Abstract:
The aim of the article is a comparative analysis of the efficiency of functioning of the national economy on the basis of the «input – output» model and the most important macroeconomic indicators of its development. The indicators of efficiency of the functioning of the economy in 2012–2020 were calculated, built on the basis of the relevant elements of the matrices of the coefficients of direct and total costs of the V. Leontiev’s model. The carried-out analysis of performance indicators has made it possible to allocate periods of their growth and decline, to show that less efficient industries are mainly used in the country’s economy. A comparative study of the features of the dynamics of efficiency of functioning of the national economy and the main macroeconomic indicators of its development is carried out. For this purpose, the corresponding pair correlation coefficients are calculated. The closeness of the relationship between macroeconomic indicators of development and quantitative indicators of the investment climate is also assessed. The obtained low values of the defined correlation coefficients may indicate that the processes of change in the size of the national economy in the specified period are not directly related to such an important factor as the efficiency of its functioning, the investment climate is also not significant for the economic development of the State. In this regard, it is natural to assume that other factors have a decisive influence on the development of the economic system of Ukraine, which requires their further identification and study. In addition to the already known on the basis of the «input – output» model, new indicators of efficiency of functioning of macroeconomic systems have been proposed. As an actual direction of development of the presented material, the analysis of the features of the economic and mathematical content and the ratio of various indicators of efficiency, built on the basis of the model of V. Leontiev, and a clarification of the specific possibilities of their use in the relevant economic studies can be considered.

Keywords: national economy, efficiency of functioning, macroeconomic indicators, investment climate, «input – output» model.
