By industry:

Traditional marine industries maintained steady and relatively fast development. The supply capacity of marine aquatic products continued to strengthen, with diversified sales channels such as e-commerce livestreaming and rapid delivery services accelerating their deployment. The supply security capacity of offshore oil and gas resources continued to improve, with offshore crude oil and natural gas production increasing by 3.4% and 17.0% year-on-year, respectively. Marine engineering and construction developed steadily, with significant achievements in intelligent and green projects for maritime transportation infrastructure. The marine shipbuilding industry continued its rapid growth, maintaining a leading global market share in new orders, ship completions, and order backlogs for seagoing vessels, with notable progress in green, low-carbon, large-scale, and high-end development. The marine chemical industry grew relatively fast, with major chemicals showing a trend of increased volume and decreased prices. Marine transportation maintained steady and relatively fast growth, with marine freight volume and cargo turnover increasing by 5.1% and 6.8% year-on-year, respectively.
