The primary driving forces for Guangdong,Shanghai,Shandong and Zhejiang leading other coastal areas are openness,efficiency,innovation and sustainability respectively;(2) The temporal differentiation of China’s regional marine economy shows a dynamic evolution process of obvious in early stage, alleviating in middle stage and balance in later stage;(3) The spatial zoning types and high-quality development paths of 11 coastal provinces are determined based on spatial differentiation:Shanghai and Zhejiang are high-value congregate types and named as demonstration regions,which should build global marine center cities with deepening regional cooperation and high-standard opening-up;Shandong and Guangdong are high-value discrete types and named as key engine regions,which should enhance the international competitiveness of marine industry with scientific and technological innovation;Tianjin,Hebei and Liaoning are low-value congregate types and named as potential zooming regions,which should improve the efficiency of marine resources utilization with regional cooperation;Jiangsu,Fujian,Hainan and Guangxi are low-value discrete types and named as land-sea coordination regions,which should build modern and characteristic marine industrial system with coordinated land and sea.
