Abstract: The contradictory movement theory of new quality productive forces and new production relations is the creative development of Marxist thoughts on productive forces and production relations in contemporary China's practice and the digital era,which expands and deepens Marxist political economy and embodies the latest practical results of the CPC's continuous exploration of the liberation and development of social productive forces.The contradictory movement between new quality productive forces and new production relations has objective materiality,social historicity,and dialectical unity.The status of new quality productive forces determines new production relations which in turn act on them.The development of new quality productive forces characterized by high technology,high efficiency and high quality inevitably requires the formation of new production relations that are compatible with them to promote the optimal allocation of laborers,labor materials and labor objects.Comprehensively deepening reform is an effective path to form this adaptive relationship.The new quality productive forces and new production relations are interdependent and mutually reinforced,which has become an important driving force to promote the construction of a modern industrial system,high-quality economic and social development,and the realization of Chinese path to modernization.The contradictory movement between new quality productive forces and new production relations is not only a theoretical innovation,but also an important guidance in practice,providing powerful support for solving problems and shaping new driving forces and advantages for development.

Key words: new quality productive forces, new production relations, contradictory movement, comprehensively deepening reform
