Abstract：This study，based on data from the China Marine Economic Statistical Bulletin（20o5-2024）and other sources，employs multiple linear regression and the Sustainable Development Index（SDI） model to analyze thedevelopment characteristics and benefitsofChina’s major marine industries from the three dimensions of economy，resources，and environment.The research shows that： over the past 2O years，industrial added value has increased from 720.2 billion yuan to 4 373.3 billion yuan（with an average annual growth rate of 9.4% ）， and the tertiary industry structure has optimized from 17.0：31.0：52.0 to 4.7：35.8：59.5 ，demonstrating phased characteristics of“high-speed growth-structural adjustment-resilience recovery”. The cumulative newly added sea use area is 4.573 milion hectares，the efficiency of unit sea use has increased to 166.285 billion yuan/million hectares，and the area of excellent marine water quality has increased by 31.2% ．The results of multiple linearregresionshow that theareaofexcellentmarine waterqualityhasasignificantpositive impactonindustrialadded value （ β=0.8197 P<0.05 ），while the impact of the newly added sea use area is not significant.The SDI index has increased from0.30 to 0.59，and under the policy-driven effct after2015，theresource eficiencyand ecological quality have achieved coordinated improvement. The study proposes to promote the green transformation of industries，strengthen the control of sea use eficiency，and construct an ecological value conversion mechanism to achieve the high-quality and sustainable development of marine industries.
