Abstract：Marine environmental protection and marine economic development have received extensive attention from both academic and governmental sectors.This study explored the dynamic relationship between marine environmental efficiency and marine economic growth in China from both national and marine economic circle perspectives,using SBM model and PVAR model.The results showed that:(1)There was a more obvious dynamic relationship between marine environmental efficiency and eco-nomic growth.There were obvious synergistic effects between marine environmental efficiency and eco-nomic growth in the country and southern marine economic circle,and the two promote each other;there were more obvious negative responses between marine environmental efficiency and marine eco-nomic growth in the northern and eastern marine economic circle.(2)Both marine environmental effi-ciency and marine economic growth were characterized by vulnerability and were influenced by their own factors and external shocks.(3)Since the efficiency of China's marine environment was still at a low to medium level,the driving effect on the marine economy was not very obvious,so it is necessary to further promote the practice of marine environmental protection to realize the sustainable develop-ment of marine environment and marine economy.The relevant findings of this study can provide refer-ence for marine environmental protection and high-quality development of marine economy.
