Research on Contribution of China’s Marine Industrial Structure Change to Ocean Economic Growth base on Mathematical Model

The world is rich in marine resources. Lots of countries in the world are concerned about the hot topic of rational and effective development and utilization of marine resources, promoting the development of marine industry and realizing the growth of marine economy. This paper constructs the mathematical model of marine industrial structure and relative growth rate, calculates the contribution rate of 14 industrial structure changes to marine economic growth based on the national standard of China. The results show that the change of marine industry organization has a positive effect on marine economic growth, especially coastal tourism, marine scientific research and education service management industry Strong momentum.
