Core Viewpoint - The report highlights deep-sea technology as a new national strategic industry, emphasizing its importance for resource and national defense security, and its potential to explore the "blue" economy [1][2]. Resource Security - The urgency for China to secure deep-sea resources is underscored, as the U.S. and Japan are accelerating their deep-sea mining efforts. The U.S. has initiated policies to expedite mineral resource development in international seabed areas, while Japan plans to drill for rare earths at a depth of 5,500 meters by 2026 to reduce reliance on China. China's dependency on foreign resources is significant, with over 70% for oil and natural gas, and 78%-95% for strategic minerals like copper, cobalt, and nickel, making deep-sea resources crucial for national security [2]. National Defense Security - The report discusses the need for China to address its "open underwater national gate" security dilemma. The deep sea offers significant advantages for military operations, and establishing a robust deep-sea combat system is essential for implementing a "deep denial" strategy. The U.S. and Japan are actively developing their deep-sea military strategies, while China must enhance its underwater defense capabilities to secure its maritime interests [3]. Blue Economy - The marine economy in China reached a production value of 10.54 trillion yuan in 2024, indicating a substantial market potential. Future growth in the marine economy is expected to be driven by emerging sectors such as offshore fishing, offshore wind power, port shipping, and seawater desalination, alongside improvements in deep-sea technology productivity driven by security needs [3][4]. Deep-Sea Technology Industry Chain - The deep-sea technology industry chain encompasses basic materials to high-end equipment manufacturing, focusing on three core areas: deep diving, deep drilling, and deep networking. Key materials include titanium alloys for deep-sea pressure structures, sonar systems for underwater detection and navigation, and underwater robots for exploration and resource development [4][5]. Investment Recommendations - The report suggests focusing on "situation awareness" capabilities as a foundational aspect of deep-sea development. Companies such as China Marine Defense, Jizhi Co., and Zhongke Haixun are recommended for investment in the initial phase, as they are pivotal in enhancing situational awareness in deep-sea technology [5].
