The invention discloses an efficient quayside container transfer method and system. The transfer method includes unshipping, evacuation of cargoes from a port, transition, entrance and shipping. The transfer system comprises more than one quay crane, a ferry crane and a stereoscopic transtainer, the quay cranes are arranged on a quayside rail a, the ferry crane is arranged below one sides, away from the shore line, of the quay cranes, and the stereoscopic transtainer is arranged on one side, away from the shore line, of the ferry crane. Compared with the prior art, the method and the system have the advantages that through the container transfer method, container loading, unloading and transition efficiency can be effectively improved, and production, manufacture and use cost of the container transfer system is lowered; the process of quick evacuation of the cargos from the port and port entrance of the containers can be realized through a quick channel; longitudinal transfer of the containers can be realized through automatic rail cars; besides, usage quantity of container trucks is reduced, and the problem that the container trucks easily jam on a container yard road is solved.
