: Transport plays an important role in the development of the economy of the region and the country. Creating conditions for the efficient operation of transport and the provision of logistics services is one of the priorities for the Government of the Russian Federation. Transport and logistics complexes of the regions ensure the availability of transport services to the population, the movement of goods along transport corridors, the use of modes of transport, the possibility of warehousing and storage of goods. Thanks to the development of transport network and the smooth operation of transport processes, the functioning of the region's economy is ensured, which has a positive effect on the overall economic growth of the national economy. The paper reveals the concept of transport and logistics complex, its features and functions. A universal model of development of transport and logistics complex of the region is proposed, which takes into account the elements of transport and logistics complex and the directions of its development depending on territorial, resource, social factors and state regulation. The article substantiates the mutual influence of transport and logistics complex and the economy of the region. The article presents an econometric model for assessing the parameters of transport systems, which determines the interdependence of socio-economic indicators of the region and indicators of transport and logistics complex. In the study, the indicators of transport and logistics complex that have the greatest impact on the gross regional product are determined, and the equations of the gross regional product are obtained, in which the indicators that have the greatest impact on its formation are presented. The economic justification of the dependence of indicators of transport and logistics complex and the gross regional product is presented. The negative dependence of the region's economy on the number of road accidents, the operational length of highways with hard and improved pavement, as well as a paradoxical negative dependence on the turnover of motor transport has been revealed.
