绿色产品市场中政府最优补贴政策的确定

Determination of Optimal Government Subsidy Policy in Green Product Market

在绿色供应链管理中考虑消费者偏好、绿色度等因素,分别建立政府补贴绿色生产者、消费者两种补贴政策下的两阶段博弈模型,并通过数值仿真分析两种补贴政策下政府补贴效果的差异。研究表明:两种补贴政策均能促进绿色产品的发展,当补贴力度较小时,两种补贴政策的效果差异不大;但当补贴力度增强时,政府补贴消费者可以在更大程度上提高消费者对绿色产品的需求,为绿色生产者带来更大收益,同时也更能增进社会福利,进而能够更有效地促进绿色产品业的发展。

In order to explore the effect of different subsidy policies,this paper establishes a two- stage game model of government subsidizing green producers and consumers by taking into account factors such as consumer preference and green degree in the green supply chain management. Through using the method of numerical simulation, this paper analyses the difference between these two kinds of government subsidy policies. The results show that both two subsidy policies can promote the development of green products. When subsidy level is very low, the gap between two kinds of subsidy policy is not great. However, with subsidy level gradually being increased, the policy of government subsidizing consumers can increase consumer demand for green product to a greater extent, bring greater benefits for green producers, better promote social welfare, and furthermore, promote the development of green industry more effectively.
