Use value is the natural attribute of commodities. Marxist political economy believes that the use value is created by specific labor and is incomparable in quality. For example, people can't tell which is more valuable, rubber or banana. Use value is the material basis of value, which together with value constitutes the duality of goods.
Labor force:
The duality of labor (duality of labor) is the dual attribute of concrete labor and abstract labor in producing goods. Specific labor refers to labor with different production purposes, labor objects, tools, operation methods and production results. The use value of goods produced by specific labor. Abstract labor refers to undifferentiated general human labor.
Abstract the value of goods produced by labor. Concrete labor and abstract labor are two interrelated and opposite aspects formed in the same labor process. Marx founded the theory of duality of labor, which made the labor theory of value put forward by the bourgeois classical political economists Adam Smith and david ricardo become a completely scientific value theory.
The object of labor refers to the object corresponding to labor itself, such as cultivated land and textile cotton. Includes two categories. First, natural substances, that is, natural objects that have not been processed by human beings. One is a product that is processed by human labor and used as raw material.
Marx's Political Economy;
Marxist political economy is an important part of Marxism. Its essence is to reveal the objective economic laws scientifically, which is also the basic task of economics. If we successfully understand the economic law, we can use it to actively transform the world and benefit the people. The deeper and more comprehensive our understanding of economic laws, the more free we can act and give full play to our subjective initiative, so as to achieve the purpose of better realizing economic interests in practice.
