The invention discloses a method and a system for controlling network management. The method comprises the following steps: in the network management control system, a topmost network administration user creates an authority label and establishes relations of dependence between the authority label and a network object/object group; an upper network administration user creates or deletes a lower network administration user, and wholly or partly confers the authority label owned by the upper network administration user on the lower network administration user; and when the network administration users carry out the operation on the network object/object group, the network administration users verify whether the authority labels owned by the network administration users are consistent with the authority labels adhered to the network object/object group requesting operation, and only when the authority labels are consistent with each other, the network administration users are allowed to carry out the operation on the network object/object group. The invention can realize the multilevel right distribution and the authority control of network management.
