The development of marine culture industry is closely related to the prominence of marine economy and rising of marine culture status in the ocean century. Till now it has become an economic, social and cultural growth force, demonstrating huge development potentials. The Yangtze River Delta Region, one of the most vigorous economic areas in China today, abounds in rich marine culture resources and profound cultural deposits. In the future modernization process of the region, sustainable economic development should be maintained; simultaneously, a transformation should be made from the exploitation of increasingly sterile land resources to abundant ocean resources, and ocean culture industry should be attached much importance. The city of Nantong, which lies in the Delta region, has drawn upon the marine advantage and promoted the interaction of ocean culture and economic activities; accordingly, in the city, the ocean culture industry has been emerging and thriving. Nantong’s development of ocean culture industry attributes a lot to its designed and operated systems and institutions, such as linkage of rivers and the sea, scientific planning, innovative mechanism, etc. and the development ideas of exploring and upholding the local humanist spirits. This also strategically provides referential paths and strategies for development of the marine culture industry of the whole Yangtze River Delta Region.
