The support of the development and enlargement of new agricultural management entities needs the combination of long-term cultivation and short-term support, whose middle-term and short-term support should be pertinent, dynamic and flexible. Because of the fuzzy boundary of some new agricultural management entities, because they are in the process of development and change, the expansion of their business and methods as well as the integration of their business make their uniformly accurate classification difficulty. The unclear classification of new agricultural management entities in theory and practice causes the phenomena of recent-seeking and reverse selection in the process of the implementation of “the support policy”, which affect the role of policy effect and which are not conducive to the construction of modern agricultural business system. The optimization of the policy system of short-term support of new agricultural management entities should further be pertinent and flexible, can try to combine “the supporting of the entities” and “the supporting of the items”, standardize the entities management and set up credit evaluation system for agricultural management entities.
