| 近年来，我国海洋经济得到快速发展，但由于各区域海洋产业基础不同，要素投入的数量和方式也存在差异，尤其是海洋科技创新能力与效率还有极大的提升空间。文章借助熵权TOPSIS法和三阶段DEA模型分别测量沿海区域海洋科技创新的能力及效率，并总结时空差异特征，进而运用Tobit模型和灰色关联法分析形成差异的影响因素。结果显示：沿海区域海洋科技创新能力呈现“下降-上升-下降”趋势，其中北部湾区域海洋科技创新能力与珠三角、长三角区域相比存在明显差距；五大区域海洋科技创新综合效率排名由高到低依次为珠三角、环渤海、长三角、海峡西岸、北部湾；海洋产业结构高度化指数对海洋科技创新发展水平的影响最大，对海洋基础设施建设水平的影响最弱，且不同区域海洋科技投入对海洋科技创新发展水平的贡献程度存在差异。建议以实现海洋产业结构的优化与升级为目标，调整海洋科技投入结构，加快海洋科研人才队伍建设，进一步改善海洋科技创新的生态环境以提升海洋科技创新能力与效率。 |

| Abstract: |
| In recent years, China′s marine economy has developed rapidly, but due to the different basis of marine industry in various regions, the quantity and mode of factor investment are also different, especially the ability and efficiency of marine scientific and technological innovation still have great room for improvement. With the help of Entropy TOPSIS method and Three-stage DEA model, this paper measured the ability and efficiency of marine scientific and technological innovation in coastal areas, summarized the characteristics of temporal and spatial differences, and then used Tobit model and grey correlation method to analyze the influencing factors of differences. The results showed that: ① the marine scientific and technological innovation ability of coastal areas showed a “decline-rise-decline” trend. Among them, there was an obvious gap between the marine scientific and technological innovation ability of Beibu Gulf region and the Pearl River Delta and Yangtze River Delta. ② The comprehensive efficiency of marine scientific and technological innovation in the five regions was ranked as Pearl River Delta > Bohai Rim > Yangtze River Delta > West Bank of the Strait > Beibu Gulf. ③ The upgrading index of marine industrial structure had the greatest impact on the development level of marine science and technology innovation, and the impact of marine infrastructure construction was the weakest. There were differences in the contribution of marine science and technology investment to the development level of marine science and technology innovation in different regions. It was suggested to adjust the investment structure of marine science and technology, speed up the construction of marine scientific research talent team, and further improve the ecological environment of marine scientific and technological innovation, so as to improve the ability and efficiency of marine scientific and technological innovation. |
