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 national economic development. The internal mechanical composition of the car is relatively complex. The mechanical function and performance can directly affect the quality of the car. The overall performance of the car will be directly affected by the accessories. However, there are still quality problems that cannot be ignored in the current auto parts market, which cause the overall quality and performance of the car. The performance is greatly affected, so the quality control of the auto parts market must be done well to ensure that the quality of auto parts entering the market is qualified, so as to promote the development of China's automobile industry, while protecting the basic rights and interests of consumers.

1 Analysis of the advantages and problems of the current auto parts market in China

1.1 problems in China's auto parts market

According to the analysis, in 2019, the overall automobile market experienced a major decline, the subsidies for new energy vehicles were reduced, and the country raised emission standards, which led to greater pressure on the development of my country's auto parts market. According to relevant statistical reports, in 2019, my country The annual cumulative main business income of the auto parts market was 3.6 trillion billion yuan, a year-on-year increase of 0.35, and the growth rate dropped seriously. According to the analysis of the reasons for the decline in the development of China's auto parts market, the following main problems are summarized:

(1) The auto parts market lacks a quality control system. Auto parts is a large market, and different cars have different needs for parts, so there are many kinds of auto parts in the market, and the quality control of parts is a difficult problem. Although the auto parts market in China is developing rapidly, due to the lack of original accumulation and practical experience, there are big problems in the quality control of auto parts, and some auto parts lack effective quality control, as a result, a large number of unqualified parts enter the auto parts market, which has a great negative impact on the development of the automobile industry. Under the background that the quality control system of auto parts market is not perfect, the quality problems of auto parts occur frequently, which leads to the lack of trust of vehicle enterprises in China's auto parts market, which leads to a great blow to the development of auto parts market, which is the main problem in the current auto parts market.

(2) Poor research and development capabilities in the auto parts market. R & D capability is an important content to ensure the quality of auto parts, but the current auto parts market in China as a whole is relatively lack of R & D capability, most auto parts enterprises are mainly processing and manufacturing, has not yet formed a perfect auto parts R & D system, only a small number of large auto parts enterprises have a certain R & D capability. In the absence of research and development 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 leads to problems in the development of the auto parts market without good control.

(3) lack of scientific auto parts quality testing methods. In the current auto parts market, the state has formulated a set of detailed standards and procedures for the quality inspection of auto parts. However, with the continuous changes of the overall manufacturing technology, some new auto parts are very different from traditional auto parts, but the quality inspection methods are not updated, which leads to the use of traditional inspection methods to detect new auto parts, it is impossible to effectively identify the hidden quality problems 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. It is necessary to strengthen the innovation of auto parts quality testing technology to meet the auto parts market. Development needs are the main problems 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 identify the existing quality problems. However, in the current auto parts market, some testers have insufficient professional ability or lack perfect quality control awareness, and still use a large number of traditional manual testing modes to judge whether there are quality problems in auto parts by relying on subjective experience, which leads to the failure to effectively identify the quality risks of many auto parts, A large number of substandard auto parts products enter the market, which has a great negative impact on the development of the auto industry and the auto parts market.
