| 探究海水产品流通现代化作用于海洋碳汇渔业生态效率的内在机制与实际成效，对海洋碳汇渔业实现高质量发展具有重要意义。文章从商流效率、物流效率和信息流效率 3 个维度，结合技术推广强度的中介效应及水产品贸易、工业化水平的门槛效应，分析其影响机制与效果。结果表明：（1）海水产品流通现代化对海洋碳汇渔业生态效率具有显著的直接促进效应，整体上提升了海洋碳汇渔业生态效率。（2）在技术推广强度的中介作用下，海水产品流通现代化通过商流、物流和信息流效率升级，降低低碳技术采纳门槛与推广成本，间接提升生态效率。（3）在水产品 贸易水平和工业化水平的门槛约束下，海水产品流通现代化与海洋碳汇渔业生态效率之间存在非 线性关系，当二者处于较低水平时，流通现代化的促进作用更强，超过门槛值后边际效应递减。因此，应推进海水产品流通体系现代化建设，强化水产低碳技术推广与区域协同，实施差异化的 流通升级与生态效率提升政策，助力海洋碳汇渔业生态效率提升与可持续发展。 |

| Abstract: |
| Exploring the internal mechanism and practical effects of the modernization of seafood circulation on the ecological efficiency of marine carbon sink fisheries is of great significance for the high-quality development of marine carbon sink fisheries．From the three dimensions of commodity circulation efficiency，logistics efficiency，and information flow efficiency，this paper analyzes the impact mechanism and effects by combining the mediating effect of technology promotion intensity and the threshold effect of aquatic product trade level and industrialization level． The results show that：（1）The modernization of seafood circulation has a significant direct promoting effect on the ecological efficiency of marine carbon sink fisheries，and improves the ecological efficiency of marine carbon sink fisheries overall．（2）Under the mediating effect of technology promotion intensity，the modernization of seafood circulation indirectly improves ecological efficiency by upgrading the efficiency of commodity circulation，logistics， and information flow，which reduces the threshold for adopting low-carbon technologies and the cost of technology promotion．（3）Under the threshold constraints of aquatic product trade level and industrialization level，there is a non-linear relationship between the modernization of seafood circulation and the ecological efficiency of marine carbon sink fisheries．When both levels are relatively low，the promoting effect of circulation modernization is stronger，and the marginal effect decreases after exceeding the threshold value．Therefore，it is necessary to promote the modernization of the seafood circulation system，strengthen the promotion of low-carbon aquatic technologies and regional coordination，and implement differentiated policies for circulation upgrading and ecological efficiency improvement，so as to contribute to the improvement of ecological efficiency and sustainable development of marine carbon sink fisheries． |
