Abstract:

Research input is the key factor of science and technology innovation. It is very significance of knowing future R&D input change trend of main sci-tech countries and international science development situation,grasping our country’s R&D input status and its contribution to science & technology development of the whole world and international influence, as well as understanding the gap between China and those science and technology developed countries,etc. Research and development ( R&D) input strength and its change,scientific papers publication which weighed basic research level,patent out which weighed application research level,and distribution of top-level scientists who have significant influence on disciplines’development in nine major sci-tech countries were analyzed in this paper. Combined with our country’s real situation, several enlightenments and suggestion were put forward about scientific & technical input and performance assessment in China.

Key words: scientific &, technological performance, R&D input, research output, quantitative analysis, major sci-tech countries
