The ability to innovate in key areas has been continuously enhanced, and China's total marine economy exceeded 9 trillion yuan for the first time last year

According to the "statistical bulletin of China's marine economy in 2021" released by the Ministry of natural resources on the 6th, according to preliminary accounting, the National Marine GDP in 2021 was 9038.5 billion yuan, an increase of 8.3% over the previous year, accounting for 15.0% of the GDP of coastal areas, an increase of 0.1 percentage points over the previous year. Among them, the added value of the marine primary industry is 456.2 billion yuan, the added value of the secondary industry is 3018.8 billion yuan, and the added value of the tertiary industry is 5563.4 billion yuan, accounting for 5.0%, 33.4% and 61.6% of the marine GDP respectively.

Cui Xiaojian, deputy director of the National Marine Information Center, said that China's total marine economy will reach a new level in 2021, exceeding 9 trillion yuan for the first time. It is worth mentioning that the ability of scientific and technological innovation in the marine field has been continuously enhanced, and new breakthroughs have been made in technologies in key fields. Cui Xiaojian said that the scientific and technological innovation mechanism continued to deepen. Coastal areas adhere to the "two wheel" drive of marine scientific and technological innovation and institutional and mechanism innovation, and successively implement the system of "showing leadership" to stimulate the new vitality of marine scientific and technological forces. At the same time, we will increase diversified capital investment, support marine scientific and technological innovation and achievement transformation, and promote the high integration of marine industry talent chain, innovation chain and industrial chain. For example, Shandong initiated the establishment of marine community fund, focusing on supporting original innovation, transformation of marine achievements and cultivation of high-end marine science and technology industrialization projects; Guangdong continues to provide an annual special fund of 300 million yuan for marine economic development to support the collaborative innovation and agglomeration development of six industries: marine engineering equipment, offshore wind power, marine electronic information, natural gas hydrate, marine biology and marine public services.

In addition, scientific and technological achievements of independent innovation continue to emerge. Cui Xiaojian said that the research and development of high-end liquefied natural gas (LNG) equipment in China's marine gasification chain has been further improved, and the re delivery capacity of China's first LNG storage chain has been further increased by 170000 cubic meters; The anti typhoon floating offshore wind turbine independently developed and manufactured by China has been connected to the grid in Guangdong, and the construction of the first "offshore wind power + energy storage" offshore wind farm in China has entered the energy storage delivery period; The wave energy power generation devices "Zhoushan" and "Changshan" are being tested at sea. Ultra pure sodium alginate for in vivo implantation was registered with the drug evaluation center (CDE) of the State Drug Administration, breaking the international monopoly and realizing domestic production. The first set of shallow water underwater Christmas tree system independently developed by China was successfully tested in the Bohai Sea, ending the history of dependence on import of underwater Christmas tree system; A number of innovative marine economic technologies such as submarine high-voltage main base stations and submarine photoelectric composite cables have reached the international advanced level.
