双渠道背景下低碳供应链决策及渠道合作策略

Low Carbon Supply Chain Decision-making and Channel Cooperation under Dual Channel Background

考虑消费者低碳偏好和渠道偏好属性,在制造商主导的两级供应链下,构建制造商未开通线上渠道、制造商开通线上渠道以及制造商开通线上渠道且共享收益这三种情景下的低碳供应链决策模型。研究发现,制造商开通线上直销渠道会带来碳排放水平的提高和制造商利润的增加,当偏好线上渠道的消费者比例达到一定水平,零售商的利润受损。当制造商开通线上直销渠道且共享收益给零售商时,存在一个收益共享比例区间,能够同时实现碳减排水平、制造商和零售商利润的Pareto改善。最后,通过数值算例分析了消费者低碳偏好系数、线上偏好比例以及交叉价格弹性等参数的敏感性,并验证了制造商共享收益的策略有效性。

Considering consumers’low-carbon preferences and channel preference attributes,this paper constructs a low carbon supply chain decision model with the manufacturer do not open online channels,the manufacturer open online channels,and the manufacture open online channels and revenue shared under the two-tier supply chain structure dominated by the manufacturer respectively.Result shows that the manufacturer opening online direct sales channels will bring about higher carbon emission levels and improve the manufacturer’s profit.When the proportion of consumers who prefer to online channels reaches a certain level,the retailer’s profit will be damaged.There is a profit-sharing ratio range,in which the carbon emission reduction level and the manufacturer’s profit as well as the retailer’s profit can achieve Pareto improvement simultaneously.Finally,the sensitivities of system parameters such as low-carbon preference coefficients,online preference ratios,and cross-price elasticity are analyzed by the numerical examples.The effectiveness of the strategy with the manufacturer sharing revenue is verified.
