It ranked first in China’s new energy market for 19 consecutive months in the initial stage of listing. However, with the changes in government policies and market, its competitiveness also declined. This paper comprehensively uses case analysis and literature research methods to study the marketing strategy of new energy vehicle Hongguang MINI EV. First of all, by using STP and 4P theory, the marketing status of Hongguang MINI EV was analyzed, and it was found that there were some problems in marketing, such as insufficient core competitiveness of products, difficulty in maintaining low-price marketing strategy with low profits, blind and inefficient promotional activities, too limited market positioning and relatively lagging digital marketing. Then, it provides optimization suggestions for the marketing of Hongguang MINI EV, including product improvement and product competitiveness. Promote technological upgrading, etc. In terms of price, differentiated pricing is adopted. In terms of channels, promote the development of all channels. In terms of promotion, promote digital marketing innovation;Attach importance to brand marketing;Cater to the trend of sharing economy. These optimization suggestions have a positive role in promoting Hongguang MINI EV new energy vehicles to better explore the market, maintain market share and create better performance.展开更多
