A network energy saving management method includes: A first network management unit determines network energy saving scope information and a first network energy saving mode, and sends a first energy saving control message to a second network management unit, where the first energy saving control message includes the network energy saving scope information and the first network energy saving mode. The second network management unit triggers, based on the first energy saving control message, a target network node set to perform an energy saving operation, so that network energy saving effect of the target network node set and a network performance loss of the target network node set meet the first network energy saving mode.
