Abstract: An empirical analysis of the spatiotemporal evolution characteristics of technical efficiency and total factor productivity change of the sci-tech achievements transformation has been carried on based on DEA-Malmquist model.The results show that the comprehensive technical efficiency of sci-tech achievements increased year by year,but the efficiency in 2017 and 2018  significantly fallen compared with that in previous years,and the efficiency index was overall low.The total factor productivity change indexes of the transformation of sci-tech achievements improved overall,but there were significant regional differences,with steady increase in central and eastern China and significant fluctuations in western China.To improve the efficiency in the transformation of sci-tech achievements in local universities,it is proposed to strengthen discipline construction,make clear the positioning of sci-tech innovation,innovate the mechanism of achievement transformation,and optimize the environment for achievement transformation.

Key words: local universities, technical efficiency, DEA-Malmquist model, spatiotemporal evolution
