“启运港退税政策”、“保税港区政策”以及“属地申报、口岸验放”通关模式都是发展港口经济的刺激政策。通过对上述政策的预期目标、评估标准和政策实施效果进行分析后发现,相关政策叠加后的实际效应有正有负。三项政策叠加实施后能够给出口企业带来效益提升,但港口间的恶性竞争补贴外国消费者问题以及政策成本和政策抵消问题,尤其应当受到关注。 “Port Refund Policy ”, “Bonded Port Area Policy ” and “territory declaration, port clearance ” customs clearance mode are the development of port economy stimulus. After analyzing the expected targets, evaluation criteria and the implementation of the above policies, it is found that the actual effects of the related policies are positive and negative. The implementation of the three policies can bring benefits to export enterprises. However, the vicious competition among ports should pay particular attention to foreign consumers and the problems of policy costs and policy offsetting.
