According to various modules and related functions of the whole vehicle, auto parts can be divided into engine, transmission system, driving system, braking system, steering system, electrical appliances, body accessories and other categories. The auto parts industry includes not only the first-class suppliers who directly provide complete systems of components to the whole vehicle factory, but also the second-class and below suppliers who provide basic parts for first-class suppliers and various parts system manufacturers. Considering that many sub suppliers also provide products to industries other than auto parts, when studying the operation status of auto parts industry, in addition to understanding the overall situation of auto parts manufacturers, it is more necessary to understand general equipment, electrical combs, electronic equipment, expected products A comprehensive analysis and summary of the business conditions of the main distribution industries of auto parts enterprises such as metal products. Among the main industries constituting the auto parts industry, the growth rate of electrical machinery manufacturing industry and electronic equipment industry in main business income, total profit and fixed asset investment is higher than that of general equipment manufacturing industry, plastics and plastic products industry and metal products industry. In 2016, the growth rate of main business income of electronic equipment manufacturing industry reached 8.7%, and the growth rate of fixed asset investment reached 158%, indicating that the industry is still in the stage of medium and high growth. As an industry providing basic raw materials, the plastic and rubber products industry and the metal products industry are facing serious overcapacity and excessive competition. It is expected that it will be difficult to achieve growth in the short term.

The products related to auto parts in the electrical machinery manufacturing industry mainly include generators, cables, steam and gas vehicles, electricity and ground, lamps, etc., and the application scope covers multiple auto parts systems. After two consecutive years of decline, the growth rate of the electrical machinery industry showed some signs of recovery in 2016, and the growth rate in enterprise sales and industrial investment rebounded to a certain extent. From the perspective of auto parts manufacturers in the electrical machinery manufacturing industry, since the rebound speed of the downstream automotive industry is significantly higher than that of the electrical machinery manufacturing industry itself, the operation of enterprises is driven by demand and may be slightly better than the overall situation of their own industry. By the end of 2016, the number of Enterprises above Designated Size in the electrical machinery manufacturing industry had reached 23413, including 2889 loss making enterprises, The loss of the industry was 123%, down 1.3 percentage points year-on-year. In terms of enterprise operation, enterprises above Designated Size in the industry achieved a cumulative main business income of 7.34 trillion yuan in 2016, a year-on-year increase of 16%, with a growth rate of 12 percentage points over the previous year, but there is still a certain gap compared with the speed before 2015.
