Abstract: The 21st century is the century of marine, so the development of the marine economy has been an irresistible trend. As Fuqing is rich in marine natural resources and its marine culture is unique, there are certain advantages for Fuqing to develop marine economy. In recent years, Fuqing has achieved remarkable effects in developing marine economy, such as expanding the harbor industry rapidly, developing the fishery economy steadily, promoting the construction of industrial park orderly, etc. But the existing problems have restricted the sustainable development of marine economy in Fuqing, for example, the marine industrial structure needs further optimization, the marine scientific and technological contribution rate is lower, and there is an imbalance in the development and protection of ocean. In the future, Fuqing should optimize the marine industrial structure, enhance the marine scientific and technological innovation capability, and increase the protection for marine environment, thus to achieve the change from “big marine city” to “strong marine city”.
