Auto parts are one of the auto service industries, and are also the units that make up the whole car and the products that serve the car, collectively referred to as auto parts. A part refers to a single component that cannot be disassembled; a component refers to a combination of parts that achieve an action (or function). A component can be a single part or a combination of multiple parts.
As the foundation of the auto industry, auto parts are a necessary factor to support the sustainable and healthy development of the auto industry. In recent years, benefiting from the healthy and rapid development of the auto industry, the development scale and speed of the auto parts industry have been greatly improved.
The cost of the auto parts manufacturing industry is subject to the upstream industry and its own management level, while the parts required by the downstream auto manufacturers mainly come from fixed suppliers. The largest buyer of auto parts is the auto parts dealer, which is also the main channel for auto parts sales. Profit margins depend on the industry status, competition structure and bargaining power of parts and components companies with downstream industries.
