森林碳汇是减缓全球气候变暖的有效途径之一,林农参与碳汇经营已成为学界关注的焦点。新一轮林改后小规模林农成为森林碳汇的主要供给主体,探讨农户碳汇经营意愿对于激励碳汇经营主体政策瞄准度具有重要的现实意义。本文基于Putnam的社会资本理论,利用福建省欠发达山区344户林农的微观数据,运用Logistic模型实证分析了社会资本对林农参与碳汇经营意愿的影响。研究表明：（1）林农参与碳汇经营意愿不高,仅36.63%的受访农户表示愿意参与;（2）社会资本对林农参与碳汇经营意愿具有显著的促进作用,其核心变量对碳汇经营意愿的贡献大小排序依次是关系网络〉人际信任〉制度信任〉社会规范;（3）人力资本中受教育程度、物力资本中家庭纯收入、林地总面积、林地地块数也在不同程度上影响家庭林业碳汇经营意愿。社会资本被称为“穷人的资本”,尤其在欠发达山区,政府可结合林区乡土情景从其核心维度采取措施,调动林农参与碳汇经营意愿,同时考虑碳汇补偿制度中林农利益需求等。

英文摘要：

Forest carbon sequestration （FCS）is an effective way to reduce climate change. Rural household participation in FCS is a focus in China. After southern collective forest tenure reform, small-scale rural households are the main subjects for FCS supply, so discussing their willingness to participate in FCS has great practical significance for policy for carbon forest management. This paper is based on Putnam＇s theory of social capital and used survey data of underdeveloped areas in Fujian to analyze how social capital influenced rural household willingness for FCS according to logistic modeling. We found that the level of household willingness for carbon forest management was low at 36.63%. Social capital can significantly promote willingness for carbon forest manage- ment, and various dimensions of social capital contributed to driving household willingness to participate in carbon forest management at different levels： social network〉 interpersonal trust〉 institutional trust〉 social regulation. Human capital and physical capital variables also influenced rural household willingness for carbon forest management. Social capital is called ＇the capital of the poor＇, especially in undeveloped areas. The government should combine institutional arrangements with the practical situation in underdeveloped areas to raise the level of social capital and stimulate forest carbon sequestration management participation. At the same time, the government should consider the interests of households in forest carbon sink compensation systems.
