碳达峰碳中和目标下海水养殖业绿色转型的现实困境与推进路径——以大连市为例

Realistic Dilemmas and Promotion Paths of Green Transformation in Mariculture under the Carbon Peak and Carbon Neutrality Goals—A Case Study of Dalian

摘要: 推动海水养殖业绿色低碳转型，对于实现碳达峰碳中和目标、促进渔业可持续发展具有重要价值。本文以大连市海水养殖业为研究案例，采用文献分析与案例研究相结合的方法，在系统梳理国内外海水养殖碳排放与绿色转型研究进展的基础上，分析当前大连海水养殖业绿色转型面临的现实困境，探讨推进转型的具体路径。研究发现，养殖模式粗放与碳核算缺失、低碳技术供给推广不足、养殖主体动力欠缺、政策激励约束不健全是转型面临的主要障碍。引入路径依赖理论分析表明，上述困境之间存在自我强化机制，形成了阻碍转型的“锁定”状态。破解困局需从碳汇渔业布局、技术推广体系、主体能力建设和政策制度完善等方面协同发力。

Abstract: Promoting the green and low-carbon transformation of mariculture is of great value for achieving the carbon peak and carbon neutrality goals and advancing the sustainable development of fisheries. Taking Dalian’s mariculture industry as a case study, this paper employs literature analysis and case study methods. Based on a systematic review of research progress on carbon emissions and green transformation in mariculture at home and abroad, it thoroughly examines the practical dilemmas restricting Dalian’s mariculture green transformation and explores targeted promotion paths. The study reveals that major obstacles include extensive breeding modes coupled with inadequate carbon accounting, insufficient supply and promotion of low-carbon technologies, weak motivation among farming operators, and imperfect policy incentives and constraints. Introducing path dependence theory, the analysis indicates that self-reinforcing mechanisms exist among these dilemmas, forming a lock-in state that impedes transformation. Breaking through this predicament requires collaborative efforts from four dimensions: carbon sink fishery layout, technology promotion system, capacity building of farming entities, and policy and institutional improvement.
