According to the report of the Wall Street Journal this morning, Chinese auto parts suppliers have increased their market share in this industry while demand for auto parts in developed countries has declined. According to reports, China’s rise in the light vehicle market has become the world’s largest, making the domestic parts supplier market expand and increasing its economic scale. Suppliers in China are also constantly improving their product quality and complexity levels. At the same time, they are spending less money than before to buy already depressed companies. Sales of China's auto parts industry rose by nearly 30% between 2004 and 2008.
