Since the 13th Five-Year Plan for National Marine Economic Development proposed “promote Shenzhen，Shanghai and other cities to build global ocean central cities”，the seven cities of Dalian，Tianjin，Qingdao，Ningbo，Zhoushan，Xiamen，and Guangzhou have also proposed construction for the goal of the global ocean center city，various provinces have actively promulgated relevant policies and formulated a series of development measures for the construction of ocean economy，scientific and educational innovation development，ecological civilization construction，international influence，management service level，etc. However，due to the fact that the global ocean center city in China is still in the construction exploration and initial stage.
