| Аннотация | For the Russian Federation, as the largest country in terms of area, the task of strengthening transport connectivity of territories: centers of economic growth, urban and rural areas, settlements within urban agglomerations, etc., is of exceptional importance. It is especially acute in the conditions of growing external sanctions pressure, which caused the need to multiply the strengthening of inter- and intra-regional ties of economic, migration, socio-cultural, scientific and technological nature. The aim of the research is to assess the impact of road transport connectivity on the economic growth of Russian regions. We used general scientific methods (analysis, synthesis, generalization) and methods of spatial econometrics to achieve it. In particular, we substantiated the existence of clustering of regions in the country space by level of per capita GRP and key indicators of motor transport connectivity based on the results of calculation of global and local Moran’s spatial autocorrelation indices. As a result of the construction of multiple regression models with random effects with spatial lags (SAR, SEM, SDM, GSPRE models) and without them, the article shows that the greatest positive and statistically significant influence on the GRP of its subject is exerted by the factor concerning location of the region within the North of Russia, and on the GRP of other regions – by the density of highways. The scientific significance of the study consists in proving that the economic growth of each region of Russia in the period 2014–2022 was influenced by the level of intra-regional transport connectivity of both the subject itself and other regions. The results of our work contribute to the development of ideas about the impact of spatial factors on the economic growth of Russian regions and can be used by researchers in conducting research on similar topics, by public authorities in the development of strategic documents and specific projects for the development of territories
