Abstract
This article presents the results of a study on regional connectivity in Southern Western Siberia, focusing on indicators of population spatial mobility - a variety of interregional interactions. The study identifies various forms of subregional and interregional connected spaces, including conurbation, and explores the utility of different data sources for analyzing the spatial mobility of the Russian population. The research also incorporates statistical data, detailing the socioeconomic and infrastructural characteristics of the Southern Western Siberian regions. It investigates travel times between regional hub cities by various modes of transportation, such as car, bus, and train. The analysis reveals that the shortest travel times between these hub cities are achieved by car. Additionally, the study demonstrates that all cities in the region have better transportation links with Novosibirsk than one another, indicating the region’s monocentricity in this regard. To determine the migration connectivity of Siberian regions, the study employs Rosstat data to calculate both the absolute size and intensity coefficient (velocity) of interregional migration flows between pairs of regions. The study finds that regions with stronger migration links between them exhibit higher connectivity. Moreover, the presence of several pairs of territories with intense migration exchanges suggests a polycentric pattern in macroregional migration interactions. Using sociological data obtained through telephone surveys of the population in Tomsk Oblast and Altai Krai in 2021, the study characterizes spatial mobility. It examines parameters such as intensity, travel direction, modes of transportation used, and the purpose of travel for episodic trips outside the region. The analysis reveals that the structure of priority travel directions for episodic mobility aligns with those of intensive migratory flows. Passenger cars are the predominant mode of transport for episodic trips, and the primary goals of such mobility are social, recreational, and labor-related. Ultimately, the study underscores that regional connectivity through population mobility is primarily driven by the desire to maintain social connections.
