This study provides a no-output growth model to conveniently calculate the total-factor energy efficiency (TFEE) index originally proposed by Hu and Wang (2006). The TFEE index serves as a very well-known and popular means of estimating overall energy efficiency. While many previous studies have...

In order to decrease the detrimental effects from global warming, the European Union (EU) has started to control CO2 emissions by allocating CO2 emission allowances to 25 member states. In this study we are interested about the effects of CO2 emission allowance on environmental efficiency,...

This study constructs the research and development (R&D) and operation processes as a value-chain framework, in which R&D results in the successful applications of patents. These patents are then used to generate final outputs in the operation. We introduce an empirical model extended from the...

This study develops a modified two-stage model to evaluate productive efficiency, occupancy, and catering service effectiveness of Taiwan׳s international tourist hotels. The difference between the modified and original two-stage model is that the modified two-stage model allows for multiple...

Previous studies involving environmental performance purely focus on analyzing environmental or waste treatment efficiencies. This study combines various aspects of environmental protection and establishes a non-radial network DEA approach to evaluate the performance of an environmental...

This study develops a modified two-stage DEA model based on the model of Chen and Zhu (2004) to evaluate China's agricultural efficiency and repaired efficiency (for stricken cultivated land) in a single DEA implementation. The government expenditures and the difference of various cultivated...
