Abstract: Offshore trade, as a new mode of trade with high added value in foreign trade activities, is imperative to promote the development of new forms of offshore trade when Hainan Free Trade Port is closed. Firstly, the concept, characteristics and types of offshore trade are systematically analyzed, and it is concluded that the improvement of offshore trade service system, the reduction of tax level, the relaxation of foreign exchange control and the establishment of financial market supervision system are important conditions for the continuous promotion of offshore trade development. Then, from the perspective of policy, and with reference to the successful experience of existing international free trade ports in developing offshore trade, the policy effect is visualized. Finally, it is suggested that Hainan Free Trade Port should pay more attention to the combination of offshore trade with the three goals of improving the government service level, optimizing the business environment and strengthening professional supervision, and should give priority to building an excellent integrated service platform for offshore trade. Centering on the design of tax system, the reform of foreign exchange management mode and the improvement of financial supervision, the policy framework should be established to speed up the development of offshore trade.
