Coordination of Automobile Supply Chain Considering Relative Endurance Level under the Dual-Credit Policy

The implementation of the dual-credit policy has had a significant impact on the development of new energy vehicles. Considering the background of the dual-credit policy, this paper examines the concept that demand is influenced by price, consumer low-carbon preference, and concerns regarding endurance. First, we study the pricing decisions of a two-level automobile supply chain consisting of two manufacturers and one dealer and discuss the influence of the dual-credit policy on decision making. Two methods are then used to coordinate the supply chain, and the results are verified by numerical analysis. The results show that: (1) the stronger the concerns of consumers regarding a low-carbon preference and endurance, the better the development of new energy vehicles; (2) raising the integral calculation coefficient and the integral price can increase the demand for, and profits from, new energy vehicles, which can expand the market; and (3) the supply chain can be fully coordinated through Nash negotiations. This paper theoretically demonstrates the impact of factors such as car endurance on corporate decision making, guiding car companies to make pricing decisions based on market conditions.
