| The ocean is the basic environment of people, and their important resource. As the land and energy are increasingly scarce, the development of marine economy has been an important way of expanding the space for future and meanwhile, alse breaking the bottleneck of resource shortage. Ningbo is the core of Zhejiang marine economic development demonstration area, and plays an important role in Zhejiang, and even China’s marine economy. Ningbo has obvious advantage, but also faces the disadvantages. Meanwhile, it also faces the competition of other coastal cities. For Ningbo, how to resolve its own problems and keep its advantages in the fierce competition is a task of top priority.Against such a backdrop, the thesis integrates theory with practice and makes qualitative as well as quantitative analysis, in order to learn how to optimize marine industrial structure and spatial distribution, in order to enforce Ningbo complete the strategic changes from big marine economic city to strong one. From the analysis, we can see that marine industry of Ningbo develops rapidly and has great potential. It grows year by year and keeps15-20%of GDP. But the industrial structure needs to be adjusted. The second industry makes the biggest proportion and plays the biggest role in the economic growth, which is not good for the structure. The progress of optimization is also slow. On this basis, the paper proposes the guiding ideology and targets of Ningbo’s marine industry structure optimization. Meanwhile, it makes the suggestions that we should optimize the spatial distribution, adjust the industry structure, innovate the management, strength the service and support, raise the level of science and technology, optimize marine ecological environment and so on.. |
