| 摘要: |
| 文章基于2000—2019年中国11个沿海省（自治区、直辖市）的面板数据，实证分析了海洋产业结构升级对海洋全要素生产率的影响，并以海洋产业结构升级作为门槛变量，进一步研究海洋产业结构升级对海洋全要素生产率的非线性影响。结果说明，海洋产业结构升级对海洋全要素生产率有显著的正向作用；海洋产业结构升级在推动海洋全要素生产率提高的过程中存在一重门槛，随着海洋产业结构升级越过一重门槛，海洋产业结构升级对海洋全要素生产率的推动作用逐渐增大。根据研究结论，未来应加速推进涉海产业转型，鼓励海洋新兴产业发展，同时结合我国海洋产业发展现状，针对不同产业制定具体的对策。 |

| Abstract: |
| Based on the panel data of 11 coastal provinces in China from 2000 to 2019, this paper empirically examined the impact of marine industrial structure upgradation on marine total factor productivity, and established a panel threshold model which taking marine industrial structure upgradation as the threshold variable to investigate the nonlinear impact of marine industrial structure upgradation on marine total factor productivity. The results showed that marine industrial structure upgradation had a significant positive effect on the growth of marine total factor productivity, and the marine industrial structure upgradation had a heavy threshold in the process of promoting the improvement of marine total factor productivity, and as the marine industrial structure upgradation crossed a threshold, the marine industrial structure upgradation played an increasingly important role in promoting marine total factor productivity. According to the conclusions of the study, the transformation of sea-related industries should be accelerated, the development of marine emerging industries encouraged and at the same time the current situation of China's marine industry development should be combined to formulate specific countermeasures for different industries in the future. |
