Demonopolization is a complex of economic and legislative measures of the state to limit the activities of monopolies , to create a competitive environment in the domestic market. Demonopolization is a category of market economy where markets are being liberalized and competitive businesses are encouraged. In all countries of the world, in order to protect small and medium-sized businesses, antitrust and antitrust laws have been adopted. They are not directed against large corporations as such, since the size itself does not give grounds to treat it (the corporation) as a monopoly, but against abuse of its position in the market, which can undermine perfect competition and thereby weaken the national economy.
