Abstract: Under the background of the national "double carbon" policy, how to realize energy conservation and emission reduction has become a top priority for economic development. The supply side and the demand side of the heavy truck industry are also looking for a way to balance emission reduction and profit, and the power change mode of the heavy truck is a good choice. The operation mode of "vehicle-electric separation" has overcome the pain points of low operating efficiency and high initial investment of battery electric heavy trucks. It can effectively meet the requirements of heavy truck high frequency operation vehicles, improve vehicle operation efficiency, return rate and traffic convenience, and have higher economic and environmental benefits. This paper analyzes the policy orientation, the environmental economic mechanism of the industrial chain and the market competition pattern of the heavy truck, which has reference significance for realizing the commercial promotion requirements of the heavy truck.
