Since the 21st century, rapid development of marine economies has contributed considerably to economic growth. The problem of coordinated development of marine ecological environmental protection and economies have become increasingly prominent. This study establishes a set of index evaluation systems for coordinated development of marine ecology and economies and uses the Analytic Hierarchy Process to analyze the coordination of marine ecology and marine economic development in China. The results show that more attention has been paid to the protection of marine ecological environment during marine economic development in China since the year 2012; Furthermore, the coordination of marine economic development and marine ecological protection in coastal provinces was analyzed. Results show that Shanghai and Shandong Province better coordinate marine economic development and marine ecological protection in 2016. The results of the index evaluation system suggest that China marine ecological protection should further increase the protection of marine ecological environments by preventing and controlling marine pollution and carrying out ecological restoration.
