Zhoushan in Zhejiang province has made significant strides in transforming itself into a modern maritime city over the past few years.

The city has implemented proactive measures to bolster its marine economy, achieved breakthroughs in institutional innovation, and accelerated integrated urban-rural development.

Zhoushan's marine economy has experienced substantial growth, contributing to 68.5 percent of the city's GDP in 2023. Notably, the Zhoushan Green Petrochemical Base stands as the largest in the country, boasting an annual refining capacity of 40 million metric tons, along with annual production capacities of 11.8 million tons of aromatics and 4.2 million tons of ethylene. Additionally, the shipbuilding industry has seen robust expansion, with Zhoushan currently possessing the capacity to build 7 million deadweight tons of ships annually and repair over 3,000 vessels of over 10,000 tons each year.

Furthermore, the Zhoushan National Pelagic Fishery Base has emerged as a comprehensive hub integrating transoceanic seafood transit, electronic trading markets, financial support services, and cold chain processing. In 2023, the total output value of the entire industrial chain in the city exceeded 100 billion yuan ($13.96 billion).

In 2017, the establishment of the China (Zhejiang) Pilot Free Trade Zone in the city marked Zhoushan's entry into the free trade zone era, significantly elevating the city's level of openness.

The city has accumulated 269 distinctive institutional innovation achievements and practical cases, with 125 being the first of their kind in the country and 32 being replicated and promoted nationwide.

In July 2021, Zhoushan proposed to promote the integrated development of urban and rural areas while continuously upgrading public transportation facilities and infrastructure on remote islands.

The water diversion project successfully resolved long-standing water supply issues on all 86 inhabited islands.
