Differential Game Analysis Of Green Supply Chain Considering Delay Effect And Member Behavior

With the enhancement of consumers’ awareness of environmental protection,the construction of green supply chain is becoming more and more important.This requires both technological development by manufacturers and advertising by retailers,but there exist delayed effect.Therefore,in this paper,the differential game model is used to describe the long-term dynamic game process between the manufacturer and the retailer,while the delay effect is included in the research scope to simulate the interval from investment to achievement,which is more in line with the actual situation.Along the supply chain,manufacturers,consumers and the government are identified as the three main research objects,and the effects of the manufacturer’s risk-averse behaviour,consumers’ regretful behaviour and different government subsidy policies on the supply chain strategy and performance are studied respectively.Finally,targeted cost sharing model is used to optimize the supply chain.Specific research contents are as follows:(1)The manufacturer’s risk-averse attitude is studied.The benchmark model,the riskaverse model and the retailer’s cost sharing model are constructed respectively.The results of manufacturer’s research effort level,retailer’s advertising effort level,product green level and enterprise goodwill under these three models are studied respectively,and the influence of risk aversion attitude on supply chain strategy and performance is compared and discussed.The threshold values of key parameters of the retailer’s cost-sharing strategy are discussed,and the conclusions are verified by numerical simulation and displayed visually.Finally,based on the analysis results,reasonable suggestions for enterprise management are put forward.(2)Research is conducted on consumer regret behaviour.The benchmark model,the regret model with consumer regret behaviour and the two-way cost-sharing model are constructed,and the results of the manufacturer’s technological research effort level,the retailer’s advertising effort level,the product green level and the firm’s goodwill are investigated under these three models respectively.The impact of consumer regret on supply chain strategies and performance is compared and discussed,and the key parameters of the two-way cost-sharing strategy to compensate for the impact are discussed.The thresholds of the parameters are discussed,and the findings are verified and visualized through numerical simulations,and finally,reasonable suggestions are made for business management based on the analysis results.(3)Research for government subsidy policies.The benchmark model,the research subsidy model,the manufacturer cost-sharing model,the volume subsidy model and the retailer cost-sharing model are constructed,and the results of the manufacturer’s technological research effort level,the retailer’s advertising and promotion effort level,the product green level and the firm’s goodwill were investigated under these five models respectively,and the impact of the research subsidy policy and the volume subsidy policy on supply chain strategies and performance were compared and discussed respectively.The thresholds of the key parameters for different sharing strategies to compensate for the impact are discussed,and the findings are verified and visualised through numerical simulations,and finally reasonable suggestions are made for firm management based on the analysis results.
