A group of new car-making forces have emerged in the new energy vehicle industry. As a new entrant in the new energy automobile industry, Xiaomi Auto has great advantages in terms of user base, supply chain management and brand image. However, with the increasingly fierce competition in the new energy automobile industry, Xiaomi Auto is facing great challenges in marketing, which also reveals that Xiaomi Auto has some problems in marketing. In order to help Xiaomi Auto seize a larger market share also for other new car-making forces to provide upward development reference, this paper combined with the 4P theory from a micro point of view to analyze the marketing problems of Xiaomi Auto, mainly in the insufficient production capacity and delivery capacity, imperfect after-sales service, technology substitution risk, and so on, and put forward relevant recommendations for these problems.展开更多
