Abstract: In the primary market for the right to use sea areas, the right to use sea areas is mainly sold through administrative examination and approval. Competitive methods account for a small proportion, and the role of the market is limited, resulting in unreasonable allocation of sea resources and low efficiency in the use of sea areas. Using this model can not solve the problem of the efficiency of marine resources allocation. On the basis of perfecting the administrative examination and approval system, we should distinguish between the public welfare sea and the commercial sea, set the conditions for the assignment of the right to use the sea area separately, and use the public welfare sea for assignment by administrative examination and approval to safeguard the public interest. Operating sea uses are sold by competitive means, with priority given to listing or auction, so as to improve the allocation efficiency of sea resources and promote the optimal allocation of sea resources.
