A model of the economy based on an interpolated growth matrix

This paper deals with direct and indirect growth rates of sectors and with the interpolated growth matrix of the economy. Its purpose is to determine the model based on the interpolated growth matrix which enables a new approach in the planning of the growth of the economy. The formulation of such a model is useful for the expression of specific structural problems as well as for the extrapolation of system elements into the future. It is characterized by the use of lower and upper projections of growth and mutual relations of sector growths as a basis for programming future sector changes. In contrast to methods in which the direct growth rates of sectors are given, in this case such trends are determined as endogenous variables. At the same time, we use a large amount of data by means of the indirect growth rates in order to describe more completely the dependences among the sectors.
