China's marine scientific and technological innovation is entering the fast track. New breakthroughs in marine technology and equipment have promoted the rapid development of marine industries such as marine energy, marine medicine, and marine oil and gas, and opened up a new blue economic space. As the pace of industry towards modernization, greenness, and wisdom continues to accelerate, the content of China's marine economy has become richer. It should also be noted that China's marine economic development is still facing quite a few challenges, such as some key core technologies that need to be broken through urgently, and some key equipment is still dependent on imports. To further advance marine development into depth and breadth, it is necessary to accelerate the development of new marine productivity, comprehensively improve the efficiency of marine resource utilization, and continuously open up new tracks and shape new advantages on the premise of securing ecological safety boundaries. To advance into the ocean, we must focus on implementing the “science and technology to develop the sea” strategy and strive to break through the scientific and technological bottlenecks that limit the protection of the marine ecological environment and the high-quality development of the marine economy. By focusing on independent research and development of key technologies, further increasing R&D investment and talent cultivation, promoting the transformation of ocean development methods to recycling, and striving to build a harmonious marine ecological environment with people and seas, there is a solid foundation for the sustainable development of the marine economy.
