With the high-speed increase of China’s economy, the consumption of automobile is also becoming more and more popular；I have indicated that multinational corporations are the main participant that promote China’s automobile industry, especially after China’s entry into WTO，multinational automobile producers all over the world have landed in China and began to compete intensely. 
   The reasons why multinational corporations invest in China’s automobile industry are the vast market and increasing demand for automobiles in China in recent years，I believe that we can use game theory to analyze the behavior of multinational corporations in China；
   I have further usesd related date to analyze it’s impact on the automobile market concentration of China；indicated that the behavior of multinational corporations in China has a trait that was turning from monopolization to competition，and that is in favor of the elevation of automobile market concentration of China；
   The technological advancement and the industrial upgrade of China’s automobile industry which benefit from multinational corporations’ investment，indicated that it was obvious that multinational corporations’ investment does promote the technological level and to some degree impel the upgrade of China’s automobile industry；
   The developing environment of China’s automobile industry is not so well, in next paper I will introduce the character of two most famous ways to develop automobile industry which are used by later-developed country, that is “Brazilian model” and “Japanese-Korean model” and will make a conclusion that both ways are not fit for China, then bring forward that China’s automobile industry should acclimate the trend of globalization and make full use of multinational corporations’ investment to take an international developing stratagem.
