A coupling coordination development model of new energy electric vehicles and ecological environment

Abstract

Analysing the degree of coupling and coordination between new energy electric vehicles and ecological environment in China is of great significance to optimize and enhance the development of new energy vehicles in China. This paper constructs the evaluation index system of China’s new energy development and ecological environment level respectively, and analyses the coupling and coordination level of the two based on the game theory combination empowerment method, the simulated annealing optimization projection tracing evaluation model and the coupling coordination degree model. The results show that the coupling degree of coordination gradually increases from 0.292 in 2010 to 0.828 in 2021, and the impact of the development of new energy electric vehicles on the ecological environment in China presents a positive and positive development year by year.
