摘　　要：在一个由生鲜农产品销售商、上游的供应商和3PL组成的供应链中,存在着销售商是否向供应链上游成员共享需求预测信息以及上游成员之间是否传递信息这一对矛盾的问题。本文考虑3PL保鲜努力对生鲜农产品新鲜度的影响,通过构建完全信息共享、部分成员信息共享以及无信息共享策略下生鲜农产品供应链多主体的博弈模型,分析了不同信息共享策略下的最优定价和保鲜努力决策,进而研究了销售商的信息共享策略。在此基础上,设计激励契约对信息共享策略进行改进,并探讨了激励契约对供应链均衡决策的影响。研究表明,销售商仅向3PL共享信息对自身最有利,但由于3PL和供应商之间存在信息传递,当新鲜度弹性较高时,信息共享均衡策略为完全信息共享;当新鲜度弹性较低时,信息共享均衡策略为无信息共享。而供应链整体绩效在销售商仅向3PL共享需求信息时达到最优。由此,销售商可以设计转移支付契约以规避上游成员之间的信息传递。契约实施后,在高市场需求信息下,生鲜农产品的品质得以提升,且对于新鲜度弹性较高的生鲜农产品,其销售价格还会降低。As the consumption level rises,the price of fresh produce is not the only concern of consumers,but the quality of fresh produce is gradually becoming a focus.In order to ensure the quality during the distribution process,fresh produce companies often choose third-party logistics(3PL)with cold chain resources to preserve freshness.3PL’s fresh-keeping effort affects the demand for fresh produce,and plays an important role in the profitability of fresh produce companies as well as the overall performance of the fresh produce supply chain.However,the market demand uncertainty makes operational decisions on fresh-keeping effort and pricing dif⁃ficult.It may result in too much or too little investment of fresh-keeping resources,leading to efficiency loss of the fresh produce supply chain.Compared with the supplier and 3PL,the retailer has an information advantage about demand forecast and may choose to share demand information to eliminate information asymmetry.Thus,there is a contradictory question of whether the retailer shares demand forecast information with the upstream members and whether upstream members transmit information to each other.To address this problem,the information sharing strategy in the fresh produce supply chain considering 3PL’s fresh-keeping effort is investigated.There are four parts as follows.First,considering the impact of the 3PL’s fresh-keeping effort on freshness,a multi-subject game model of the fresh produce supply chain is established under complete information sharing strategy,partial information sharing strategy and no information sharing strategy,and the optimal pricing and fresh-keeping effort decisions are analyzed.Second,information sharing preferences of sup ply chain members are analyzed and the retailer’s information sharing strategy is investigated.Third,based on the overall performance of the supply chain under different information sharing strategies,an incentive contract is designed to adjust the information sharing strategy.Finally,the impacts of the contract o
