To explore the impact of different policies and combined policies on the construction effect of maritime power, this paper designs three types of 16 policy situations from the aspects of fertility, science and technology, economy, environment and education. Then a system dynamics model for the construction of maritime power is constructed to simulate the policy. The results shows that under the current policy model the construction level of China's marine power can be con-tinuously improved and that both indicators of economic strength and ecological governance have the largest increase. In the case of a single policy, fertility policy cannot improve the construction level of marine power while economic policy or education policy can only promote the improvement of some indicators. Science and technology policy has a significant effect on early promotion of indicators in each sector and is surpassed by education policy in the later period. In the case of combined policies, if economic strength, technological competitiveness and resource utilization efficiency are concerned, then policy combination of science and technology and education should be selected. It is better to choose policy combination of environment and education when considering the effect of ecological governance and sea area management. For rapid development and utilization of sea areas the policy mix of economy and education should be selected. Finally, education policy plays an important role in achieving different goals of the marine power construction.
