Different versions of the shifting mode of reproduction models describe set of the macroeconomic production subsystems interacting with each other, to each of which there corresponds the household. These subsystems differ among themselves on age of the fixed capital used by them as they alternately stop production for its updating by own forces (for repair of the equipment and for introduction of the innovations increasing production efficiency). It essentially distinguishes this type of models from the models describing the mode of joint reproduction in case of which updating of fixed capital and production of a product happen simultaneously. Models of the shifting mode of reproduction allow to describe mechanisms of such phenomena as cash circulations and amortization, and also to describe different types of monetary policy, allow to interpret mechanisms of economic growth in a new way. Unlike many other macroeconomic models, model of this class in which the subsystems competing among themselves serially get an advantage in comparison with the others because of updating, essentially not equilibrium. They were originally described as a systems of ordinary differential equations with abruptly varying coefficients. In the numerical calculations which were carried out for these systems depending on parameter values and initial conditions both regular, and not regular dynamics was revealed. This paper shows that the simplest versions of this model without the use of additional approximations can be represented in a discrete form (in the form of non-linear mappings) with different variants (continuous and discrete) financial flows between subsystems (interpreted as wages and subsidies). This form of representation is more convenient for receipt of analytical results as well as for a more economical and accurate numerical calculations. In particular, its use allowed to determine the entry conditions corresponding to coordinated and sustained economic growth without systematic lagging in production of a product of one subsystems from others.
