针对农产品冷链企业分担全部社会责任动力不强的问题,提出分担有限社会责任的设想.在需求依赖于价格和保鲜水平的假设条件下,就供应商与第三方物流服务提供商(third-party logistics service provider,3PL)分担、供应商与零售商分担、零售商与3PL分担有限社会责任等三种模式,构建供应商、3PL和零售商的序贯博弈模型,求解最优批发价格、零售价格和保鲜水平.通过比较社会福利和利润,选择最优的有限社会责任分担模式,并设计促成帕累托效率改善的保鲜成本分担协调机制.结果显示:当供应商的分担比例满足阈值条件,供应商与3PL分担有限社会责任是最优的分担模式,能够实现保鲜水平最高和社会福利最大.尽管零售商不参与分担社会责任,但是分担3PL的保鲜成本能够促进三方利润增加,进而从供应商与3PL分担有限社会责任的行为中获益.
Selection of limited social responsibility sharing modes in agricultural product cold chain
Aiming at the problem that enterprises in the agricultural product cold chain doesn't have strong motivation to share all social responsibilities,the idea of sharing limited social responsibility is proposed.Under the assumption that demand depends on price and freshness-keeping level,in terms of three modes of sharing limited social responsibility between suppliers and third-party logistics service providers(3PLs),suppliers and retailers,and retailers and 3PLs,a sequential game model for suppliers,3PLs,and retailers is built.The optimal wholesale price,retail price,and freshness-keeping level are figured out.By comparing social welfare and profits,the optimal limited social responsibility sharing mode is selected and a coordination mechanism for freshness-keeping cost-sharing is designed to improve Pareto efficiency.The results shows that,when suppliers'sharing ratio meets the threshold condition,sharing limited social responsibility between suppliers and 3PLs is the optimal sharing mode,which can achieve the highest freshness-keeping level and the maximum social welfare.Although retailers do not participate in sharing social responsibility,sharing the freshness-keeping costs of 3PLs can increase profits of three parties,thereby benefiting from the limited social responsibility sharing behavior between suppliers and 3PLs.
