This paper explores how to promote consumer identification and acceptance of green products in the field of sustainable consumption and green marketing. Specifically, this paper examines how green factors affect consumers’ willingness to purchase new energy vehicles (NEVs) and focuses on the mediating role played by perceived price equity in this process. It is found that consumers’ green self-identity, green product experience, and green product innovation have a significant positive impact on their willingness to purchase NEVs, while perceived price fairness plays an important mediating role in this process. When consumers perceive that the pricing of NEVs is fair, they are more inclined to purchase them. Through the analysis of China’s new energy vehicle market, this paper puts forward suggestions to optimize the promotion strategy of green products from the perspective of price fairness, with a view to providing theoretical support and practical guidance for relevant enterprises. As China is the world’s number one country in terms of NEV ownership, studying its market consumption willingness not only reveals the unique characteristics of the Chinese market but also provides lessons and references for the future development of the new energy vehicle market in other countries, which is of great exemplary significance.
