本文分析了替代燃料汽车的潜在需求。我们考虑的替代燃料车辆除了双燃料车辆外，还有液化丙烷气体和电动车辆。这些数据是从一项陈述偏好调查中获得的，其中每个受访者，在一个随机选择的样本中，暴露于15个实验。在每个实验中，受访者被要求根据受访者的偏好对三种具有特定属性的假设车辆进行排名。几个版本的随机效用模型制定和估计。它们包括一个用于排序数据的模型，以及允许不同类型的实验偏好相关性的模型。除一种情况外，模型规格是根据首选数据估计的。最通用的模型可以很好地预测第二和第三选择的总和。该模型被应用于评估替代燃料汽车的支付意愿。
This paper analyzes the potential demand for alternative fuel vehicles. The alternative fuel vehicles we consider are liquid propane gas and electric powered vehicles in addition to dual-fuel vehicles. The data were obtained from a stated preference survey in which each respondent, in a randomly selected sample, was exposed to 15 experiments. In each experiment the respondents were asked to rank three hypothetical vehicles characterized by specific attributes, according to the respondents' preferences. Several versions of a random utility model are formulated and estimated. They include a model for rank ordered data, and models that allow for different types of correlation in preferences across experiments. Apart from one case the model specifications are estimated from the data on first choices. The most general model turns out to predict aggregate second and third choices rather well. The model is applied to assess the willingness to pay for alternative fuel vehicles.
