智研咨询发布：海洋经济行业市场动态分析、发展方向及投资前景分析报告

Core Viewpoint - The marine economy in China is showing strong growth, with the total economic output expected to exceed 10 trillion yuan for the first time in 2024, reaching 10.5 trillion yuan, representing a year-on-year increase of 5.9% [2]. Industry Definition and Classification - The marine economy refers to the production activities that develop marine resources and rely on marine space, including marine fisheries, marine transportation, shipbuilding, salt production, marine oil and gas, and coastal tourism [4]. Industry Policies - Recent government policies aim to optimize the spatial layout of the marine economy, ensure ecological protection, and promote green transformation. For instance, the "Three-Year Action Plan for High-Quality Development of Marine Economy" (2024-2026) emphasizes green technology innovation and the establishment of low-carbon industrial parks [6][7]. - The "Guiding Opinions on Promoting the Large-Scale Utilization of Marine Energy" encourages provinces to focus on developing tidal, wave, and temperature difference energy as key tasks in marine economic development [7]. Development History - The development of the marine economy in China has gone through four stages since the founding of the People's Republic of China, evolving from a focus on political and military functions to a more comprehensive economic strategy that includes various marine industries [8]. Industry Barriers - Technical Barriers: New entrants face challenges due to the high technical requirements in deep-sea exploration and marine biotechnology, necessitating significant R&D investment [10][11]. - Financial Barriers: The capital-intensive nature of the marine economy creates high entry costs, with long investment return cycles making it difficult for new companies to secure funding [12]. - Market and Resource Barriers: The market is concentrated among leading firms, making it difficult for newcomers to compete and access quality marine resources [13]. Industry Chain - The marine economy's industry chain can be divided into upstream (marine equipment and materials manufacturing), midstream (marine fisheries, oil and gas, salt production, marine transportation, and coastal tourism), and downstream (marine product processing and retail) [14].
