Abstract: This paper used hierarchical analysis-entropy method combined with D-S evidence synthesis theory to determine the weights and establish an evaluation model to analyze the strength of marine resources development in the 11 coastal provinces from 2002 to 2015The results showed: China's overall development of marine resources increased from 0.199 in 2002 to 0.370 in 2015The distribution characteristics of the kernel density curve changed from“spike symmetry”distribution to“wide peak long tail”The spatial pattern of the development intensity of marine resources changed obviously, the provinces of high development intensity were from 0 in 2002 to 2 in 2015, and the region of low development intensity was reduced from 8 to 3, the space distribution was the highest in Tianjin and Hebei, followed by Jiangsu, other provinces development strength was lowThe development intensity of China's marine space resources showed that Tianjin, Hebei, Jiangsu, Shanghai were high, while Hainan and Fujian were lowThe exploitation intensity was far higher than that of other provinces in Tianjin and HebeiThe intensity of marine chemical resources development in all provinces was highThe development intensity of marine chemical resources in all provinces was highwith 6 provinces including Tianjin all above 0.75, and 3 provinces such as Jiangsu declining year by yearThe offshore aquaculture intensity was higher in Fujian, Guangdong, Guangxi,  Hainan, Shanghai was lower, and the offshore fishing intensity was in Hebei, Shandong, Jiangsu, Zhejiang, and Fujian were all higher,  with lower prices in Guangdong, Guangxi, and HainanThe level of economic development had a positive impact on the opening intensity of marine resourcesThe impact coefficient was 0.047, the impact coefficient of industrial structure level was 0.838, and the positive impact was obviousThe impact coefficient of social investment level on marine resources development industry was 228E-06It had a certain positive impact on the increase of the intensity of marine resources developmentThe level of human scientific research had a significant positive impact, the impact coefficient was 109764The impact coefficient of the openness level was- 0.0003,  the impact was small. The impact of government support the coefficient was-2.097, which had a large negative influence
