A comparative study of national innovation efficiency based on SFA
Based on the two-stage theory of innovation,this paper divides the innovation efficiency into R & D efficiency and output efficiency.Using the stochastic frontier analysis method(SFA)to evaluate and compare the innovation efficiency of the worlds major innovative countries and BRIC countries.It is found that Chinas R & D efficiency is at a low level,the output efficiency level is higher.In the empirical analysis,it is also found that foreign direct investment has no direct effect on R & D efficiency and has negative influence on output efficiency; market openness has a positive impact on R & D efficiency and output efficiency; government R & D investment has a negative impact on R & D efficiency and output efficiency.Finally,suggestions are made.
