“…These make the close strategic cooperation and coordination between the upstream and downstream enterprises in the food supply chain extremely important. Traditionally, the cooperation mode between upstream and downstream enterprises in the food supply chain includes two ways: one is to invest in the other party and provide guarantee for the other party's income to encourage it to join the cooperation, such as short-term capital injection, joint venture, integrated operation and other single capital behaviors (Gui et al, 2018 ); the other is to complement resources and share risks through long-term contracts, strategic cooperation and other ways, such as through revenue benefit sharing contract, wholesale price premium contract, cost sharing contract, and other ways to achieve diversified cooperation (Ghosh and Shah, 2015 ; Mensah et al, 2019 ; Post et al, 2019 ). These collaborations are usually based on a clear understanding of demanding a stable market and knowing the cost-benefit status of each cooperation subject, with the goal of maximizing the current profit of the food supply chain as the decision-making goal, and focus on discussing what kind of contractual or non- contractual form will bring the best profit to all participants to reach an optimal decision.…”
