The article proposes to characterize the place and role of the service sector in the implementation of national goals of economic development for the period up to 2030, a method for determining a quantitative assessment of indicators of development of the service sector, based on the use of model tools based on the apparatus of the input-output table system. The current state of the service sector in the country is briefly described. The service sector in the article is understood as a set of types of services presented in the table of the use of goods and services in basic prices from the system of input-output tables for 2017. The article shows the place of certain types of services in the implementation of indicators of national goals of economic development. For experimental calculations based on the initial table of the use of goods and services at basic prices from the system of input-output tables for 2017, a worksheet was constructed in which some types of economic activities and products were aggregated into conditional sectors of the economy, and from some types were singled out some, directly involved in the implementation of national goals. Calculations according to the worksheet allowed us to quantify the impact of growth in the volume of services on the value of gross value added and the hypothetical values of investment resources required to achieve indicators of national goals.

The article describes one of the possible methods for a generalized assessment of the state of the service sector in the regions, based on the use of the principal component method. For calculations, a matrix was formed that included indicators characterizing the state or level of development of the service sector in the country's regions from 2005 to 2018. Based on the results of the component analysis, 7 main components were identified whose statistical indicators for the highest factor loads allowed them to be correctly interpreted into generalized indicators. According to the normalized values of these indicators, five groups of regions from regions with low to regions with a high level of development of the service sector were identified according to a certain rule. The calculations made it possible to draw a conclusion about the average level of development of the service sector as a whole throughout the country on a Russian scale. The place and level of development of services in the Altai Territory is described in detail.
