Example: China's economic system reform is the inevitable result of the contradictory movement between productive forces and relations of production. China's socialist relations of production are basically suitable for China's productive forces, thus promoting the development of productive forces.

productivity can be simply understood as productivity. For example, early humans could only use some fish bones as needles to polish stones for knives and axes. Then people learned about ironmaking, copper making and so on. Modern people invented the steam engine, musket and so on. Jet Li's Huang Feihong series has this historical image.

The mode of production is the relationship between people's exchange, competition, cooperation, employment and employment in production. Business people should know these things best. Those businessmen are all sociable.

Economic relationship is only one of the relationships between individual organizations, so it cannot be equated with social relationship.

"With the acquisition of productivity, people change their own mode of production, and with the change of mode of production, they change the economic relationship that is only the inevitable relationship of this particular mode of production".

This is what Marx said: "Productive forces determine the relations of production". For example, we often hear the famous saying: "Hand grinding produces a society headed by feudal lords, while steam grinding produces a society headed by industrial capitalists". The productivity level of hand grinding will produce and eventually will inevitably produce the mode of production and relations of production in feudal society to replace the old mode of production and relations of production.

Only with the productivity level of steam mill will the capitalist mode of production and relations of production be produced, which will eventually replace the old one, that is, productivity determines relations of production. Reactively speaking, the production relations that adapt to the development of productive forces promote the development of productive forces, while the production relations that do not adapt to the development of productive forces hinder the development of productive forces.

therefore, productivity determines the relations of production, and relations of production react on productivity.
