracking changes in geopolitical threats. In this work, the emphasis should be placed on regional issues, i. e. the situation in particular regions. Other promising avenues for further research are the operationalization of relevant concepts and the development of a set of indicators of geopolitical threats and vulnerabilities, which Russia has already faced and may face in the future.Keywords: geopolitical security; geopolitical space; geopolitical threats; geopolitical vulnerabilities; geopolitical monitoring ; Russland ; Geopolitik ; Sicherheitspolitik ; Russia ; geopolitics ; security policyType: Sonstiges, other -
