Outline of Final Research Achievements

This research project proposed a new integrated research framework that consisted of models and indexes to examine productive efficiency, energy efficiency and environmental efficiency of firms and regional economies. To this aim, we developed new DEA (data envelopment analysis) models and proposed a new use of SFA (Stochastic Frontier Analysis) models to examine the efficiency measures and applied them to data of firms and regional economies. From the results, this research project indicated importance of efficiency evaluation of firms and regional economies, not only from a perspective of productive efficiency but also energy efficiency and environmental efficiency.
