| 新质生产力以突破性创新技术为基础，推进海洋技术创新，加速海洋传统产业转型升级，增强海洋产业链韧性。文章基于2008—2022年我国11个沿海省（自治区、直辖市）的面板数据，运用固定效应模型和中介效应模型探究新质生产力对海洋产业链韧性的影响机理以及海洋技术创新的中介效应。研究发现：新质生产力可显著提高海洋产业链韧性，该结论经过稳健性检验和内生性检验后仍然成立。区域异质性检验表明，南部海洋经济圈新质生产力对海洋产业链韧性的促进作用高于北部海洋经济圈和东部海洋经济圈；时间异质性检验表明，2015—2022年新质生产力对海洋产业链韧性的促进作用高于2008—2014年。新质生产力可通过海洋技术创新提高海洋产业链韧性。因此，应充分发挥新质生产力新动能，加大海洋技术创新投入，因地制宜提高海洋产业链韧性。 |

| Abstract: |
| The new quality productive forces are based on breakthrough innovative technologies, promoting marine technological innovation, accelerating the transformation and upgrading of traditional marine industries, and enhancing the resilience of the marine industry chain. On the basis of panel data of 11 coastal provinces (autonomous regions、centrally administered municipalities) in China from 2008 to 2022, the article uses fixed effect and mediation effect econometric models to explore the mechanism of the impact of new quality productive forces on the resilience of the marine industry chain and the mediation effect of marine technological innovation. The study shows that the new quality productive forces can remarkably improve the resilience of the marine industry chain, and this conclusion remains valid even after the robustness test and the endogeneity test. The regional heterogeneity test indicates that the promotion effect of new quality productive forces on the resilience of the marine industry chain is higher in the Southern Ocean Economy Circle than in the Northern Ocean Economy Circle and the Eastern Ocean Economy Circle. Temporal heterogeneity test shows that new quality productive forces contributed more to the resilience of the marine industry chain in 2015-2022 than in 2008-2014. New quality productive forces can improve the resilience of the marine industry chain through marine technology innovation. Therefore, it is necessary to give full play to the new drivers of new quality productivity, increase investment in marine technology innovation, and enhance the resilience of the marine industry chain according to local conditions. |
