The invention belongs to the technical field of computers and particularly relates to an operating privilege inquiry method and terminal equipment. Operating privileges of a target operation are divided according to two or more preset dimensions, and operating privileges of the target operation on each dimension are recorded in a preset operating privilege list; when a user inquires the operatingprivileges of the target operation, firstly, the inquiry conditions, input by the user, of the operating privileges of the target operation on each dimension are acquired, then, operating privilege items meeting the inquiry condition corresponding to each dimension on each dimension are looked up from the operating privilege list, if no operating privilege items are looked up, the current inquirycondition on the main dimension is replaced with an upper-layer inquiry condition, and the look-up process is executed. With the adoption of multiple dimensions and an upwards backtracking operating privilege inquiry mode based on the main dimension, the fineness of inquiry results is improved, and the method can be applied to complex multi-dimensional service scenes.
