考虑碳排放的农产品多级冷链物流网络均衡模型研究

An Equilibrium Model of Multi-level Cold Chain Logistics Network of Agro Products with Consideration of Carbon Emissions

构建由农业合作社、批发商以及零售商构成的三级农产品冷链物流网络,分别研究不考虑碳排放、考虑碳排放两种情形下农产品物流网络系统的均衡问题。并在考虑碳排放的情形下,对零售商订货次数、碳排放成本进行参数分析。研究表明:考虑碳排放后,系统销售给外部需求市场的农产品数量上升,价格也上升,从而系统整体利润也明显增长;当零售商增加订货批次时,应该设法增加对外部需求市场产品交易量而非提高产品价格来维持系统整体利润,而若碳排放成本增加,则应该提高产品价格。

This study establishes a cold chain logistics network consisting of agricultural cooperatives, wholesalers and retailers, and analyzes respectively the equilibrium conditions of agro products logistics network both with and without the consideration of carbon emissions. It then makes a parametric analysis on the retailers number of orders and carbon emission costs. The results show two findings. First, when taking carbon emission into consideration, the agro products sales to external market by the whole system increases and the price also rises, which leads to a marked increase of profits of the whole system. Second, when retailers increase the number of orders, they should increase the transac- tion volume rather than the price; and if the cost of carbon emissions increases, the product price should increase.
