Blockchain=better food? The adoption of blockchain technology in food supply chain
通过服务设计工作坊和实验，研究了餐饮业采用区块链技术提升食品溯源和信任，进而提高客户满意度，并发现效果因餐厅类型和位置而异。
Purpose This study aims to investigate the integration of blockchain technology into the food supply chain within the restaurant industry. It focuses on how blockchain can be applied to enhance transparency and trust in tracking food sources, ultimately impacting customer satisfaction. Design/methodology/approach A service design workshop (Study 1) and three between-subjects experiments (Studies 2–4) were conducted. Findings Results indicate that blockchain adoption significantly improves traceability and trust in the food supply chain. This improvement in turn enhances customer satisfaction through perceived improvements in food safety, quality and naturalness. This study also notes that the effects of blockchain technology vary depending on the type of restaurant (casual or fine dining) and its location (tourist destinations or residential areas). Practical implications The findings offer practical insights for restaurant owners, technology developers and policymakers. Emphasizing the benefits of blockchain adoption, this study guides decision-making regarding technology investments for enhancing customer service and satisfaction in the hospitality sector. Originality/value This research contributes novel insights to the field of technology innovation in the hospitality industry. It extends the understanding of signaling theory by exploring how blockchain technology can serve as a tool for signal transmission in restaurant food supply chains.
