In recent years, major maritime countries and international organizations such as the United States, Russia, Japan, South Korea, the United Nations, and the European Union have issued multiple medium − and long−term ocean strategies and plans, intensifying efforts to promote the development of key marine science and technology fields, striving to make breakthroughs and progress in marine basic research, deep−sea technology, Arctic technology, shipping industry, marine renewable energy, and marine electronic information technology. In the medium to long term, the world's marine technology will present many new development trends. From the perspective of planning issued by major developed countries and international organizations involved in the ocean, this article summarizes and analyzes the main trends in the development of world ocean technology in areas such as ocean basic research, deep−sea fields, shipping industry, marine renewable energy development, and global ocean observation. It also summarizes that there are still many shortcomings in China's ocean technology, such as the gap between its basic research level and that of a world ocean technology powerhouse, insufficient innovation in deep−sea technology equipment, and reliance on imports for key core technologies. On this basis, it is suggested to strengthen the basic research of marine science and technology, and enhance the research and development efforts in key marine technology fields.
