Year 2008 is the turning point of China’s economic operation. This change is under the influence of the American economy and the changes in the global economy，but what’s more important is the effect of the macroeconomic control in these years. It is reputed that the turning change in China’s economic growth in 2008 is not the result of the market regulation，but the effect of the government’s initiative regulation. As Chinese economy is of huge growth potential，moderate policy adjustment will prevent the economic growth from declining. Based on this，Chinese economy will become steadier in 2009.
