Abstract
The article presents the development of the basic model of the activity of economic market entities in the context of digitalization.His starting point was the use of a previously developed dynamic probabilistic model of economic systems.With regard to the electric power industry, an analysis of the marginal pseudo-market pricing system used in the Russian economy is carried out.The results of the analysis and modeling of the activities of economic entities in the electric power industry showed the negative impact of marginal pricing on the country's economic system as a whole.An alternative version of direct budgetary support for ineffective market entities is proposed.
