The present application belongs to the technical field of supply chain collaborative management, and discloses a method and system for bi-directional synchronization and modification of logistics and cargo information. Before the supplier completes the delivery, the method allows the supplier to modify or delete the bound logistics information; the operation instruction synchronously triggers the state rollback of the bound cargo information, so that the cargo information returns to the state of waiting for delivery and is unbound; all changes are ensured to be complete and persistent through atomic transactions; finally, based on the transaction success signal, the system pushes the differentiated synchronization information to the related demand side in real time. The system corresponds to the instruction receiving, collaborative processing, transaction management and real-time synchronization modules. The present application solves the problem of data inconsistency and view asynchronization caused by information modification under multi-party collaboration, realizes flexible adjustment of logistics information, automatic recovery of business state and real-time consistency of multi-party view, and significantly improves the reliability and efficiency of supply chain collaboration.
