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

This paper uses the literature data method and the logical analysis method to analyze the role of market segmentation, target market selection and market positioning in sponsorship marketing based on the STP theoretical model. It is found that sports sponsorship marketing has the characteristics of strong public welfare, high credibility and strong effect, wide object and great social response. According to the STR theoretical model-market segmentation, target market selection and market positioning, it is found that there are many misunderstandings in the market segmentation of some sponsoring enterprises, the choice of target market is broad, and the market positioning is inconsistent with the content expressed by related sports events, which cannot achieve the expected purpose of sponsoring enterprises. It is proposed to sponsor companies to accurately segment the market and clarify the company’s audience goals;we should focus on the choice of target market and make rational use of limited resources;to be sponsored by the choice, we must grasp the high correlation between the event brand and the corporate brand, and strengthen the market position. Through the comprehensive use of these strategies, in order to achieve the maximization of brand value in the sponsorship marketing of large-scale sports events and win the market competition.展开更多
