Shanwei's economy has traditionally been based on fishing and agriculture. The city's long coastline supports a significant fishing industry, producing a wide variety of seafood for domestic consumption and export.
In recent years, Shanwei has been developing its manufacturing sector, particularly in electronics, textiles, and food processing. Tourism is a growing industry, driven by Red Bay's popularity as a coastal destination. The city is also investing in port infrastructure and logistics to support regional trade. Despite being less developed than other Pearl River Delta cities, Shanwei benefits from improving transportation links and government support for the eastern Guangdong region.
