| 为应对海洋经济增长动能不足、海洋产业结构同构化矛盾，响应“引进来”与“走出去”相结合的政策号召，提升海洋产业结构转型升级的质量和效率，文章基于沿海11地区2007—2019年的面板数据，采用双重差分模型（DID）对“一带一路”倡议启动前后的海洋产业结构转型升级水平进行量化评估，并进行异质性检验。结果表明：“一带一路”倡议显著促进海洋产业结构的转型升级，并且存在区域异质性差异，长三角和珠三角地区的海洋产业结构转型升级较为明显；对外直接投资对海洋产业转型升级的促进作用较为显著；受限于技术溢出和资本积累的滞后效应，外商直接投资的影响并不明显。据此提出，中国应依托“一带一路”倡议，积极推进对外直接投资，提高海洋科技创新能力，充分发挥区域优势，构建多元化的开放型海洋产业体系。 |

| Abstract: |
| In response to the lack of driving force for the growth of the marine economy and the problem of the homogeneous structure of the marine industry, and responding to the policy call of combining “bringing in” and “going global”, so as to improve the quality and efficiency of transformation and upgrading, this paper adopted the difference-in-difference model (DID) to quantitatively evaluate the transformation and upgrading level of marine industrial structure before and after the launch of the Belt and Road Initiative, and conducted heterogeneity test, based on the panel data of 11 coastal provinces and municipalities from 2007 to 2019. The results showed that: The Belt and Road Initiative had significantly promoted the transformation and upgrading of marine industrial structure, and there were regional heterogeneity differences. The transformation and upgrading of marine industrial structure in the Yangtze River Delta and Pearl River Delta were more obvious. FDI had played a significant role in promoting the transformation and upgrading of marine industry. Limited by the lag effect of technology spillover and capital accumulation, the influence of foreign direct investment was not obvious. Therefore, it was proposed that China should rely on the Belt and Road Initiative, actively promote foreign direct investment, improve the innovation capacity of marine science and technology, give full play to regional advantages, and build a diversified open marine industry system. |
