U.S. auto parts industry employees is the number of vehicle production enterprises of 3.5 times. In recent decades, with the local auto enterprises in North America geographical layout changes and influx of foreign Zhuji Chang, U.S. spare parts production enterprises in the industry structure, production layout, and other aspects have taken place in the corresponding changes.

     U.S. suppliers and the adjustment of relations between the vehicle plant

     Historically, the U.S. vehicle production plant are most of their parts, the remaining through the annual procurement contracts, select the minimum bid of accessories suppliers. Now all this has changed, car plant manufacturers from supporting the procurement of all necessary accessories, such accessories are integrated modular form, Zhuji Chang and spare parts manufacturers for many years between the signing of the purchase contract.

     To Honda Motor Co. in Ohio, two assembly plants as an example, they distance themselves from a radius of 25 miles within the scope of the supporting manufacturers purchased at the engine, transmission, seats, and so on. Production dashboards, wheels, lights, glass, the matching exhaust system manufacturers are generally from Zhuji Chang in the 200-mile range. In recent years, in the southern United States established a number of Zhuji Chang, many focus on the production of certain parts of the enterprises by providing them with support, these enterprises are located in Zhuji Chang and adjacent supporting the production of the region, and around some of the spare parts manufacturers have Zhuji Chang Started focusing on logistics, other manufacturers will provide the accessories together, according to Zhu Jichang production processes need to carry out the order in the logistics Peihuo.

     Parts manufacturers moved south of the region

     Zhuji Chang providers in the United States with foreign investment and set up factories in the South continue to strengthen the trend. Today, the U.S. central and western regions on a national supplier of 61 percent, while the south accounted for 28 percent. And 1980, focus on the central and western regions of the United States about 69 percent of the suppliers, the southern region accounted for 19 per cent in 1980, about 59 percent of the supplier selection in the central and western regions and build factories, and about 34 percent in the choice of The southern region.

     Foreign vehicle manufacturers and parts supporting enterprises to set up factories in the South is an important reason for the trade unions factors. Foreign companies to avoid the powerful trade unions in the construction area, only 14 percent of foreign parts manufacturers employees are union members, U.S. employees and 84 percent for union members, two are in sharp contrast.
