　　The chart reflects changes in domestic market share of automobiles of Chinese, Japanese and US brand in 2008 and 2009. As is shown in the chart, the market share of home～made automobile increased from 25% to 33%， almost an increase by 50%. In contrast, the Japanese～made automobile was on the decline from 35% to 25%， a decrease by nearly 50%. Meanwhile, the US～made automobiles remain stable in the market share。

　　Several factors may account for the market share change of the chart. The increase in home～made automobile market share is at least closely related to the following three factors. First, in 2009, Chinese government is enhancing favorable policies to improve domestic automobile production. Meanwhile, we can see that Geely merged with Volvo in 2009, which contributes to the increase of home～made automobile market share. Another obvious evidence we can find is that the poor after～service policy of Japanese automobile toward domestic market, which irritated us Chinese consumers. And the US market policies remain unchanged in this period。

　　In brief, the trend suggests that as long as we are improving our strategy and service, the home～made automobiles will continue to take a lion’s share of the auto～market. We look forward to that day。
