This cross-country study investigates the relative role of organic labelling in consumers' purchase decisions for apples and the extent to which behavioral constructs, derived from an extension of the Theory of Planned Behavior, influence consumers' choices. We apply an Integrated Choice and Latent Variable Model, combining a discrete choice experiment with structural equation modelling. Empirical validation draws on data from an online survey conducted in three European countries (N=404; N=407; N=401). In all countries, price is by far the most important attribute in consumers' purchase decision of apples, followed by country-of-origin and production method. The results show considerable consistency across the investigated countries regarding the importance of behavioral constructs - attitudes, subjective norms, perceived behavioral control, trust, and personal moral norms - in explaining consumers' intentions to buy, and purchase choices for, organic apples, confirming the derived theoretical framework.
本跨国研究调查了有机标签在消费者购买苹果时的相对作用,以及源自计划行为理论延伸的行为结构在多大程度上影响消费者的选择。我们应用综合选择和潜在变量模型,将离散选择实验与结构方程建模相结合。实证验证基于在三个欧洲国家(N=404;N=407;N=401)进行的在线调查数据。在所有国家,价格都是消费者购买苹果时最重要的属性,其次是原产国和生产方法。结果表明,在所调查的国家中,关于行为结构(态度、主观规范、感知行为控制、信任和个人道德规范)在解释消费者购买有机苹果的意愿和购买选择方面的重要性,存在相当大的一致性,证实了推导的理论框架。
