Limit Cycle, Trophic Function and the Dynamics of Intersectoral Interaction

An article develops an idea of implementing the trophic functions in Volterra’s “predator-prey” model to the linked intersectoral dynamics of the outputs. The concept of trophic functions and limit cycles are used as key factors in defining the parameters of stable economic dynamics. Two trophic functions for “cars-rolled steel” and “cars-oil products” were built in the article. These empirically based trophic functions were analytically reviewed and constructed in the article providing a tool in the analyses and forecasting of the linked dynamics of the parameters under consideration.
