original appeal: cultivating its own brand. Many well-known companies have also demonstrated this process, such as BYD, which was established in 1995. After forming product design and preliminary research and development capabilities, it gradually turned to ODM. The company has completed upgrading in terms of technology and products. The transformation from ODM to OBM is reflected in business development, from OEM mobile phone sms marketing service parts to providing mobile phone assembly and design for Nokia, Motorola and other customers, as well as independent research and development of series of cars. The most important thing is to create a well-known auto brand. For e-commerce platforms, factory capacity is not a barrier. A factory can serve multiple e-commerce platforms at the same time.

Therefore, the competition between factories and e-commerce companies is a competition of quality, a competition of users' mental preemption speed, and a competition of marketing ability.
