外包制造下政府补贴对低碳供应链影响分析

为分析外包制造下,政府补贴对低碳供应链竞争的影响,基于低碳产品外包制造,构建一个制造商、一个外包制造商和一个销售商组成的博弈模型。基于此模型,对比分析政府三种补贴策略对两种产品市场竞争机理的影响。研究得到:政府补贴给制造商或销售商时,单位委托制造价格要高于补贴给外包制造商时,也即,当政府采取补贴策略且不补贴给外包制造商时,外包制造商会通过增加单位委托制造价格转移政府补贴;政府补贴策略对单位普通产品批发价格和零售价格无影响,但政府补贴策略会减少普通产品销售量,增加低碳产品销售量;政府补贴虽然减少普通产品收益,但政府补贴增加低碳产品收益,且低碳产品增加收益大于普通产品减少收益,也即政府补贴增加制造商和销售商的利润;政府补贴策略减少两种产品对环境造成的影响,增加消费者剩余和社会剩余。

Analyzing the Effect of Government Subsidy on the Low-carbon Supply Chain Based on Outsourcing Manufacturing

In order to analyze the influence of government subsidy strategy on the low-carbon supply chain competition, the game model is established among a manufacturer, outsourcing manufacture and a retailer based on outsourcing manufacturing of low-carbon product. Based on this model, the effects of three different government subsidy policies between the two products is contrastively analyzed. The results are as follows through the studying: the unit outsourcing manufacturing price is more than the unit outsourcing manufacturing price, when government subsidizes low-carbon product through the vendor or the common product manufacturer; when government subsidizes the low carbon product manufacturer, i.e., the low carbon product manufacturer could transfer the government subsidies through increasing the unit outsourcing manufacturing price; when government does not subsidize the low carbon product manufacturer, government subsidy strategy has no effect on the unit wholesale price and the unit retail price of ordinary products, but it will reduce the sales volume of ordinary products and increase the sales volume of low-carbon products. Although government subsidies reduce the profit of ordinary products, they increase the profit of low-carbon greater than the reduced profit of ordinary products, i.e., government subsidies could increase the profits of two product manufacturer and sellers; The government subsidy strategy reduces the environmental impact on the two sides, increasing both the consumer and social surplus.
