科技创新对海洋经济增长的影响与传导机制研究

文章基于2009—2018年沿海11个省（自治区、直辖市）的面板数据，借助面板联立方程模型使用三阶段最小二乘法实证考察海洋科技创新对海洋经济增长的影响与传导机制。研究结果表明：（1）海洋科技创新对海洋经济增长的影响具有双重路径，海洋科技创新不仅可以直接促进海洋经济增长，还可以通过海洋产业结构升级间接影响海洋经济增长；（2）东部和南部海洋经济圈的海洋科技创新与产业结构升级显著促进海洋经济增长，而北部海洋经济圈的海洋科技创新对海洋经济增长的影响不显著；（3）人力资本对海洋经济增长具有显著促进作用，且对北部海洋经济圈的促进作用更强。未来应进一步提升人力资本质量，完善海洋科技创新体系，加快创新成果转化，促进海洋产业结构合理升级。

Research on the Influence and Transmission Mechanism of Scientific and Technological Innovation on Marine Economic Growth

Based on the panel data of 11 coastal provinces (autonomous regions and municipalities) from 2009 to 2018, this paper used the panel simultaneous equation model to empirically investigate the impact and transmission mechanism of marine technological innovation on marine economic growth using the three-stage least squares method. The research results showed that: (1) The impact of marine scientific and technological innovation on marine economic growth had dual paths. Marine scientific and technological innovation could not only directly promote marine economic growth, but also indirectly affect marine economic growth through the upgrading of marine industrial structure; (2) Eastern and southern marine science and technology innovation and industrial structure upgrading in the marine economic circle significantly promoted marine economic growth, while marine technological innovation in the northern marine economic circle had no significant impact on marine economic growth; (3) Human capital had played a significant role in promoting marine economic growth, and the promotion effect on the northern marine economic circle was stronger. In the future, the quality of human capital should be further improved, the marine science and technology innovation system should be improved, the transformation of innovation achievements should be accelerated, and the rational upgrade of the marine industrial structure should be promoted.
