摘　　要：为了探究海水养殖业的碳汇机理,以贝、藻养殖碳汇为研究对象,运用4种效率分析模型对我国贝藻类养殖业的碳汇效率作出评价。结果表明:在沿海各地中,辽宁省贝藻类的养殖过程不仅注重实践生产中的效率值,也比其他地区更关注实际投入产出过程中的效果现实程度,能将可移出碳汇的“生态-经济-社会”综合效益最大化地实现,对于其他区域具有一定的示范作用;广西的劳动力投入规模和土地投入规模存在严重失衡,并且对应着“高效率低效果”的贝藻类养殖投入产出,其专业从业人员的管理方式存在低效性;海南省贝藻类碳汇量产出率十分有限,其碳汇效应对海南省经济、社会及生态系统的影响不显著。另外,基于投入产出规模的公共权重方法,提出我国贝藻类养殖业中二氧化碳的初始吸收额度的分配方案。本文的边际贡献在于:首次将绩效型综合效率模型应用到贝藻类养殖碳汇的测算,使碳汇值兼顾效率和效果;且以基于公共权重的投入产出规模角度提出贝藻类养殖碳汇的碳吸收配额;通过公共权重方式,将效率因素纳入碳吸收配额,用投入产出规模和效率相结合来分配碳吸收配额,补充了基于DEA的新的分配方法。对我国沿海地区渔业碳汇发展和碳交易市场机制的完善具有一定政策意义。In order to investigate the carbon sink mechanism of marine aquaculture,the carbon sink of shellfish and algae aquaculture was taken as the research object,and four efficiency analysis models were applied to evaluate the carbon sink efficiency of shellfish and algae aquaculture in the coastal areas of China.The results of the study show that among the coastal areas,the shellfish and algae farming process in Liaoning Province not only pays attention to the efficiency value of practical production,but also pays more attention to the realistic degree of the effect of the actual input and output process than other regions,which can bring the"ecological-economic-social"benefits of removable carbon sinks into full play,and has a certain demonstration effect for other regions;In Guangxi,there is a serious imbalance between the scale of labor input and the scale of land input,which corresponds to the input and output of shellfish aquaculture with"high efficiency and low effectiveness",and the management of its professional practitioners is inefficient;in Hainan Province,the output rate of shellfish carbon sinks is very limited,and the function of carbon sinks generated by shellfish aquaculture makes very little economic,social and ecological contribution to Hainan Province.The economic,social and ecological contribution of shellfish aquaculture to Hainan Province is negligible.In addition,based on the public weighting method of input-output scale,the allocation scheme of the initial CO_(2) absorption credit in shellfish aquaculture in China is proposed.The marginal contributions of this paper lie in the following.Firstly,applying the performance-based integrated efficiency model to the measurement of shellfish aquaculture carbon sinks for the first time makes the value of carbon sinks can take account into both efficiency and effectiveness.Secondly,it proposes the carbon absorption quota of shellfish aquaculture carbon sinks from the perspective of input-output scale based on the public weighting approach.Thirdly,it inco
