Shipping finance service plays a significant role in developing a city to become an international shipping and financial center. Based on the experiences gained from other countries，the relationship between building a shipping center and developing shipping finance industry is very close. Take London as an example. As a long-standing international shipping center，London takes the advantages of its developed financial industry to keep its competitive edge in the world. In recent years，alongside with the development of shipping industry，Guangzhou has made a real achievement in shipping finance. Nevertheless，there is a big gap between Guangzhou and other shipping centers over legal environment，shipping finance scales and others. It becomes the most challenging problem to develop the shipping finance industry of Nan Sha Free Trade Zone in order to accumulate high-end elements of shipping service.
