Slacks-based measure (SBM)analysisVariable returns to scale (VRS)In order to break the tie of efficient decision-making units, super-efficiency data envelopment analysis is proposed to fully discriminate them. Recently, a slacks-based version of the super......
The three-stage Global Super Slacks-Based Measure (SBM) model is applied to accurately measure and scientifically evaluate the allocation efficiency of financial resources in China's higher education. Results show that:first, the true efficiency level can be revealed by eliminating the influence of ...
Slacks-based measure (SBM)super-efficiencyTone proposed a super-efficiency slacks-based measure (SBM) model, known as Super-SBM, which can't identify the efficiency of the inefficient DMU. However, the super-efficiency model for radial measure can identify both the efficiency for the inefficient ...
this additive model does not provide directly an efficiency measure in the objective function. Tone [20] augmented the additive model by introducing a slacks-based measure (SBM), in which the slack variables represent excesses in inputs and shortfalls in outputs, to identify directly the efficienc...
The slacks-based measure (SBM) of super-efficiency in data envelopment analysis (DEA) developed by Tone [Tone, K., 2002. A slacks-based measure of super-efficiency in data envelopment analysis. European Journal of Operational Research 143, 32–41] is a non-radial super-efficiency model compar...
Then, we propose an improved super-efficiency slacks-based measure DEA (SBM-DEA) model with weighting preference to evaluate the regional transport sustainability efficiency. An empirical application to measuring transport sustainability in Shaanxi province, China, during the period of 2000–2015 is ...
基于Super_SBM模型的污水厂投资效率实证分析_马乃毅
本文研究思路如下:首先,利用山东省2007-2021年的农业生产相关数据,对其农业现状进行简要分析,了解山东省农业生态发展趋势.其次,通过考虑非期望产出的三阶段全局前沿超效率SBM(Slacks-BasedMeasure)模型对各年份,各市的农业生态效率进行测算.再次,利用Tobit(受限因变量)模型分析粮经指数是否为山东省农业生态效率影响因素....

Using the super-efficiency Slacks-Based Measure (SBM) analysis method, the main agricultural pollution emissions (Chemical Oxygen Demand, ammonia nitrogen, and agricultural carbon emissions) were proposed as environmental constraints for the first time. The threshold regression model was used to measure ...
