Abstract:Based on Bayesian stochastic frontier model, the paper studies the effects of Xinjiang Technology factor inputs on R D outputs, calculates the level of R D efficiency for 15 prefectures in Xinjiang; explores the reason why Xinjiang has a low technology innovation from the technological point ,then puts forward recommendations about elevating technological innovation efficiency of Xinjiang prefectures. The research shows that the contributions of R D funding to R D outputs is significant, but Scientific and technical personnel inputs is not significant; The technological innovation efficiency of Xinjiang prefectures is gradually increasing; There is significant differences in 15 prefectures in Xinjiang, and technological innovation efficiency is very low in southern of Xinjiang .
