en.Wedoany.com Reported - To objectively reflect the development of China's marine economy, the National Marine Data and Information Service has compiled the 2026 China Marine Economic Development Index. This index provides a comprehensive quantitative assessment of China's marine economic development over a specific period, covering key areas such as development scale and efficiency, structural optimization and upgrading, resource conservation and utilization, foreign economy and trade, and livelihood security and improvement. The index uses 2015 as the base year, with a base value of 100.

The index shows that in 2025, China's Marine Economic Development Index stood at 128.8, an increase of 2.2% year-on-year. The marine economy is progressing towards innovation and quality, achieving new results in high-quality development, characterized by the following features:

First, the scale of the marine economy has reached a new level, with development efficiency recovering and improving. In 2025, the development scale and efficiency index was 128.1, up 1.7% year-on-year. The national gross ocean product reached 11 trillion yuan, an increase of 5.5% year-on-year. The number of marine economic activity units in key monitored marine industries grew by 6.2% year-on-year, indicating continuously enhanced vitality of business entities. The operating income profit margin of key monitored marine industrial enterprises increased by 0.2 percentage points year-on-year, with sustained improvement in corporate efficiency.

Second, the marine industrial structure has been further optimized, with continuously enhanced technological innovation capabilities. In 2025, the structural optimization and upgrading index was 133.8, up 2.2% year-on-year. The added value of emerging marine industries increased by 7.3% year-on-year, with a rising share in the gross ocean product. Investment in marine science and technology innovation steadily increased, with a continuous stream of innovative achievements. Breakthroughs were made in the co-production technology of hydrogen and magnesium through direct electrolysis of natural seawater, the world's largest self-developed 26-megawatt offshore wind turbine was successfully connected to the grid, and marine-focused artificial intelligence large models such as "Kanhai" were successively released.

Third, the capacity for marine resource development and utilization has continuously improved, with steady enhancement in resource conservation and intensive utilization. In 2025, the resource conservation and utilization index was 125.9, up 1.9% year-on-year. In 2025, the newly approved area for sea and island use nationwide was 372,000 hectares, involving an investment of over 921.8 billion yuan, effectively supporting the demand for sea and island use in sectors such as fisheries, oil and gas, and wind power. The output of marine crude oil and natural gas increased by 3.4% and 17.0% year-on-year, respectively, while offshore wind power generation grew by 3.3% year-on-year. The scale of seawater resource utilization continued to expand, with the daily production capacity of seawater desalination projects exceeding 3 million tons.

Fourth, foreign trade in the marine sector achieved steady growth despite pressure, with high-level opening-up yielding positive results. In 2025, the foreign economy and trade index was 123.4, up 1.7% year-on-year. The total import and export volume of goods transported by sea increased by 1.7% year-on-year, accounting for 61.5% of the total import and export volume. The throughput of foreign trade cargo at coastal ports increased by 4.7% year-on-year. Measured in compensated gross tonnage, the completion volume of China's exported seagoing vessels accounted for a share of global seagoing vessel completions that increased by 0.5 percentage points year-on-year.

Fifth, the marine ecological environment has continuously improved, with effective and robust livelihood security and improvement. In 2025, the livelihood security and improvement index was 132.0, up 3.7% year-on-year. The proportion of coastal waters with excellent or good water quality (Class I and II) was 84.9%, an increase of 1.2 percentage points year-on-year. The per capita possession of marine aquatic products increased by 1.0 kilogram year-on-year. The marine tourism market saw high enthusiasm, with island tourism, cruise tourism, and marine sports becoming new hotspots.
