政府补贴下考虑企业环保努力的闭环供应链决策分析

Decision-Making Analysis of Closed-Loop Supply Chain Considering Environmental Protection Efforts of Enterprises under Government Subsidies

在消费者具有环保意识的背景下,分析有无政府补贴时制造商环保努力对各节点企业价格、需求、利润等决策的影响,并进一步探讨补贴在各类最优策略中的作用。研究表明:环保努力能提高两类产品销售价格、扩大新产品需求,但对再制造品需求无影响;存在最优环保努力水平,使无政府补贴下制造商及系统整体利润最大;一定范围内补贴能遏制环保努力导致的再制造品销售价格上升,但对新产品价格无影响,且对零售商来说高补贴未必能带来高收益;消费者环保意识和制造商环保努力可以通过政府补贴影响产品需求和企业收益。

Under the background of consumers'environmental awareness,in order to analyze the impact of manufacturer's environmental protection efforts on the price,demand,profit and other decisions of node enterprises with or without government subsidies,and further explore the role of subsidies in various optimal decisions.The results show that:environmental protection efforts can increase the sales price of new products and remanufactured products,expand the demand for new products,but have no impact on the demand for remanufactured products;there is an optimal level of environmental protection efforts to maximize the profits of manufacturers and systems without government subsidies;within a certain range,subsidies can curb the increase of sales price of remanufactured products caused by environmental protection efforts,but have no impact on the price of new products,and higher subsidies may not bring higher profits to retailers;consumers'environmental awareness and manufacturers'environmental protection efforts can affect the quantity of product demand and enterprise income through government subsidies.
