As an important means of transportation in modern times, the level of automobile manufacturing can reflect the strength of the country's manufacturing industry and affect the country's economic development. The internal mechanical composition of the car is more complex, the mechanical function, performance, etc. can directly affect the quality of the car, and the overall performance of the car will be directly affected by the accessories, but there are still quality problems in the current auto parts market that cannot be ignored, resulting in the overall quality and performance of the car being greatly affected, so we must do a good job in the quality control of the auto parts market to ensure that the quality of the auto parts entering the market is qualified, so as to promote the development of China's automobile industry and protect the basic rights and interests of consumers.

1. Analysis of the current advantages and existing problems of China's auto parts market

1.1 There are problems in China's auto parts market

Analysis in 2019, the overall automobile market has a large decline, the subsidy for new energy vehicles has been reduced, and the country has improved the emission standards, resulting in the development of China's auto parts market is facing greater pressure, according to the relevant statistical reports, in 2019, China's auto parts market has a total of 3.6 trillion yuan of main business income, a year-on-year increase of 0.35%, and the growth rate has seriously declined. According to the analysis of the reasons for the decline in the development rate of China's auto parts market, the following main problems are summarized:

(1) There is a lack of quality control system in the auto parts market. Auto parts is a larger market, different cars for parts demand is different, so the market in the auto parts of the variety of more, parts quality control is a more difficult problem, although China's auto parts market development speed, but due to the lack of original accumulation and practical experience, there are big problems in the quality control of auto parts, some auto parts lack of effective quality control, resulting in a large number of unqualified parts into the auto parts market, for the development of the automobile industry has a great negative impact. In the context of the incomplete quality control system of the auto parts market, the quality problems of auto parts occur frequently, which leads to the lack of trust of vehicle enterprises in China's auto parts market, resulting in a great blow to the development of the auto parts market, which is the main problem in the current auto parts market.

(2) The R&D ability of the auto parts market is poor. R&D capability is an important part of ensuring the quality of auto parts, but the current overall lack of R&D capabilities in China's auto parts market, most of the auto parts enterprises are mainly processing and manufacturing, and have not yet formed a perfect auto parts R&D system, and only a small number of large auto parts enterprises have certain R&D capabilities. In the case of lack of R&D capabilities, it is difficult to form a systematic and standardized model in the production process of auto parts, which leads to serious quality hazards in auto parts and problems in the development of the auto parts market without good control.

(3) Lack of scientific quality testing methods for auto parts. In the current auto parts market, the state has formulated a set of detailed standards and processes for the quality inspection of auto parts, but with the continuous change of the overall manufacturing technology, some new auto parts are very different from traditional auto parts, but the quality inspection methods have not been updated, resulting in the use of traditional detection methods to detect new auto parts, it is impossible to effectively identify the quality hazards of auto parts, especially in the context of the rapid development of the new energy automobile industry. The auto parts market has undergone great changes, and it is necessary to strengthen the innovation of auto parts quality testing technology in order to meet the development needs of the auto parts market, which is the main problem in the quality control of the current auto parts market.

(4) There are problems with quality control personnel. The quality control of auto parts needs to be tested by professionals to be able to identify the existing quality problems, but in the current auto parts market, the professional ability of some inspectors is insufficient, or the lack of perfect quality control awareness, still a large number of traditional manual testing mode, relying on subjective experience to judge whether there are quality problems in auto parts, resulting in many quality hazards of auto parts can not be effectively identified, and a large number of unqualified auto parts products enter the market. It has a great negative impact on the development of the automotive industry and the auto parts market.
