Abstract

Choosing an effective subsidy mode is crucial for promoting the healthy development of the biofuel ethanol industry. After considering the differences in the social welfare effects of different subsidy models, we construct a Stackelberg game model to examine the chain of the fuel ethanol industry consisting of a downstream channel intermediary as the leader and an upstream production enterprise as the follower. We then discuss how the R&D subsidy mode and production subsidy mode affect social welfare, and what kind of subsidy mode should be adopted under different conditions. The study found that different subsidy modes affect corporate profits and consumer surplus by affecting the price and demand of fuel ethanol, which in turn affect the level of social welfare. In addition, the study found that both R&D subsidy mode and production subsidy model are not always efficient. The optimal subsidy mode depends mainly on the R&D difficulty coefficient and the slope of the inverse demand function.
我国生物燃料乙醇补贴模式的分析与比较
选择有效的补贴模式是促进生物燃料乙醇产业健康发展的关键。在考虑不同补贴模式的社会福利效应差异的基础上,本文构建了一个Stackelberg博弈模型,对以下游渠道中介为龙头、上游生产企业为从者的燃料乙醇产业链条进行了研究。然后讨论了研发补贴模式和生产补贴模式对社会福利的影响,以及在不同条件下应采取何种补贴模式。研究发现,不同的补贴模式通过影响燃料乙醇的价格和需求来影响企业利润和消费者剩余,进而影响社会福利水平。此外,研究发现研发补贴模式和生产补贴模式并不总是有效的。最优补贴模式主要取决于研发难度系数和需求逆函数的斜率。
