Why China chose transition before ¡§Open door policy¡¨? When China upgrades their innovative capabilities, do any factors affect outcomes? This study will use more macroscopic to face transition of China¡¦s technology innovation system since established PRC. To survey the institution and interaction between governments, research institutes, universities, native companies and foreign-invested companies. Finally, this study consider that China¡¦s achievement is not clearly because the shortage of talent, basic research capability between research institute is weak, government have ¡§strong control¡¨ in this system, the market mechanism is not maturity so that Chinese native companies do not have skilful in innovation.
