Cooperation quality supervision and coordination in two-stage supply chain of agricultural product logistics service

Considering a two-stage supply chain structure including an agricultural product logistics service integrator and a vendor, a basic gaming model for quality coordination of cooperation in logistics service supply chain is established. Then the logistics service integrator can choose to make quality supervision or otherwise the supplier can accomplish the cooperation according to the quality contact or choose to cheat. So, this paper witnesses the result of the mixed strategy Nash equilibrium of the gaming model and discusses the influence on quality coordination resulted from the competition among the logistics suppliers. Hence the new Nash equilibrium is obtained.
