Abstract: Endogenous growth theory stressed that knowledge production was an important factor for technology change and long-run growth.R&D investment could produce new knowledge,which in turn induced new technology change and economic growth.Based on the endogenous growth theory,this paper presented an extended knowledge production function and analyzed the dynamic effect of various factors on knowledge production through the impulse response function and variance decomposition within a VAR framework.The conclusion was that knowledge stock,R&D expenditure and R&D staffs had positive effects on knowledge production,whereas the foreign direct investment and import had insignificant effects on knowledge production.Furthermore,this paper provided some political suggestions as follows: government should adopt policies to encourage private R&D investment and government R&D expenditure,as well as optimize the import structure and the foreign direct investment structure,so as to improve the efficiency of knowledge production.
