Abstract
At present, China's marine energy industry is still in its infancy, but there is no doubt that the development of this industry will help China to achieve sustainable development. Therefore, effective policies are needed to promote the industrialization of the industry as soon as possible. This paper systematically consulted the relevant information on the research and development of marine renewable energy, focusing on China's marine energy industry policy, including the national energy strategy, the progress of China's marine energy policy, technology policy, market policy and other related content, emphasizing the importance of marine energy policy in promoting the development of marine energy industry. Finally, in view of the deficiencies in the development of marine energy industry in China, the corresponding improvement strategies are put forward.
