Fresh product is characterized by strong timeliness,low residual value,and high uncertainty.In order to comprehensively understand the optimum decisions of fresh product enterprises and the contract coordination of the supply chain,this paper uses the literature induction method to summarize the perishability characterization methods of fresh products,the optimal decision model of fresh food enterprises,and the channel contract coordination mechanism,and analyzes the further research direction.Suggestions for expansion are as follows:one is to incorporate market or consumer factors into the deterioration rate function;the second is to find a balance point between the entire chain of fresh-keeping investment and terminal shelf services and cost-effectiveness;the third is to design a contract mechanism with both revenue sharing and cost sharing functions.
