【摘要】：森林碳汇已成为缓解气候变化、减少碳排放的创新途径。南方集体林区林改后小规模农户将成为森林碳汇的主要供给主体。由于森林碳汇是生态补偿市场化的新形式,农户的社会风险偏好态度将影响其碳汇供给的意愿和决策。因此分析南方集体林区不同风险类型农户的碳汇供给意愿,对于今后在南方集体林区产权主体分散的情况下明确碳汇供给主体,提高激励碳汇经营主要供给群体政策的瞄准度具有重要现实意义。论文通过浙江省5个案例县(市)183户林农的调查和风险偏好实验,测度了农户风险偏好,共获得风险偏好、风险中性和风险厌恶的农户样本分别为72,33,78个,在对农户的碳汇供给意愿进行描述性统计基础上,运用二元Logit模型分析了影响农户碳汇供给意愿的影响因素,包括风险偏好、个体异质性、社会资本和组织制度。结果显示:风险厌恶型农户的碳汇供给意愿显著高于风险偏好类农户;林地资源规模对于碳汇供给意愿有积极作用;政府造林营林的补贴等外部政策制度变量也会显著激励家庭的碳汇供给意愿。为此国家需要努力引导成立碳汇交易中介,减少风险厌恶型农户进入碳汇市场的交易成本;鼓励通过林地流转等行为促使林地规模经营,引导具有一定经济实力的规模大户和社会资本率先开发碳汇交易项目;在南方集体林区重点加大对小规模林农的营造林补贴,提高林农碳汇经营的积极性。
[Abstract]:The forest carbon sink has become innovative ways to mitigate climate change, reduce carbon emissions. In southern collective forest areas in small scale farmers will be the main supply of the main forest carbon sink. Because forest carbon sequestration is a new form of ecological compensation market, social risk preferences of farmers will affect the carbon supply willingness and decision-making. Therefore, carbon sequestration the analysis of different types of farmers willingness to supply risk in southern collective forest area, for the scattered in southern collective forest property rights under the condition of clear body of carbon supply, improve the incentive aim carbon management policy of the main supply group has important practical significance. This paper through the Zhejiang Province 5 county (city) case investigation and risk preference experiment 183 farmers the measure of the farmers' risk preference, total risk preference, risk neutral and risk averse farmers samples were 72,33,78, the farmers of carbon Descriptive statistics based on exchange willingness to supply two yuan, the use of Logit model to analyze the influencing factors of farmers' willingness to supply carbon sequestration, including risk preference, individual heterogeneity, social capital and organizational system. The results showed that carbon sequestration supply will risk averse farmers' risk preference significantly higher than that of farmers; forest resource scale has a positive effect for carbon sequestration supply; government afforestation subsidies policy system will be significantly variable external incentive family. Therefore carbon supply will need to guide the establishment of national carbon trading intermediaries, reducing the transaction cost of risk averse farmers into the carbon market; encouraged by forest land circulation behavior to forest scale management, guide has a certain economic strength the large scale of social capital and pioneered the development of carbon trading projects; in the southern collective forest area and increase the focus on small scale forest The farmers' subsidies to build forests improve the enthusiasm of the forest farmers to manage carbon sequestration.
