Abstract
The aim of this chapter is to apply an extended DEA model – emerging from a blend of a distance friction minimization (DFM) and a Target-Oriented (TO) approach based on a Super-Efficiency (SE) model – for generating an appropriate efficiency-improvement projection model. The DFM model is able to calculate an optimal input reduction value and an optimal output increase value in order to reach an efficiency score of 1.0, even though in reality this may be hard to achieve for low-efficiency DMUs. In contrast, high-efficiency DMUs might find it easier to reach an efficiency score of 1.0 or, in the case of a Super-Efficiency DEA, a score above 1.0. The TO approach specifies a Target-Efficiency Score (TES) for inefficient DMUs. This approach can compute an input reduction value and an output increase value in order to achieve a higher TES. The abovementioned TO-DFM model will be applied to an efficiency analysis of the energy-environment interface for ten regions in Japan. The focus will be on one input cost criterion (viz., expenditures) and two output-based performance criteria (viz., electricity generation and CO2 emission). Based on an extensive database, a comparative performance analysis of ten Japanese regions under consideration will be pursued.
