At present, the relationship between China's self-owned brand vehicle companies and parts suppliers is still far behind that of foreign advanced companies, and has not yet formed a good win-win model. The next cooperation will require more communication to establish R & D, manufacturing, The cooperation platform of sales and capital forms an upgrade of the cooperation model between the two sides and promotes the innovation and development of more sophisticated technologies. In the relationship between self-owned brands and their parts suppliers in China, the management of vehicle companies is too extensive and the sharing platform is poor. In particular, there is little communication with parts suppliers during the product development stage, and it is not possible to help parts suppliers improve their products. Shen Jun, vice president of Roland Berger International Management Consulting Co., Ltd. believes that China's own brand enterprises cannot give their suppliers explicit technical requirements, which directly leads to a gap between their products and foreign products in terms of quality and cost. If this problem cannot be solved well, it will probably affect the pace of independent brands taking the world forward. In terms of parts suppliers, companies with a foreign investment background occupy the high-end market, while domestic-funded enterprises mainly occupy the low-end market. However, due to the limited research and development capabilities of domestic-funded enterprises, they cannot promote the upgrading and innovation of the entire vehicle manufacturing industry through their own development, which restricts the development of China's auto industry to some extent. Philip Christian Eller, president of BMW China Services, said that vehicle manufacturers cannot simply pass pressure on parts suppliers. If you want to enhance the brand's competitiveness, it is necessary to cultivate the ability of suppliers and provide them with all kinds of help, including procurement, quality, technology, logistics and other important links. Suppliers of spare parts must also make sufficient efforts in technological innovation capability, quality assurance ability, cost control ability, logistics support ability, and outstanding talents cohesiveness, and stay in a neutral position in development. Zhang Ning, deputy secretary-general of the China Association of Automotive Engineers, stated: “Only when a supplier can help a vehicle company to grow, can he achieve total growth with the vehicle company and achieve sustainable development of his own company.†Oil Sump Pump,Centrifugal Slurry Pump,Battle Max Slurry Pump,Peripheral Water Pump Hebei Yongquan Pump Industry Co., Ltd. , http://www.cnsolarpump.com
