Abstract:Competitiveness in science and technology is an important measure of science and technology, through science and technology input, output and efficacy . Select 13 division in 2012, the xinjiang production and construction corps as the research object, build three layers of 24 indicators, to determination of corps of competitiveness index in science and technology, and carries on the sorting, draw the conclusion: the eighth division, the construction division and the first division are the top division, which index above 100;the ninth division is the last one, which index is 46.61. Finally on the basis of calculation results, we suggest three aspects countermeasure from input ,output and efficacy, in order to promote corps competitiveness in science and technology to provide reference.
