МОДЕЛЬ ЧАСТКОВОЇ ЕКОНОМІЧНОЇ РІВНОВАГИ РИНКУ АВТОМОБІЛЬНОЇ ПРОДУКЦІЇ УКРАЇНИ

The purpose of the article is to substantiate the concept and to build a model of partial economic equilibrium of the automotive products market by market segments (cars, trucks and buses) on the basis of the Walras and Errow-Debre equilibrium models. The provisions and limitations of the Walras equilibrium model are considered and analyzed. The market of automobile products of Ukraine is researched, trends of its change are identified and the main types of restrictions regarding its functioning are identified. The possibility of applying a modified model of the general market equilibrium to describe the functioning of the automotive market is established, as well as the substantive conceptual provisions for the construction of the partial economic equilibrium model are substantiated. The developed model describes the interaction of market economy actors in the production and consumption of automotive products during the annual cycle. The conditions of equilibrium of demand and supply of automobile products in the domestic market are outlined, taking into account the openness of the Ukrainian economy, and the restrictions on the solvent demand of the population are shown. The role of the state as an influential side of interaction, aiming to obtain maximum budget revenues through the formation of an adequate tax policy, is argued. Given the role and importance of the development of the automotive industry as one of the strategic sectors of the Ukrainian economy, modeling of the economic equilibrium of the automotive market is of particular importance. The developed model of partial economic equilibrium is based on the formed conceptual provisions on the conditions of functioning of the market of automobile products of Ukraine and describes the market interaction of its three participants – consumers, manufacturers and the state. It can be interpreted as an analytical reflection of the process of production and consumption of automobile products during a one-year cycle of interaction between market economy actors. Reflection in the model of institutional constraints, which describe the role of the state in the process of seeking economic equilibrium, helps to increase its adequacy to real market conditions.
