Cities, 2026年05月, ［査読有り］ - The role of brand commitment and external information in urban consumers’ organic produce choices: Evidence from Japan and China
Runan Yang; Hironori Yagi; Katsuhito Fuyuki, 筆頭著者, Although organic agriculture brands are growing globally, urban consumer uptake in East Asia remains modest. We examine how brand commitment and external certification information shape willingness to pay (WTP) for organic vegetables based on multiple-store memory model. Online surveys of adult urban consumers in Japan (n = 412) and China (n = 422) are followed by a choice experiment in which respondents are randomly assigned to external certification information. Using latent profile analysis, we segment consumers’ brand commitment into five groups and estimate conditional logit models of choice and WTP. Results show that higher brand commitment and external certification information increase WTP for organic cabbage and tomatoes. Among Chinese consumers, information does not significantly affect WTP for carrots, indicating product-specific value perceptions. In Japan, information about semi-organic certification raises WTP for tomatoes, especially among high-brand commitment segments. The study contributes theoretically by linking brand commitment with information sensitivity to explain consumer heterogeneity, and by highlighting the importance of tailored marketing strategies. Our findings emphasize the need for targeted communication to enhance organic produce consumption in urban Asian markets., Public Library of Science (PLoS)

Cities, 2024年12月, ［査読有り］ - How Does Information Influence Consumers’ Purchase Decisions for Environmentally Friendly Farming Produce? Evidence from China and Japan Based on Choice Experiment
Runan Yang; Katsuhito Fuyuki; Keeni Minakshi, 筆頭著者, In this research, 600 Chinese and Japanese consumers were divided into four groups to analyze consumers’ marginal willingness to pay for environmentally friendly farming (EFF) produce. We found that Chinese consumers had high awareness of green foods, while Japanese consumers were more familiar with organic produce than specially cultivated produce, perhaps because the latter has not yet received uniform national certification in Japan. Choice experiments show that EFF produce prices and consumers’ income critically affect consumers’ decision to pay, especially in China. After each group read different formal definitions of EFF produce, Chinese consumers still preferred green food certification, whereas Japanese consumers chose specially cultivated carrots. Both displayed different ideological purchasing behaviors through added interaction terms with an increase in education. When no information was given, Japanese consumers’ purchasing decisions became more positive as their education levels rose. Possibly, highly educated Chinese consumers emphasize pragmatism, whereas Japanese consumers emphasize the connection between environmental protection and agriculture. Therefore, EFF messaging should be differentiated by region. For distributors committed to international trade in EFF products between developing and developed markets, we suggest lower costs, differentiated product messaging, and community initiatives events to enhance trade and marketing in both China and Japan., MDPI AG
Sustainability, 2022年08月02日, ［査読有り］ - Japanese Consumers’ Willingness to Pay for Environmentally Friendly Farming Produce Based on Consumer Trustfulness
Runan Yang; Nina Takashino; Katsuhito Fuyuki, 筆頭著者, Abstract
In the past decade, the market share of environmentally friendly farming (EFF) produce in Japan has witnessed relatively rapid growth. However, consumer awareness and purchasing experience of this agricultural produce are still lagging. To study how awareness of EFF produce influences consumer psychology and purchase decisions, we use ordered logistic regression and choice experiments to analyze 600 survey responses collected through online questionnaires. The results show that information from friends and family can have a positive influence on Japanese consumers’ trust in EFF produce. Consumers also show a significant preference for EFF produce in the short term after receiving information about it. By setting up a control group for comparison, we find that, in addition to information, consumer education and income also positively and significantly affect the decision to purchase EFF produce. This study presents a unique perspective between information and consumer decision-making and provides targeted solutions for the promotional and marketing strategy problems faced by EFF produce sellers in Japan. We argue that strengthening regional publicity methods such as community events can enhance EFF producers’ marketing strategies., Walter de Gruyter GmbH
