Abstract:Supporting first-class teaching with first-class research is the internal demand for comprehensively revitalizing undergraduate education and realizing the connotative development of higher education. To this end, the input indicators for the efficiency of education through research are constructed from the two dimensions of "bringing research into the classroom" and "involving undergraduates in research projects", and output indicators are constructed from the three dimensions of training quality, innovation ability, and research interest. In order to scientifically and reasonably evaluate the efficiency of education through research, and to provide a reference for the optimization of resource allocation in universities, this paper uses the DEA-Malmquist index to measure the efficiency of education through research of 68 "double first-class" construction universities from 2014 to 2018. The study found that: in general, the total factor productivity of education through research in colleges and universities shows a trend of first decreasing and then increasing, but there are extensions of weak innovation, ineffective scale, and large gaps between universities. Among them, 2015-2016 and 2017-2018 showed convergence characteristics. In terms of different regions, the efficiency of universities in the western and northeastern regions still needs to be further improved; in terms of types, there is little gap in the efficiency of education through research among different types of universities, and there is still room for improvement in professional universities. Therefore, suggestions are made for the connotative development of scientific research and talent cultivation in universities: innovate the use of research and education resources, pay attention to the innovation of research and education systems and mechanisms; strengthen top-level design to create a well environment for research and education; pay attention to the development according to the characteristics of the university, launch a dislocation competition.
