This paper points out that the existing marine administrative system in China doesn′t operate efficiently, because of lack of highlevel coordination organization,coordination mechanism; information sharing mechanisms etc. To improve our marine management system requires the establishment of comprehensive marine coordination mechanisms. The United States and Japan that have two different marine management systems attach great importance to the construction of coordination mechanisms. So,on the basis of our existing systems, to achieve the coordination of the marine integrated management and improve marine management system in our country′s, we should learn from the overseas construction experience, propose the specific recommendations of coordination mechanism for our country′s marine management: establish and improve many searelated cooperation agencies, consulting and staff agencies; build a comprehensive marine coordination organizational model chart and complete the construction of marine management information system,and build an effective platform of communication for each searelated management department.
