There is a large literature about consumer acceptance of GM foods dating back almost three decades, but there are fewer studies that investigate how support for specific GM attributes contribute to general support for novel plant technologies. In addition, there is little information on how support has changed over time. Using survey data from 2018 to 2023 in a U.S. State (Vermont) ( = 3101), we analyze changes in support for a variety of GM attributes over time. There are three major findings. First, there is movement toward neutrality in support for various GM attributes, but opposition continues. Second, there is variability in support for different GM attributes. People are most supportive (least opposed) to GM attributes that improve flora (plant health or drought tolerance), and most opposed (least supportive) of attributes that impact fauna (specifically fish). Third, multivariate regression reveals that assessments of individual GM attributes contribute to levels of overall support of the use of GM technologies in agricultural production.
关于消费者对转基因食品的接受程度，已有近三十年的大量文献记载，但很少有研究调查对特定转基因属性的支持如何有助于对新型植物技术的普遍支持。此外，关于支持随时间变化的信息也很少。本文利用 2018 年至 2023 年美国一个州（佛蒙特州）（ = 3101）的调查数据，分析了一段时间内对各种转基因属性的支持的变化。有三个主要发现。首先，对各种转基因属性的支持有向中立转变的趋势，但反对仍然存在。其次，对不同转基因属性的支持存在差异。人们最支持（最不反对）改善植物群（植物健康或耐旱性）的转基因属性，而最反对（最不支持）影响动物群（特别是鱼类）的属性。第三，多元回归显示，对个别转基因属性的评估有助于对农业生产中使用转基因技术的总体支持水平。
