China's power sector has received great research attention because of its large energy consumption and CO2 emissions. This study assesses the environmental efficiency and technology inequality of China's power sector from 2008 to 2017. Methodologically, this study proposes a non-radial FDH (free disposable hull) model and a super non-radial FDH mod...

According to the situation of real estate industry in different provinces and cities, the benefit is different, and the benefit of real estate industry in some regions is low. Based on the statistical data of real estate industry in various regions, this paper selects nine indicators, such as the number of enterprises, the average number of employe...

In response to the limitation of classical Data Envelopment Analysis (DEA) models, the super efficiency DEA models, including Andersen and Petersen (Manag Sci 39(10): 1261–1264, 1993)’s model (hereafter called AP model) and Li et al. (Eur J Oper Res 255(3): 884–892, 2016)’s cooperative-game-based model (hereafter called L–L model), have been propos...

Energy Efficiency
The scarcity of primary energy sources and depletion of the world’s fossil fuel reserves combined with wildly fluctuating energy prices in recent years have posed financial, cyclical, and environmental problems for European countries. These countries have a promising energy sector within the global energy markets, and measuring their technical effi...

The present paper aims to study the efficiency and flexibility of cement firms in India. Different data envelopment analysis (DEA) models have been employed to assess the efficiency of cement industry in India. Major findings of the DEA analysis suggest that 43 % firms are found to be technically efficient. Overall, the industry shows good performa...

The total potentials for improvement in the efficiency of a DMU frequently remain unrevealed by calculating radial efficiency measure by basic data envelopment analysis (DEA) models. This paper, therefore, applies a new slack model (NSM) of DEA, which directly deals with input and output slacks, to assess the efficiency of 27 public sector hospital...

The super efficiency of a vector variational inequality is considered in this paper. We show that for both the single and multiple criteria cases, a network equilibrium model can be recast as super efficient solutions to a kind of variational inequality. For the network equilibrium model with a vector-valued cost function, we derive the necessary a...

Conventional data envelopment analysis (DEA) assists decision makers in distinguishing between efficient and inefficient decision making units (DMUs) in a homogeneous group. Standard DEA models can not provide more information about efficient units. Super-efficiency DEA models can be used in ranking the performance of efficient DMUs and overcome th...
