Decision Analysis of Dynamic Emission Reduction in Supply Chain under Equity Cooperation Mode
By introducing equity cooperation to form a community of interests,the impact of"hitchhik-ing"behavior can be reduced.Considering that the product emission reduction was constantly chan-ging,the time factor was introduced into the game model to achieve emission reduction,and the dif-ferential game model under three situations:non-equity cooperation,decentralized decision-making based on equity cooperation and centralized decision-making was constructed.The results show that compared with the situation without equity cooperation,the level of manufacturer's water reduction and drainage and retailer's promotion efforts have been improved under equity cooperation.However,under centralized decision-making,manufacturers have the highest level of emission reduction and pro-motion efforts,and equity cooperation is an important way to improve the enthusiasm of emission re-duction and promotion.The shareholding ratio needs to be within a certain range to promote manufac-turers'emission reduction and retailers'promotion.Manufacturers and retailers should comprehen-sively analyze and determine a reasonable shareholding ratio,so as to improve the manufacturer's wa-ter reduction and drainage level and the retailer's promotion efforts.Meanwhile,the change of share-holding ratio will also bring profit fluctuations to manufacturers and retailers.
