According to the price formation state of the international market, it can be divided into: world "free market" price and world "closed market" price.
The former is the price reached by independent buyers and sellers without the interference of monopoly and other factors;
The latter is the price formed by buyers and sellers under a certain special relationship;
It includes the allocation price set by multinational companies for tax evasion and other reasons, the monopoly price adopted by monopoly organizations, the price set within regional economic and trade groups and the agreed price under international commodity agreements.
World free market price
The world "free market" price refers to the price that is traded between independent buyers and sellers under the condition that the international monopoly or state monopoly forces are not interfered. The international supply and demand relationship is the objective basis of this price formation.
A "free market" is a transaction in which more buyers and sellers are concentrated in a fixed place and conducted at a specified time according to certain rules. Although this market will also be affected by international monopoly and state intervention, commodity prices are formed here through open competition between buyers and sellers.
Therefore, it often objectively reflects the changes in the relationship between supply and demand of commodities. According to the statistics published by the United Nations Conference on Trade and Development, the prices of 36 primary products, such as the wheat price of the American Grain Exchange, the CIF price of corn (Argentina) in Britain, the FOB price of rice (Thailand) in Bangkok and the delivery price of coffee in new york, are listed as the "free market" prices in the world.
