A Conjoint/Logit Analysis of Consumers’ Responses to Genetically Modified Tofu in Taiwan
基于台湾消费者调查数据，用联合分析和Logit模型发现品牌最重要、价格次之、转基因含量影响最小，但存在三个细分市场，其中两个对转基因豆腐有偏好或反感，表明转基因标签对消费者有帮助。
Abstract We use data collected from a consumer survey of face‐to‐face interviews to determine consumer demand for genetically modified (GM) tofu attributes in Taiwan. Conjoint analysis using logit models reveals that, on average, brand is the most important attribute in terms of influence on consumers’ preferences, followed by price, with GM content having the least influence. However, the analysis also reveals three distinct market segments for tofu. Apart from the largest segment (which reflects the average lack of concern about GM food), the remaining two segments are split according to their preference or antipathy towards GM tofu. This result suggests that GM labelling is helpful to Taiwanese tofu consumers.
