Study On Decisions Of Closed-Loop Supply Chain Under Government Guidance And Investment Sharing

In the full implementation of the 18 th and 18 th Plenary Session of the spirit of the five,in accordance with the promotion of ecological civilization and green development decision-making arrangements,adhere to the five major development concepts to accelerate the transformation of development,promoting industry transformation and upgrading of the main line of the environment,Requiring manufacturers to be fully responsible for the product life cycle,especially putting emphasis on the recycling of waste electronic products.Closed-loop supply chain has become an important way to standardize the recycling of waste electronic and electrical equipment.This article uses game theory,optimization,comparative induction and other methods to study the pricing decisions of closed-loop supply chain under government reward-penalty mechanism and manufacturer sharing fixed recovery investment.First of all,this paper sets up a closed-loop supply chain centralized situation,decentralized case without sharing fixed recycling investment situation,manufacturer sharing the fixed recycling investment and manufacturer sharing the variable recycling investment.We find,manufacturer sharing fixed investment can reduce the wholesale price,the retail price,the buyback price,improve the recovery rate,increase the profit of the manufacturer and the retailer,and the profit of the collector will increase with little sharing proportion.But the above decision solutions are still less than the centralized situation.Manufacturer sharing the variable recovery investment mechanism only plays a role in buyback price,while has no effect on other decision variables.Secondly,in order to eliminate the double marginal effect,this paper also considers the government incentive mechanism.We establish the model of reward and penalty mechanism,and the manufacturer sharing the fixed recovery investment model under the reward and penalty mechanism.Through the comparative analysis,the reward and punishment mechanism can improve the buyback price,reduce the wholesale price and retail price,improve the recovery rate,and when the reward and penalty strength meets certain condition,the recovery rate is higher than the centralized situation.After the combination of reward and punishment mechanism and the manufacturer sharing the fixed recovery investment,the effect of the mechanism is better than that of only considering the reward and penalty mechanism or only considering the manufacturer sharing the fixed recovery investment under theappropriate reward and penalty strength and the sharing proportion.Finally,based on the above model,we consider corporate social responsibility,we find: after considering corporate social responsibility,it is conducive to improving the consumer's products and business recognition,increasing market demand and the waste products Recovery,and the profitability of the members of the closed-loop supply chain also increase.
