英文文献摘要：
This work offers a new approach to the adoption of GM crop varieties by adopting the econometric methodology of the characteristics-based demand literature. A random utility framework was implemented through different specifications of a conditional (CL) and a mixed multinomial logit (MMNL) model of crop-variety choice. Willingness-to-pay and price elasticity estimates for traits were calculated. The MMNL approach demonstrates that individuals' tastes for some traits significantly vary across the population. Results further suggest that labor saving technologies have a much wider potential to be adopted. Overall, the use of a trait-based model to examine the adoption patterns of GM crop varieties among corn farmers in Minnesota and Wisconsin reveals a new set of results and lessons that classic adoption models cannot provide.
这项工作通过采用基于特征的需求文献的计量经济学方法提供了一种采用转基因作物品种的新方法。通过对作物品种选择的条件(CL)和混合多项式logit (MMNL)模型的不同规范，实现了随机效用框架。计算了特征的意愿支付和价格弹性估计值。MMNL方法表明，个体对某些特征的喜好在整个群体中显著不同。结果进一步表明，省力技术有更广泛的潜力被采用。总的来说，使用基于特征的模型来检查明尼苏达州和威斯康辛州玉米农民对转基因作物品种的采用模式，揭示了一套经典采用模型无法提供的新结果和教训。
