内容概要：深海科技是指用于探索、研究和开发深海(通常指水深200米以下海域)的一系列科学技术及 装备体系，涵盖深海探测、资源开发、环境监测、生物研究等领域。海洋和太空一样深邃。随着陆地资 源不断枯竭，蕴藏丰富资源的深海日益成为保障国家资源安全、破解发展瓶颈的新战略空间。近年来， 我国海洋经济发展势头强劲，民生保障能力持续提高。初步估算，2025年上半年我国海洋经济生产总值 约5.1万亿元，同比增长约5.8%。深海科技是将潜在资源优势转化为现实生产力的关键，深海资源对经 济发展的潜在推动作用不可忽视。近十年来，中国深海科技的高速度发展不仅在国内空前，在国际也是 科技史上的奇迹。深海科技的发展推动了我国海洋经济的增长，深海能源开发、海洋生物医药、深海旅 游等新兴产业的兴起，为国家提供了更多的经济增长点。2025年我国深海科技市场规模约2.7万亿元， 预计2026年约为2.92万亿元。 上市企业：中国中车（601766）、中国船舶（600150）、中天科技（600522）、亚星锚链（601890）、 中集集团（02039）、海兰信（300065）、亨通光电（600487）、中船防务(600685.SH)、振华重工 ...
