考虑制造商竞争的绿色供应链政府补贴策略研究

Research on the Government Subsidy Strategy in Green Supply Chain with a Consideration of the Competition of the Manufacturers

为研究不同政府补贴策略对存在消费者绿色偏好以及两制造商横向竞争的绿色供应链的影响,分别建立和求解了三种补贴策略:无补贴策略、高成本制造商补贴策略、低成本制造商补贴策略。比较研究及数值仿真表明:政府补贴会提高直接受补贴产品的绿色度和需求量,但会降低无补贴产品的绿色度和市场需求量;制造商利润在直接受补贴下最高,补贴竞争者时最低;零售商和供应链总利润均在低成本制造商补贴策略下达到最高,其次是高成本制造商补贴策略;政府补贴只有在补贴力度适当时才能对供应链自身渠道利润产生正向作用。

In order to study the effects of government subsidy on the supply chain with consumers'green preference and the manufacturers'horizontal competition,three subsidy modes:no subsidy(NJC),subsidy to the high-cost manufacturer(JCX)and subsidy to the low-cost manufacturer(JCY)are established and solved.Comparative studies and numerical simulation show that government subsidy can increase the green degree and demand of the product affected by the subsidy directly while it can be counterproductive to another product.The manufacturer's profit achieves highest in the direct subsidy mode and lowest when the government's subsidy to the competitor.As far as retailer and the whole supply chain are concerned,their profits are highest in the mode JCY,followed by mode JCX,and government's subsidy have a positive effects to channel profits of supply chain only when the intensity of subsidy is suitable.
