It seems that Marx put forward that productivity determines the relations of production, right?

Marx put forward in Das Kapital that productive forces determine relations of production.

Productivity refers to the ability of social members to obtain means of production and means of subsistence with the transformation of nature and society.

Production relations refer to the mutual relations formed by workers in the production process, including the means of production, the organization and division of labor in the production process, and the distribution of products.

First, the status of productive forces determines the relations of production.

First of all, the status of productive forces determines the nature of production relations. What kind of productive forces will eventually form what kind of production relations. The nature, development level and development requirements of productive forces determine the ownership relationship of the means of production, thus determining people's position and role in the production process and determining people's distribution relationship of products. Secondly, the development and change of productive forces stipulates the development and change of production relations. Productivity is the most active and revolutionary factor in the mode of production, and it is in the process of constant movement, change and development.

Second, relations of production react on productivity.

When the relations of production meet the requirements of the development of productive forces, it will effectively promote the development of productive forces; When the relations of production do not meet the requirements of the development of productive forces, it will hinder or even destroy the development of productive forces. We should change the relations of production with the constant changes of productive forces, so that they can promote the development of productive forces at any time.
