China’s vegetable supply chain faces challenges, such as the shortage of technologies for vegetable production, storage and preservation, imperfect rural finance services, and uncertainty in terms of vegetable production and sales. Companies and the Chinese government focus on food safety and security, as well as supply stability. The Meiyu Cooperative is a National Top 100 farmers’ cooperative in China that addresses these concerns successfully. It has established ‘a trinity cooperation mechanism’ to coordinate and integrate vegetable production, supply and sale, and financial credit. The cooperative has successfully built close relationships with farmers and companies, thus achieving financial, social, and environment benefits. This cooperation mechanism represents an innovative model for integrating the vegetable supply chain and providing necessary services based on farmers’ demands. This case study is addressed to senior undergraduate students and postgraduate students specialising in agricultural economics and can also be used for training administrators in food companies.
