The use value and value of commodities are contradictory and unified. On the one hand, use value and value * * * exist in a unity (commodity), and no commodity can be formed without either party. Use value is the material undertaker of value, and the existence of value is based on the existence of use value. Worthless items can have use value, but this is just an ordinary use item, not a commodity. On the other hand, the use value and value of commodities are opposite and mutually exclusive. The purpose of commodity producers is not to use value, but to use value, but to obtain value, it is necessary to produce and use value; Moreover, it is necessary to sell the valuable goods produced, so as to realize the value of the goods from the buyers. For the buyer, what he needs is the use value of the goods, but in order to obtain the use value, he must pay the corresponding value. Neither the buyer nor the seller can obtain the use value and value of the goods at the same time. Because there is a contradiction between use value and value in commodities, all commodities must participate in the exchange process. Only by exchanging and selling commodities can producers realize the value of commodities and consumers obtain the use value of commodities, thus solving the contradiction between use value and value in commodities.
Characteristics of fake and shoddy goods
Commodities under any of the following circumstances are fake and shoddy commodities:
1. counterfeiting a registered trademark;
2. Counterfeiting patents;
3. Piracy and self-control;
4. Forge the place of origin, factory name and address;
5 counterfeit certification marks, international standard use marks, famous and excellent marks, anti-counterfeiting marks and other marks;
6 does not meet the implementation standards;
7. Adulteration, adulteration, shoddy, old and new, and unqualified goods as qualified goods;
8. Implementing the production license system without a production license or forging a production license number;
9. The state explicitly eliminated;
10. Expired, invalid or deteriorated.
It can be seen that the fake goods did not pay the undifferentiated human labor that the original real goods should have. Although some of them are of use value, they are not commodities, because they cannot be traded normally like ordinary commodities, or they do not contain socially necessary labor. Even if they contain a small amount of labor, they are not socially necessary labor in the general sense, but labor spent to obtain illegitimate interests and unequal transactions. It may even be a kind of labor that causes harm, so it can't be recognized by society.
