Super-efficient SBM modelIt is of great significance to study the trends and internal differences of eco-efficiency in the Yellow River Basin for ecological protection and high-quality development of the Yellow River Basin. According to the characteristics of the Yellow River Basin in China, the ...
Traditionally, the Super-SBM model must be computed in two stages in contrast to the computation of super-efficiency in radial measures. Moreover, the super-efficiency obtained by Super-SBM might be overestimated due to the inefficient projection. In the current paper, we propose an integrated ...
The super-efficient SBM model proposed by [30] solves this problem well and has been extensively used. In addition, different from the efficiency evaluation of the general standard model, the energy consumption efficiency evaluation of the provinces along the Belt and Road should consider not only...
First, the SuperSBM model may yield weakly efficient projections such that the super‐efficiency is overestimated due to ignoring the inefficiency components. Second, in the existing integrated models, some integrated models have feasible solutions, but their scale is very large; some integr...
