The automobile industry is capital intensive and technology intensive, with economies of scale and brand effects particularly prominent. The automobile industry is characterized by large output value, long industrial chain, high correlation, high technical requirements, wide employment, and large consumption drive. It is an important symbol to measure a country's industrialization level, economic strength, and scientific and technological innovation ability, and occupies an important position in the global economic development. After a long period of development, the automobile industry has become one of the important pillar industries in China's economy, playing an important role in the national economy and social development.

Auto parts are the units that constitute the whole processing of auto parts and the products that serve the processing of auto parts. From the functional perspective, they mainly include engine parts, transmission parts, brake parts, steering parts, travel parts and other categories. Among them, engine parts and transmission parts are the core parts with the most intensive technology. According to the classification of the object of use, auto parts can be divided into the parts for the whole vehicle market supplied to automobile manufacturers and the parts for after-sales service market used for automobile parts maintenance and modification. Parts processing system matching and modularization; Globalization of parts processing and procurement; The rapid transfer of parts processing industry is the current development feature of the auto parts industry.

After China's accession to the WTO, the output value of the auto parts industry has increased year by year. From the perspective of the industry development trend, auto parts are constantly changing to specialization. In terms of industrial layout, at present, China's spare parts industry has formed five major regions in terms of geographical distribution: Bohai Rim, Yangtze River Delta, Pearl River Delta, Hubei Province, and the central and western regions. The merger and integration of the auto parts industry has just begun. The regional leading enterprises have broken through the regional constraints, grown into national leaders, and sought transnational development. The continuous growth of car ownership has made it possible for auto parts enterprises to grow. Most enterprises hope to grow rapidly through mergers and acquisitions to improve their market share.

In recent years, the domestic auto parts industry has shown a rapid growth trend, and some domestic parts enterprises have greatly improved their strength. Some parts manufacturers with global competitiveness in the market segments have emerged. At present, the main problems existing in China's auto parts industry are: first, the parts industry and the vehicle industry have not developed synchronously; Second, the overall supporting capacity of domestic auto parts enterprises is not strong, and the independent development and system integration capabilities are weak, which can not keep up with the pace of vehicle development; Third, China's auto dies can not fully meet the needs of the rapid development of the domestic auto parts industry.

With the development of the automobile manufacturing industry, China's auto parts industry has grown gradually. Through technology introduction, transformation and independent research and development, the auto parts industry has ushered in a period of rapid development. Although the growth rate has declined slightly in recent years, the absolute value remains at a high level. The total output value of the auto parts industry is basically similar to the auto output, and the increase of auto output will further promote the expansion of the output value of the auto parts industry.
