Importance of the Federal Tax Credit: Clean Vehicle Rebate Project Data Used in 2020–21 Analyses

These data are from a survey of participants in the California's Clean Vehicle Rebate Project, a statewide consumer cash rebate for the purchase or lease of a qualifying clean vehicle. The survey data were used in analyses of the importance of the federal tax credit in making it possible to acquire an EV. In the analyses, characteristics associated with a participant in the Clean Vehicle Rebate Project finding the tax credit extremely important in making it possible to acquire an EV were examined using descriptive statistics and binary logistic regression. Dominance analysis was performed with parsimonious versions of logistic regression models to rank-order importance of significant factors.

本数据集源自针对加州清洁汽车退税项目（California's Clean Vehicle Rebate Project）参与者的调研。该项目为面向合格清洁汽车购买或租赁的全州性消费者现金退税计划。本次调研数据被用于分析联邦税收抵免在助力消费者购置电动汽车（Electric Vehicle, EV）方面的重要性。分析过程中，研究人员通过描述性统计与二元逻辑回归分析，对该项目参与者中认为该税收抵免对购置电动汽车至关重要的人群的相关特征展开了考察。此外，研究还采用基于简约版逻辑回归模型的优势分析方法，对各显著影响因素的重要性进行了排序。
