摘要 针对农户的选择偏好,引入基于Logit的离散计量分析模型,以研究秸秆收购价格、成本及政府补贴对农户生物质供应选择行为的影响。在此基础上,应用主从博弈模型对生物质供应链中加工厂、收集站和农户等不同利益主体之间的决策进行分析,确定了最优的生物质收购价格及收集站的服务半径。最后,通过算例分析验证了上述优化决策模型的有效性。研究表明,农户供应模式的选择与其对效用的敏感程度有关;政府实行补贴激励不仅能提高农户将秸秆直接送至加工厂的积极性,对加工厂和收集站的利益也有不同程度的提高。

英文摘要 Considering the choice preference of farmers, this paper introduced a Logit-based discrete econometric analysis model to study the influence of straw purchase price, cost and government subsidy on the biomass supply choice behavior of farmers. On this basis, this study applied the Stackelberg game model to analyze the decision-making among different stakeholders in the biomass supply chain, such as biorefinery, collection stations and farmers, and determined the optimal purchase price of biomass and the service radius of collection stations. Finally, it used a numerical example to verify the effectiveness of the optimal decision-making model. The research shows that the choice of farmer's supply mode is related to their sensitivity to utility; government subsidies can not only improve the enthusiasm of farmers to send straw directly to the biorefinery, but also improve the interests of the biorefinery and collection stations to different degrees.
