绿色供应链中消费者信用支付策略研究

Research on Consumer Credit Payment Strategy in Green Supply Chain

本文考虑了一个由单一供应商和单一电商平台组成的绿色供应链,分析了三种不同支付策略(立即支付策略、分期付款策略以及最低还款策略)对供应链成员最优决策和利润的影响。研究表明:(1)免息期敏感系数对绿色营销水平和供应链成员利润均有正向影响。(2)信用支付会使产品产生溢价现象。但在一定条件下,信用支付策略可同时提高供应链成员利润和绿色营销水平,实现经济绩效和环境绩效的双赢。(3)手续费率较高时,若信用期限系数较小,立即支付策略最优;若信用期限系数适中,分期付款策略最优;否则最低还款策略最优。手续费率较低且信用期较小时,最低还款策略最优,否则立即支付策略最优。在此基础上,针对两种信用支付模型设计了成本分担和收益共享的组合契约,实现了供应链协调。

This article considers a green supply chain composed of a single supplier and a single e-commerce platform and analyzes the impact of three different payment strategies(immediate payment strategy,installment strategy and minimum repayment strategy)on the optimal decisions and profits of supply chain members.The research shows that:(1)grace period sensitivity coefficient has positive effects on the green marketing level and the profits of supply chain members.(2)Credit payment will cause premium phenomenon for products,but under certain conditions,the credit payment strategy can improve the profits of supply chain members and the green marketing level at the same time,and induces a win-win situation in both economic and environmental performances.(3)When the processing fee rate is high,if the credit term coefficient is small,the immediate payment strategy will be the best.If the credit term coefficient is moderate,the installment strategy will be the best.Otherwise,the minimum repayment strategy will be the best.The minimum repayment strategy will be the best if the processing fee rate is low and the credit period is small,otherwise the immediate payment strategy will be the best.On this basis,a combination contract of cost sharing and revenue sharing is designed for two credit payment models to coordinate the supply chain.
