英文文献摘要：
The relationship between nutrition knowledge and consumers’ food behavior has been debated for years. This may be partially attributed to the difficulty introduce by endogeneity of nutrition knowledge in econometric modeling. Using grass-fed beef as a vehicle, this paper investigates the impacts of consumers’ nutrition knowledge on their willingness to pay by accommodating the endogeneity problem using instrumental variable approach. Our results suggest that consumers’ nutrition knowledge significantly influences their willingness to pay for grass-fed beef. Gender and education are influential factors of consumers’ nutrition knowledge level.
这可能部分归因于计量经济学建模中营养知识的内生性难以引入。摘要本文以草饲牛肉为研究对象，运用工具变量的方法，透过内生性问题，探讨消费者营养知识对其支付意愿的影响。结果显示，消费者的营养知识显著影响其购买草饲牛肉的意愿。性别和文化程度是影响消费者营养知识水平的因素。
