Factors and evaluation models for the development of new energy electric vehicles in China

Abstract

The development of new energy electric vehicles in China is of great significance in addressing climate change, reducing dependence on fossil fuels, and promoting the growth of the clean energy industry. In this study, we establish a new energy electric vehicle development index model based on game theory portfolio empowerment. Firstly, 15 indexes related to the development of new energy electric vehicles were selected, and the optimal weights of the indexes were obtained by integrating AHP and EWM using game theory combination empowerment method, and the most important influencing factors were obtained. Then, 3 models, namely, TOPSIS, grey correlation analysis and principal component analysis, were used to evaluate the development index of new energy electric vehicles, and the results showed that the development level of China’s new energy electric vehicles from 2010-2021 shows a trend of yearly improvement, with the rate of improvement shifting from a slow increase to a rapid one.
