Abstract
This paper provides some results of generalizing the theory of parametric regulation to the classes of nonautonomous continuous- and discrete-time dynamic systems. We present assertions on the existence of solutions to a series of variational calculus problems and on the continuous dependence of performance criteria on uncontrolled functions. The computable general equilibrium model (CGE model) of national economy sectors serves for illustrating the efficiency of the proposed parameter identification method for high-dimensional mathematical models. And finally, the CGE model of national economy sectors is used to analyze the sources of economic growth and to demonstrate the efficiency of the theory of parametric regulation for elaboration of government’s policy in the field of economic growth.
