The index shows that in 2025, the China Ocean Economic Development Index was 128.8, an increase of 2.2% from the previous year. The marine economy has reached a new level, and the development benefits are improving. The scale and benefit index in 2025 was 128.1, an increase of 1.7% from the previous year. The national marine GDP reached 11 trillion yuan, an increase of 5.5% from the previous year. The number of marine economic activity units in key monitored marine industries increased by 6.2% from the previous year, and the vitality of operating entities continued to strengthen. The profit margin of operating income of key monitored marine industrial enterprises increased by 0.2 percentage points from the previous year, and the efficiency of enterprises continued to improve. The structure of the marine industry has been further optimized, and the ability for technological innovation has been continuously enhanced. The index for structural optimization and upgrading in 2025 was 133.8, an increase of 2.2% from the previous year. The value added of emerging marine industries increased by 7.3% from the previous year, and the proportion of marine GDP continued to rise. Investment in marine science and technology innovation has steadily increased, innovation achievements continue to emerge, breakthroughs have been made in the technology for hydrogen production from natural seawater electrolysis and magnesium co-production, and the independently developed world's largest 26 MW offshore wind turbine has successfully connected to the grid for power generation, with artificial intelligence models for the marine sector such as "Kanhai" successively released. The capability for development and utilization of marine resources continues to improve, and the level of resource conservation and intensive use is steadily increasing. The index for resource conservation and utilization in 2025 was 125.9, an increase of 1.9% from the previous year. In 2025, the total area of newly approved islands and sea areas in China amounted to 372,000 hectares, with investments exceeding 921.8 billion yuan, effectively ensuring the demand for islands and sea areas for projects in areas such as fisheries, oil and gas, and wind power. The production of marine crude oil and natural gas increased by 3.4% and 17.0% respectively from the previous year, and offshore wind power generation increased by 3.3% from the previous year. The scale of seawater resource utilization continues to expand, with daily production of seawater desalination projects exceeding 3 million tons. The marine sector's foreign trade has withstood pressure to achieve steady growth, and high-level opening up has achieved positive results. The index for foreign economic and trade in 2025 was 123.4, an increase of 1.7% from the previous year. The total value of goods traded in maritime imports and exports increased by 1.7% from the previous year, accounting for 61.5% of the total trade volume. The throughput of foreign trade goods at coastal ports increased by 4.7% from the previous year. In terms of compensated gross tonnage, the proportion of China's completed maritime exports to the global total increased by 0.5 percentage points from the previous year. The marine ecological environment continues to improve, and livelihoods are effectively guaranteed and improved. The index for people's livelihood security and improvement in 2025 was 132.0, an increase of 3.7% from the previous year. The proportion of nearshore marine areas with good water quality (Class I and II) was 84.9%, an increase of 1.2 percentage points from the previous year. The per capita possession of marine products increased by 1.0 kilograms from the previous year. The marine tourism market is booming, with island tours, cruise tours, and water sports becoming new hotspots. This index is a comprehensive quantitative assessment of the development of China's marine economy over a certain period of time, covering main areas such as development scale and benefits, structural optimization and upgrading, resource conservation and utilization, foreign economic and trade, and livelihood security and improvement. The index is based on 2015 as the base year, with a base index value of 100. This article is compiled from the Ministry of Natural Resources, edited by GMTEight: Chen Wenfang.
