The invention discloses a method for implementing dynamic regulation of authority items. The method comprises the following steps: generating authority codes corresponding to the authority items according to the authority items of an authority main body and storing the authority codes in a compound document manner; receiving the regulation request on the authority items which is sent by the authority main body, loading the authority codes corresponding to the authority items, and then providing the authority codes to the authority main body; and receiving the authority codes corrected by the authority main body, and then accordingly regulating the corresponding authority items according to the corrected authority codes. In the invention, the mode of dynamically loading the authority items is adopted to achieve dynamic regulation of the authority items; the regulation process is simple, and no additional maintenance cost needs to be invested by a developer; the mode of storing authority files based on a compound document and the authority codes is adopted; and on the premise of satisfying performances, the invested cost of the whole authority system is lowered, and the applicability of advanced control software is improved.
