Shandong has a coastline of 3,345 kilometers, accounting for 1/6 of the country's total, with a sea area of 159,500 square kilometers and 589 islands. Its coastal resource abundance index ranks first in China.

Shandong's land area and sea area are comparable, and land and sea resources can be developed in a coordinated manner, which is a unique advantage.

The 2022 Report on the Work of the Shandong Provincial Government pointed out that it will unswervingly promote the construction of a strong marine province and create a strategic location for high-quality marine development. On the new journey, Shandong will continue to write three articles on "port, industry and ecology", focus on the coordinated development of land and sea resources, seek resources, wealth, and development from the sea, and tap the ocean for potential, quality, and efficiency.

Ports are basic and pivotal facilities and an important support for economic development. Of the nine provinces and regions along the Yellow River, Shandong, as the only eastern province along both the Yellow River and the coast, should makes full use of the important strategic resources and comparative advantages of ports to play an important role in the national strategy of the Yellow River, and build a new highland for opening up.

In terms of scientific research talents, Shandong has gathered nearly half of the country's marine scientific and technological talents and one-third of academicians in the marine field; in terms of industry, Shandong has the largest domestic ship power supplier Weichai Group, and Dongbao Heavy Industry, which fills the gap in the field of domestic civilian submersibles such as underwater intelligent platforms.

Shandong is at the forefront of marine biomedicine research and development. Set up the "China Blue Drug Depot Development Fund" with a total scale of 5 billion yuan, and create a marine drug manufacturing innovation center in Shandong Province; the "Blue Drug Depot" has built 6 product research and development platforms including modern marine drugs and modern marine traditional Chinese medicine.

In recent years, Yantai has implemented the blue bay renovation and restoration project and the beach cleaning action, and the proportion of the city's coastal waters with excellent water quality has reached 99.4%.

Rongcheng issued the first "Marine Carbon Sink Loan" in Shandong Province, providing a local enterprise with a loan of 20 million yuan to carry out kelp and wakame aquaculture and promote fishery carbon sink. Rongcheng has 100,000 mu of shallow sea multi-trophic aquaculture area, and the annual carbon sequestration is about 425,000 tons, equivalent to that of 70,000 hectares of forests for one year.
