This paper sets Stackelberg model of bilateral quality efforts decision dominated by supermarket in the agricultural products supply chain by considering fairness concern and altruistic reciprocity. We use backward induction method to compute and prove that A3P’ fairness concern can play the role of profit distribution mechanism in agricultural products supply chain, and has no effect on the bilateral quality efforts decision, total profit of supply chain and objective efficiency, but can improve both the subjective and objective fairness degree. Meanwhile, supermarket’s altruistic reciprocity can improve the total quality efforts and total profit of supply chain, optimize the objective efficiency and subjective fairness of supply chain.

Promoting waste sorting and recycling in colleges and universities is of great significance for building a green campus. Taking Tianjin Agricultural College as an example, this paper investigates the recent situation of waste classification in colleges and universities.
