Abstract:

Data envelopment analysis (DEA) is the most significant method in evaluating the efficiency of scientific research in higher educational institutions. However, the existing models based on DEA fail to simultaneously consider three characteristics of scientific re-search system, i.e., the input-output lagging of scientific research, the ranking of evaluation results and the evaluators' preferences. To make up for this lack of the existing researches, we propose a combined evaluation model-lagged non-radial super-efficiency DEA model. This model integrates the Almon polynomial, the non-radial DEA and the super efficiency DEA, using the Almon polynomial to simulate the process of input-output lagging of scientific research and depending on the non-radial super-efficiency DEA to meet the high-efficiency evaluation discrimination and preference requirements. Finally, an application example is conducted based on thirty-six "985 program" universities, using multi-channels to collect data and comparative methods to verify the feasibility and effectiveness of the model. The re-sults show that:lagged non-radial super-efficiency DEA owning a good discrimination could rank all evaluation objects and its evaluating result is more accurate than the standard and non-radial super-efficiency DEA and better indicative of the lag effect of the input and out-put of scientific research. This conclusion contributes significantly to the existing scientific management theory and DEA theory, and can be used to guide the development of universities and make appropriate management policies.
