Decision-making on Technological Innovation and Cooperative Emission Reduction in Supply Chain of New Energy Vehicles in Low-carbon Environment
Under the goal of carbon peaking and carbon neutrality,low-carbon economy has become an important trend of industrial development in China.As one of the pillar industries of Chinese economy,the automobile industry is of great significance for promoting industrial transformation and upgrading and realiz-ing the goal of carbon peaking and carbon neutrality.New energy vehicles have many advantages such as en-ergy conservative,emission economical and environmental friendly,which is conducive to increasing finan-cial returns and ecological benefits,and is an important way to achieve low-carbon transformation of the au-tomobile industry.In the context of low-carbon development,taking the three-level new energy vehicle supply chain com-posed of a raw material supplier,vehicle manufacturer and dealer as the research object,we discussed the is-sue of technological innovation and cooperative emission reduction in the supply chain.Next,we intro-duced the price plus method to describe the price relationship among the three parties,took low carbon level and product reputation as state variables,and according to the technological innovation cooperation of enter-prises in the supply chain,built a differential game model under three situations of centralized decision-mak-ing,decentralized decision-making and benefit-sharing and cost-sharing contract cooperation.Then,using the optimal control theory,we obtained the optimal trajectories and profit of technological innovation deci-sion,low-carbon level and product reputation under the three situations.Through a numerical analysis,we discussed the coordination effect of contract on the supply chain,so as to provide a theoretical basis for stuy-ing the dynamic coordination of technological innovation and cooperation emission reduction in the supply chain of new energy vehicles.The research result shows that from the perspective of supply chain technology innovation,centralized de-cision-making is the best choice,but it is difficult to achieve in reality.Instead,the benefit-sharing and cost-sharing contract can promote the Pareto improvement of technological innovation input of each member of the supply chain so as to effectively coordinate the supply chain.In this paper we mainly analyzed the issue of emission reduction of a new energy vehicle supply chain through low-carbon technology innovation cooperation under decentralized decision-making,centralized decision-making and contract coordination respectively.Future research can consider the decision-making situation where the supplier,manufacturer or distributor cooperates with one party while compete for profit with another party,or extend the research scope to cover multiple manufacturers to provide a horizontal an-gel on the joint efforts of supply chain enterprises in emission reduction through technological innovation.
