First of all, the two are unified, interdependent, mutually conditional, and coexist in the commodity body, and neither factor can become a commodity. Any commodity is a unity of use value and value.
Secondly, the opposition between the two is manifested in the following aspects: first, use value is a natural attribute of the commodity, which provides the necessity of exchange;Value is the social attribute of commodities, which provides the standard and measure of exchange.
Second, use value is not unique to commodities, but is a common attribute of all goods, an eternal category;Value is a unique attribute of a commodity, a historical category.
Third, the existence of value should be premised on the existence of use valueThe existence of use value is not premised on the existence of value.
Fourth, the use value and value of the commodity cannot be owned by either the buyer or the seller at the same time, but can only be attributed to the buyer and the seller respectively.
It can be seen that the use value and value of commodities are mutually exclusive and contradictory. In order to solve this contradiction, it is necessary to exchange it, and only when the exchange is successful can the use value and value of the commodity be realized separately, and the contradiction within the commodity can be resolved.
