本研究使用 Probit 模型分析消費者對基因改造產品的接受度，探討態度、知識、信任、知覺利益與知覺風險對基因改造產品接受度的影響，並比較男性與女性消費者對基因改造產品的接受度差異，最後說明不同基因改造科技產品間消費者偏好的相關性。
　　全體消費者分析的結果中，態度、知識以及信任方面的因素分別會對部分基因改造產品的接受度有顯著的影響；知覺利益對每種基因改造產品的接受度都有顯著正向的影響，而知覺風險對每種基因改造產品的接受度都有顯著負向的影響；同時發現態度和信任方面的因素會透過知覺利益與知覺風險，再對基因改造產品的接受度產生影響。男性與女性對基因改造產品之接受度在統計上顯示有所差異，且男性較女性能夠接受基因改造產品。
　　同屬於非食用性的基因改造花卉與基因改造寵物之間顯示有正向且高度的相關，同屬於食用性的基因改造植物食品與基因改造動物食品之間亦有相同的相關性；而消費者對同屬於植物類的基因改造花卉與基因改造植物食品，或是同屬於動物類的基因改造寵物與基因改造動物食品，其偏好之相關性皆相對較低。如此可發現消費者對於基因改造產品的選擇偏向食用或非食用這樣功能性的考量。

　　This study analyzes consumer acceptance toward genetically modified (GM) products by using Probit model. We investigate the influences of attitude, knowledge, trust, perceived benefit and perceived risk on the acceptance of GM products. We also compare the differences of the acceptance toward GM products between male and female consumers. The correlations among respondents’ preference toward different GM products are also examined.
　　The results show that attitude, knowledge and trust have significant influences on the acceptance of selected GM products. Perceived benefit has a significant positive influence on the acceptance of all kinds of GM products, and perceived risk has a significant negative influence on them. We also find that attitude and trust have affected the acceptance toward GM products through perceived benefit and perceived risk. The acceptance levels toward GM products by males and females are different statistically. Males are more likely to accept GM products than females.
　　Consumer preferences toward GM flowers and GM pets have a significant positive and high correlation, so does the relationship between their preference toward GM plant food and GM animal food. The correlations between consumer preferences toward GM flowers and plant food as well as between GM pets and GM animal food are however shown to be relatively low.
