深海科技｜石华海月揽蛟龙，万亿深海孕生机

Core Viewpoint - Deep-sea technology has been included in the government work report for the first time during the 2025 "Two Sessions," indicating the high-level leadership's emphasis on deep-sea development. This sector is expected to receive supportive policies from local governments, similar to the development opportunities seen in low-altitude economy and commercial aerospace [1][2]. Policy Support and Development - The government work report emphasizes the promotion of deep-sea technology alongside commercial aerospace and low-altitude economy, highlighting its political, economic, technological, and military significance. The national marine production value is projected to exceed 10 trillion yuan in 2024, reaching 105.438 billion yuan, with a year-on-year growth of 5.9% [2][5]. - Local governments in coastal areas are anticipated to introduce related stimulus policies to support the development of deep-sea technology as a new productive force [2][5]. Key Policies - The "Shanghai Marine Industry Development Plan (2025-2035)" aims to promote high-quality development of the marine economy, focusing on deep-sea technology and marine observation network construction [5]. - The central government has established a 50 billion yuan fund to support deep-sea exploration, equipment manufacturing, and resource development [5]. - Various provinces are developing their marine industry frameworks, emphasizing deep-sea resource development, marine biotechnology, and high-end marine equipment manufacturing [6]. Development Pathways - The development of deep-sea technology focuses on three key areas: deep diving, deep drilling, and deep networking. High-performance manned and unmanned submersibles are becoming a priority for many countries, with China advancing significantly in deep-sea exploration [7][24]. - The deep-sea sector is characterized by high pressure and corrosion, making materials like titanium and carbon fiber composites essential for equipment development [13][14]. Investment Opportunities - Investment should prioritize core manufacturers across the deep-sea technology supply chain, particularly in deep-sea equipment, deep-sea information technology, and upstream materials [24][26]. - The demand for underwater communication technologies is expected to grow, with a shift towards multi-modal communication methods to meet various operational needs [13][19].
