在汽车制造供应链上,主机厂的角色逐渐演变为系统集成者,主机厂只承担部件集成的责任,下级供应商全部由一级供应商选择和管理会降低主机厂的成本控制和技术研发能力、对市场的敏感度以及可持续发展。在汽车的研发、生产过程中,大部分增值活动发生在一级和下级供应商处,一级供应商承上启下,地位尤其重要。他们不但就某个模块给主机厂提供需要的技术,而且承担着管理下级供应商和供应链的职责。 In the automobile manufacturing supply chain, the role of OEMs evolves into system integrators, and OEMs only assume the responsibility of component integration. Sub-tier suppliers are all selected and managed by Tier I suppliers which will reduce the OEM’s cost control and R & D capabilities , Market sensitivity and sustainability. In the R & D and production process of automobiles, most of the value-added activities occur at the first and lower level suppliers, and the first-level suppliers are under the influence. The status is especially important. Not only do they provide the OEMs with the technology they need for a module, they also assume the responsibility of managing subordinate suppliers and supply chains.
