Formation of productive forces

Man forms productivity in the process of solving the contradiction between man and nature. Productivity is the ability of man to cause and adjust the material transformation between man and nature through his own activities, which marks the degree to which the contradiction between man's needs and nature is solved and the degree to which man's needs are met. The objectification of man's essential strength, the internalization of nature's material, energy and information, the generation of man's real world, and the transformation and remolding of man's subjectivity constitute the realistic relationship between man and nature and the realistic productivity.

Productivity, as the product of human material production activities in the past, is the result of each generation's practical ability and the established premise of historical activities. It plays a fundamental role in promoting social development, not only in making human material production possible, but also in its continuous development, that is, the improvement of workers' quality, the improvement of production tools and the progress of production technology, so that social production reaches a new level, and the development of productivity to a certain extent will inevitably lead to changes in production relations and even the entire social structure.
