政府干涉对大宗货物双渠道低碳运输供应链的协调研究

Coordination Research on the Double Channel of Low Carbon Transport with Government Interference

建立一个两级的北江大宗货物供应链系统(分销商同时拥有水路运输渠道和公路运输渠道且以统一的价格向市场销售产品),分别研究政府改善水路运输服务基础设施策略以及政府对水路进行价格补贴策略对大宗货物供应链的影响。结果表明:两种策略不仅平衡陆水运输量,还能增加供应链成员的利润。且改善基础设施后的运量转移效果比政府补贴的效果明显。从短期来看,政府要实施价格补贴策略会较易取得水路运输平衡的效果;从长远来看,政府要实施政府改善基础设施策略才能深度开发水路运输资源。如此交替实施激励措施,才能有效地实现北江大宗货物低碳绿色运输的目标,促进北江大宗货物供应链行业的发展。

Based on the bei-jiang fiver commodities supply chain as the research background, this paper sets up a manufac- turer and a distributor of two-stage supply chain system. Distributors have water transport channels and highway transporta- tion channels, in a unified price selling products to the market. Distributors of waterway transport channels for price subsi- dies, as well as the government for low carbon green cargo＇s point of view, the water transportation channels to purchase products of consumer subsidies is studied respectively, under two kinds of price subsidy policy impact on bulk cargo in the supply chain. By analyzing the game relationship between supply chain members and the government, it finds their respec- tive optimal decision. Result shows that the two kinds of price subsidy policy can increase the water transportation. In the long run, the government to the implementation of the discrete price subsidy policy, and the distributor price subsidy policy used interchangeably to effectively promote the realization of bei-jiang river commodities the goal of low carbon transport.
