Abstract: Under the conditions of market economy, the bigger role in the settlement system belongs to agglomerations – clusters with economic, cultural and migration ties, reflected in economic literature and practice of government administration. At the same time, the analysis of particular problems emerging in formation of transborder agglomerations along with articulation of the problem of transborder agglomerations at the regional level are missing. The article examines the borders and composition of the Almetyevsk-Oktyabrsky, Kamsky and Southern-Transurals agglomerations located in the western and eastern borders of the Republic of Bashkortostan. The existing problems pertinent to formation of the indicated agglomerations and ways for their solution are demonstrated. The connectedness of separate municipal settlements that form one or another agglomeration is determined through assessment of the passenger traffic. The presence of transportation lines and history of economic development of the region are also taken into account. For the first time within the economic literature the borders are defined for the proposal to form Almetyevsk-Oktyabrsky, Kamsky and Southern-Transurals agglomerations. Timely determination and necessary support will allow better exploiting their potential, as well as increasing the level of socioeconomic development.
