The development of the economy of the Russian Federation in modem conditions is based on the development of the economic systems of the regions. The decentralization of political power and the denationalization of the economy that take place in the process of reforms objectively lead to the shift of the center of gravity in making decisions on key economic and social problems of the territories directly to the regions. In the economic system of each country there are always branch blocks that play the most important role in shaping the trends of socio-economic development. In Russia, they include a complex of resource use sectors, electric power industry, as well as petrochemical industry. At present, they are the basis for the development of new industries and the basis for the modernization of traditional branches of the economy. The petrochemical complex of the country, representing one of the most complex complexes of the national economy, is a strategic branch of the Russian economy since it is to a certain extent connected with national economic security, as well as with environmental protection and a number of other socio-economic indicators of the sustainable development of economic systems. One of the main features of the development of the petrochemical industry at the present time is a sharp increase in its scale. Over the past five years, the production of chemical and petrochemical products has grown more than 1.5 times. The petrochemical complex is the base segment of Russian industry, which lays the foundation for its long-term and stable development and has a significant impact on structural changes in the economy, which have a significant macroeconomic effect and affect the level of national competitiveness and the growth rate of the economy as a whole. In this regard, the task of developing methodological bases for the functioning of the petrochemical complex within the framework of effective resource use, identifying current trends in its development, is an actual scientific task, the solution of which has the most important organizational management significance for the development of the regional economy and the successful implementation of the program for Russia's transition to sustainable development. In the light of the above, a study of the issues of the influence of the petrochemical complex on the development of the region's economy is a particularly urgent and important task requiring close attention and solutions.
