Abstract: This article reflects the results of a research on the impact of the transportation factor upon the functionality of the local markets on the example of the petroleum products market in the Republic of Sakha (Yakutia). Due to absence of local production on the territory of the region, functionality of the local petroleum products markets completely depend on the level of development of the transportation system with the specificities of the “Northern territories”. The peculiarities of the pricing and specific organizational economic relations within the transportation-logistical system are the results of the impact of the transportation factor. The object of the research is the local markets of petroleum products in the Republic of Sakha. The issues of research of the impact factors of the transportation system upon optimal functionality and development of the local markets with consideration of the specificity of the Northern regions have not been sufficiently studied. The authors determine the key causes of problems in pricing of the petroleum products market, which consists in the territorial disproportions of the level of transportation system and access to these markets; high coefficient of logistics costs of the arctic group of regions in the final pricing of the petroleum products, which leads to uneven competitive conditions in the main petroleum products market.
