As can be seen clearly from the chart, the market share taken by domestic car brands increased rapidly from 25% in 2008 to nearly 35% in 2009，while conversely, the market share owned by Japanese car brands dropped by 10% from 35% to 25%within one year. What's more, the market share taken by American car brands was on an upward trend, from 10% to nearly 15%.
Some driving factors that contribute to the above-mentioned changes may be summarized as follows. First, the rise of Chinese cars is of little surprise as we have seen Chinese enterprises' commitment to developing self-owned technologies, which not only free them from potential risks，but also bring them long-term benefit. Second，Japanese cars, which used to be highly praised for their outstanding quality and superior stability, are now reeling from a crisis of confidence. Last, the improvement of American cars' performance must be attributed to the smart marketing strategy employed by American sellers. They launched a lot of marketing campaigns designed specially for Chinese market, which won them applause as well as benefit.
In order to maintain the good momentum of development, domestic cars should on one hand stick to their self-independent policy, and on the other hand, learn some experiences from Japanese cars' failure and Americans' success.
