基于不同政府补贴方式的绿色产品闭环供应链决策研究

以制造商和零售商组成的绿色产品闭环供应链构建了政府对绿色产品仅生产补贴、仅回收补贴以及生产和回收同时补贴的3类绿色供应链模型.运用博弈论方法进行求解，研究发现：3类绿色供应链模型中的产品绿色度、市场需求量、制造商利润、零售商利润均与绿色度敏感系数成正相关关系.仅生产补贴和仅回收补贴两类绿色供应链模型中绿色度敏感系数满足一定条件时产品零售价与之成负相关关系.政府对绿色产品仅生产补贴时的市场需求量、绿色度、制造商利润、零售商利润均优于仅回收补贴和生产和回收同时补贴情形.政府对绿色产品生产和回收同时补贴时企业利润反而并不是最大的.因此，政府应加大对绿色产品的生产补贴力度，获得补贴的制造商应加大绿色产品研发力度.这样产品的绿色度得以进一步提升，环境得以进一步改善.

Research on Decision-Making of Closed-Loop Supply Chain of Green Products Based on Different Government Subsidies

In the context of a closed-loop supply chain of green products composed of manufacturers and retailers, this paper establishes three green supply chain models: government subsidies for producing green products, government subsidies for recycling green products, government subsidies for producing and recycling green products. Using game theory method to solve this problem, the study finds that the product greenness, market demand, manufacturer''s profit, and retailer''s profit in the three green supply chain models are positively related to the greenness sensitivity coefficient. In the green supply chain models of government subsidies for producing green products and government subsidies for recycling green products, the retail price is negatively related to greenness sensitivity coefficient when greenness sensitivity coefficient meets certain conditions. The market demand, product green degree, manufacturer''s profit and retailer''s profit in the scenario of government subsidies for producing green products are better than those in the scenario of government subsidies for producing and recycling green products. Corporate profits in the scenario of government subsidies for producing and recycling green products are not the largest. Therefore, the government should increase subsidies for the production of green products, and manufacturers subsidized should increase research and development of green products. In this way, the product greenness can be further improved, and the environment can be further improved.
