The interaction and contradictory movement between productive forces and production relations reflect the essential and inevitable connection between them, that is, production relations must adapt to the laws of productive forces.

1, productivity determines the relations of production. First of all, the status of productive forces determines the nature of production relations. Secondly, the development of productive forces determines the transformation of production relations.

2. The relations of production are counterproductive to productivity. When the relations of production are suitable for productive forces, it promotes the development of productive forces; When the relations of production do not adapt to the situation of productive forces, it hinders the development of productive forces.

The interaction between productivity and production relations constitutes the contradictory movement of production mode: production relations are basically suitable for productivity, to be basically unsuitable, and then to be basically suitable after transformation. Expand internal adjustment and external substitution here.

Second, the significance

1, theoretical significance: this law determines the fundamental measure of social progress-productivity standard.

2. Practical significance: This law is an important basis for Marxist political parties to formulate their lines, principles and policies.
