Abstract
This paper deals with direct and indirect growth rates of co-operating enterprises and with the corresponding matrix of growth. Its purpose is to determine through indirect growth rates the growth structure of co-operating enterprises and to construct, on the basis of the matrix of growth, a model which enables us to follow and program them. In other words, by means of the matrix of growth or the model which is based on it we can estimate the future development of co-operating enterprises. The conditions of optimality have been determined through linear programming, whereby account has been taken of the upper and the lower limit of development of the enterprise, the available funds and the efficiency of investments.
