The study deals with German consumers' attitudes towards organic food and local food, their food purchase behaviour and their personal characteristics. The purpose is to investigate the differences in attitudes and willingness-to-pay values between consumers who consider the organic production of food (very) important and those who consider it less important. This study combines a consumer survey with an in-store, discrete choice experiment. In the analysis, findings from the consumer survey were related to the choices made by consumers in the experiment. Consumers' preferences and willingness-to-pay values were estimated through random parameter logit modelling. Organic-minded consumers (i.e. those who regarded organic food production as (very) important in the survey) have stronger preferences and estimated willingness-to-pay values for organic as well as local products. Locally produced food, as opposed to food from neighbouring countries or non-EU countries, is preferred over organically produced food by both consumer groups which demonstrates that organic-minded consumers do not only consider organic food production as important, but also value local food production in a purchase situation. Hence, it can be assumed that local food production complements organic food production for the group of organic-minded consumers. This contribution is the first study dealing with local and organic food purchase behaviour in Germany that examines four different products and is carried out in rural as well as urban locations in four different regions. Due to the application of a choice experiment including no-choice options and binding purchase decisions, the results are expected to be closer to real purchase situations than results of direct questioning and choice experiments in online applications.
该研究探讨了德国消费者对有机食品和本地食品的态度、他们的食品购买行为以及个人特征。目的是调查认为食品有机生产(非常)重要的消费者与认为其重要性较低的消费者在态度和支付意愿值方面的差异。本研究将消费者调查与店内离散选择实验相结合。在分析中,将消费者调查的结果与消费者在实验中做出的选择相关联。通过随机参数logit模型估计消费者的偏好和支付意愿值。有有机意识的消费者(即在调查中认为有机食品生产(非常)重要的消费者)对有机产品和本地产品有更强的偏好和估计支付意愿值。与来自邻国或非欧盟国家的食品相比,两个消费者群体都更青睐本地生产的食品,这表明有有机意识的消费者不仅认为有机食品生产很重要,而且在购买时也重视本地食品生产。因此,可以假设本地食品生产对有有机意识的消费者群体而言是有机食品生产的补充。本研究是德国第一项针对本地和有机食品购买行为的研究,考察了四种不同的产品,并在四个不同地区的农村和城市地区开展。由于应用了包含无选择选项和有约束力购买决策的选择实验,预计结果将比在线应用中的直接提问和选择实验结果更接近实际购买情况。
