According to the subdivision parts, among the traditional automobile parts, the domestic enterprises have made some breakthroughs in gearboxes and engines, but they still lag far behind the foreign enterprises in the fields of automobile electronics and so on. The power battery, motor and electronic control of new energy vehicles are relatively closed because of policy protection, and domestic enterprises have certain advantages.
