The invention discloses a spectrum resource selecting method and device. The method comprises the steps that a common base station is used for acquiring channel states of sharing spectrum resources shared by a plurality of special base stations, wherein a return link needs to be established between each special base station and the common base station; information to be transmitted of the special base station needing to transmit information is acquired through the corresponding return link; characteristic attributes of the information to be transmitted are determined; a target spectrum resource used for transmitting the information to be transmitted is selected from the sharing spectrum resources according to the acquired channel states and the determined characteristic attributes of the information to be transmitted. The spectrum resource selecting method and device solve the technical problem that in the related technology, interference is caused due to the fact that base stations dispatch transmission information by themselves.
