Abstract: This article is prepared the framework of comprehensive analysis of the current state of transport and logistics system of the Sakha Republic (Yakutia). Historically, water transport is the core element of the transport complex in the republic, which handles bulk cargo of interregional exchange to provide population with vital goods, and maintains the functionality of regional economy. Life sustenance of the Arctic zone and conduct of economic activity in the entire territory of the republic depends on the effective operation of inland water transport. The goal of this research lies in the analysis of the key components and objects of inland water transport in the Sakha Republic (Yakutia), as well as determination of the strategic directions of its development in changing conditions. The conducted analysis of the river basin of water transport in Yakutia, the state of infrastructure, and the age composition of transport fleet reveals the major problems of functionality of the water transport in the region. Improvement of the efficiency of inland water transport should be examined from the perspective of increasing the competitiveness of enterprises through implementation of the logistics approach towards rendering services and transportation management. The author comprehensively analyzes and assesses the cargo flows of inland water transport of the Sakha Republic and changes in the logistics of northern freight in the region. Research methodology leans on the general scientific methods of synthesis, generalization, systemic approach, and economic-statistical analysis.

Abstract: The subject of this research is the theory and practice of assessing transport accessibility of the territories of northern regions, where the absence of all-season overland communications render impossible their comparison and analysis. The common type of communications in northern regions are winter/ice roads, which are not usually included in analysis of infrastructure and transportation accessibility of a territory. Inclusion of the variable of seasonal communications is substantiated by the absences of alternatives in northern regions. The tools for assessing transport accessibility of the territory are developed using the integral index method, which allows determining the differentiation of variables of weighted average time and monetary costs on freight transportation. Such method based on the cost and time assessment of the transportation-logistical expenses allows accounting for changes in the transport complex, related to development of transportation network in the region, reflected on all stages of the logistical process. The developed methodological toolset is based on the classic methods of assessment of regional transportation system, while at the same time presents novelty, as it includes the presence of seasonal types of transportation communications in northern regions of the country and their logistical component, allowing to fully assess the peculiarities of transportation systems in the northern regions. The conducted analysis of the variables of the territorial structure of transportation network of the Sakha Republic (Yakutia) revealed heterogeneity in transport accessibility of municipal regions of the Sakha Republic. Results of the analysis of the level of differentiation of transport accessibility of municipalities through methods demonstrated a heterogenic differentiation, influenced by the vastness of the territories, low density of population, as well as sparseness of settlements of the Artic regions among number of other factors.

Abstract: The subject of this research is the territory and practice of the assessment of the regional transportation systems pertaining to the regions of the North, where the absence of year-round land routes makes their comparison and analysis impossible. In the Arctic and Northern regions of Russia, the main transportation system consists in seasonal routes, which are not usually used in the practice of analysis of transportation coverage, accessibility and transportation potential of the territories. These tools are developed by the method of multivariate classification on the basis of multivariate median, taking into account both, a number of quantitative indexes, including the sum of seasonal routes and their productivity, as well as qualitative, which include the level of transportation costs. The developed methodological tools are based on the classic methods of assessment of the regional transportation system, but at the same time, contains novelty, as it accounts for the existence of seasonal types of transportation routes and their logistical component. This allows for a more comprehensive assessment of the peculiarities of development of the transportation systems in the Northern regions.

Abstract: This article examines the questions of territorial structure and administration in the XVIII century of one of the largest regions in the northeast of Russia – Yakutia. Immensity of the territory, geographic and geopolitical location along with rich natural resources, all were of special r importance for Russia. The need for political, economic, and ideological securing of the territory can be seen in the events of the territorial-administrative organization of Russia. Territorial expansion of the borders in the XVIII century that affected both, Siberia and Yakutia, caused multiple administrative transformations. Scientific novelty consists in the comprehensive examination of the questions of territorial-administrative transformations of the northeast of Russia, which allow following the emergence of administrative units, their adjustment to the realities of the joint territories, establishment of administration, and subordination to the tasks of the future development of the region. Administrative reconfiguration was cause by the attempt to find the most optimal forms of administration of the remote territory, as well as integration of Siberia into a unified administrative, legislative, and economic space of the Russian Empire.
