Analysis of input-output efficiency of science and technology in Colleges Based on DEA and Malmquist index

This paper summarizes the current research status and trends of science and technology input-output efficiency in colleges. In 31 provinces (municipalities, autonomous regions) in China, colleges were selected as research objects. Firstly, the authors constructed the evaluation system of science and technology input-output efficiency in colleges . Second, the DEA-BCC model is used to analyze the current situation of the overall science and technology input-output efficiency of various regions in China at the static level. Thirdly, the malmquist index model is used to value and analyze input-output efficiency from 2011 to 2020 at the dynamic level of time sequence. Finally, combined with the results, this paper puts forward some recommendations and research prospects, in order to provide a reference for Improving the efficiency of scientific and technological investment in colleges and promoting scientific and technological progress.
