Research On Cooperative Decisions Of Low Carbon Supply Chain Considering Behavior Preference

With the aggravation of environmental deterioration and the increasing shortage of resources,controlling carbon emissions and promoting emission reduction practices have become an inevitable trend for sustainable economic development.In this context,enterprises often adopt production emission reduction and low-carbon promotion to respond to increasingly strict environmental requirements and growing market demand.However,due to the limited low-carbon input capacity of a single enterprise,how to carry out cooperative decision-making in operation management has become an important way to promote the development of low-carbon supply chain.At the same time,the gradual emergence of consumers’ low-carbon preference and supply chain members’ fairness preference have further aggravated the complexity of decision-making environment.It is of great significance to consider behavior preferences into decision-making and cooperation mechanism of low-carbon supply chain.This research studies the cooperative decision-making of low-carbon supply chain based on consumers’ preference.We compare the decision results of sales price,emission reduction level and low-carbon promotion level under the three modes,a decentralized decision-making without the retailer’s promotion,a decentralized decision-making with the retailer’s promotion and a centralized decision-making with the retailer’s promotion.An emission reduction cost sharing contract,a promotion cost sharing contract and an emission reduction-promotion cost sharing contract are designed to coordinate the supply chain.Then the influence of consumers’ preference and different cooperation mechanisms on optimal decision-making and optimal profits is explored.The results show that the low-carbon promotion investment is conducive to improving the emission reduction level and achieving win-win profits for both members.The emission reduction cost sharing contract,the promotion cost sharing contract and the emission reduction-promotion cost sharing contract can encourage the manufacturer to invest in emission reduction and push the retailer to invest in low-carbon promotion,and improve the profits of supply chain.In addition,consumers’ preference is not only conducive to the improvement of low-carbon decision-making level,but also helps to promote the implementation of low-carbon supply chain cooperation mechanisms.Secondly,this research investigates the cooperative decision-making of low-carbon supply chain when the manufacturer has fairness preference.We compare the decision results of emission reduction level,low-carbon promotion level and promotion cost sharing ratio under three modes,a centralized decision-making,a decentralized decision-making with the manufacturer’s fairness neutrality and a decentralized decision-making with the manufacturer’s fairness preference.An incremental profit sharing contract based on promotion cost apportionment and an emission reduction-promotion cost sharing contract are designed to coordinate the supply chain.Then the influence of manufacturer’s fairness preference and different cooperation mechanisms on optimal decision-making and optimal profits is explored.It is found that the manufacturer’s fairness preference will not only reduce the emission reduction level and low-carbon promotion level,but also raises the boundary conditions for the sharing of promotion costs.The incremental profit sharing contract based on promotion cost apportionment and the emission reduction-promotion cost sharing contract can reduce the negative impact of the manufacturer’s fairness preference and encourage the manufacturer and retailer to invest in cooperation,thereby improving the performance of supply chain.
