基于林业碳汇基金减排购买协议模式的碳汇林经营策略研究
Strategies of carbon sink forest based on emission reduction purchase agreement model of forestry carbon fund
【目的】基于减排购买协议模式,考虑资金约束下林农借助林业碳汇基金进行融资问题,分析林农与林业碳汇基金运作主体的最优决策与利润情况,旨在为林农减排行为激励、碳汇市场机制完善及林业碳汇基金政策设计提供重要参考。【方法】以林业碳汇基金减排购买协议模式下的林农为研究对象,运用均值方差模型和Stackelberg博弈模型,研究林农的碳汇林经营规模及质量优化策略。【结果】林农风险规避性和碳汇产出随机性的提高均会降低碳汇林规模和总产量,但会促使林农更加注重碳汇林质量,而林农和基金运作主体期望利润水平将随之下降;碳汇市场价格提高会扩大碳汇林规模和总产量,但可能会导致林农忽视碳汇林质量,此时林业碳汇基金运作主体将提高碳汇收购价格,双方期望利润均将随碳汇价格提高而增加;提高政府补贴标准可以促进林农扩大碳汇林规模与总产量,但可能会导致碳汇林质量下降,基于此,林业碳汇基金运作主体将降低碳汇收购价格,双方期望利润均随补贴标准提高而增加。【结论】林业碳汇基金减排购买协议模式能够在一定程度上缓解林农资金约束,并在一定条件下赋能碳汇林扩绿、提质、增汇与增收。
【Objective】This study considers the financing of forestry farmers under financial constraints through forestry carbon sink funds, we examine the optimal decisions and profit outcomes of forestry farmers and the forestry carbon sink fund operators under the emission reduction purchase agreement model. The study aims to provide important an reference for incentivizing emission reduction behaviors of forestry farmers, improving the carbon market mechanism, and designing policies for forestry carbon funds.【Method】This study focuses on the forest farmers under the forestry carbon sink fund emission reduction purchase agreement model. By employing the mean-variance model and the Stackelberg game model, it investigates forest farmers’ strategies regarding the scale and quality of carbon sink forest management.【Result】Increased risk aversion of forestry farmers and greater randomness in carbon sink output reduce the scale and total output of carbon forests but lead to greater attention to carbon forest quality. However, the expected profits of both forestry farmers and fund operators decrease as a result. Higher carbon market prices expand the scale and total output of sink forests but cause forestry farmers to neglect carbon forest quality. In this case, the forestry carbon sink fund operators increase the carbon purchase price, and the expected profits of both parties rise with the increase in carbon market prices. Higher government subsidies encourage forestry farmers to expand the scale and total output of carbon sink forests but result in a decline in carbon forest quality. Consequently, fund operators lower the carbon purchase price, while the expected profits of both parties increase with higher subsidy standards.【Conclusion】The forestry carbon sink fund emission reduction purchase agreement model can, to a certain extent, alleviate the financial constraints of forest farmers and, under certain conditions, empower the expansion, quality improvement, carbon sequestration enhancement, and income increase of carbon sink forests.
