Abstract: Relying on comprehensive deepening of reform to develop new production relations is an inevitable choice to adapt to the new changes in the movement of fundamental contradictions in Chinese society in the new era. From the perspective of possibility, both of them take the liberation and development of new quality productive forces as the core standard, meet the people's growing needs for a better life as the value attribution, and are unified in the practice theme of Chinese path to modernization. The new production relations are not only a complex system containing various elements in production activities, but also an important link in the organic structure of human social development. From a theoretical perspective, it is necessary to rely on holistic reforms to construct a multidimensional and three-dimensional new type of production relationship; we need to rely on expansionary reforms to enhance the digital interactivity of new production relations; we need to rely on collaborative reform to clarify and improve the focus of the new type of production relations in grasping the logic of the role of“productivity-production relations-superstructure”. From the perspective of practical path, in the process of further deepening reform comprehensively, we must adhere to and improve the socialist basic economic system, and construct a new type of production relations that are compatible with socialism; establish a sound system and mechanism for developing new quality productive forces according to local conditions, and form a new type of production relationship that is compatible with new quality productive forces; accelerate the construction of institutional mechanisms to promote the development of the digital intelligence economy, and develop new production relations that are compatible with the digital intelligence age.

Key words: new quality productivity, new production relations, deepening reform comprehensively, the fundamental contradiction in society
