Based on the analysis of the connotation of the new agricultural business entity, this paper further explains the new characteristics of the new agricultural business entity, such as internationalization, informatization, greening, ecologization, and organizational integration. The new type of agricultural business entity is the innovation of socialist agricultural management system with Chinese characteristics, which has brought new institutional performance to agricultural and rural modernization, and caused changes in the rural governance body and its structure in terms of production relations. The traditional basic subject "villager" has changed to "professional farmer", "homogenization" to "heterogeneity" and "diversification", and governance pattern to "unitary leading and pluralistic participation". These developments and changes reflect the dialectical relationship movement between rural productive forces and production relations, economic base and superstructure. New agricultural business entity, rural governance body and their structural system have become an important basis for rural revitalization.
