Promoting the development of the new energy automobile industry in China: Technology selection and evaluation perspective

With the rapid development of new energy vehicles, China, as the largest producer, has achieved great success. However, weaknesses in the key technologies (KTs) have been exposed. Therefore, to aid China's new energy automobile market to further expand and to better understand the strengths and weaknesses of the current KTs, this paper investigates 20 of the new energy vehicle KTs in China and independently evaluates their performance at the technical level and their economic-social benefits. We first use uncertain linguistic variables to simulate an uncertain decision environment and more closely reflect the decision maker's thinking model; we then propose a weighting method that integrates subjective (Analytical Network Process) and objective (Entropy Weight Method) evaluations to rank the 20 KTs. Compared with conventional methods, the proposed model mitigates the adverse effects of uncertainty while providing a practicable approach that reflects the sentiments of area experts. The model is comprehensi...
