The present disclosure relates to a frequency spectrum management apparatus, a frequency spectrum management method and a computer-readable storage medium. The frequency spectrum management apparatus in a coexistence system according to the present disclosure comprises a processing circuit configured to determine a plurality of settlement solutions of interference overlapping images according to differences between an interference overlapping image determined by the frequency spectrum management apparatus and interference overlapping images determined by other frequency spectrum management apparatuses in the coexistence system, and to determine a final settlement solution based on the total system utility of the coexistence system and according to the plurality of settlement solutions. By means of the frequency spectrum management apparatus, the frequency spectrum management method and the computer-readable storage medium according to the present disclosure, a settlement can be made for frequency spectrum allocation solutions generated by a plurality of frequency spectrum management apparatuses, such that consistent and rational frequency spectrum allocation is carried out.
