Evaluation of the efficiency of graduate schools using data envelope analysis (DEA)

the operational efficiency of the research aspect of the graduate university, as it was considered that the minimum efficiency in the characteristics of the graduate school would need to be reviewed. As a result of the analysis, in the case of the education investment model, there were only 3 schools with scale inefficiencies, but in the case of the research-centered model, 19 schools were found, and relatively large amounts of scale inefficiency occurred in the research side. Therefore, in terms of the size of the education investment model, most schools operate efficiently, but in terms of the research-oriented model, nearly half of the schools (19 schools, 45.2%) are causing inefficiency, and all 19 schools are profitable. As it is located in the congestion (IRS) section, it can be seen that the research function of graduate schools should be expanded.In the education investment model, there are 13 schools with operational inefficiencies, and 30% exist. It seems that efficient operation is needed. In the case of the research-centered model, there are 10 schools with operational inefficiencies, and in the research model, it can be seen that there are many inefficiencies not only in terms of scale but also in terms of operation.
