Data envelopment analysis (DEA), based on relative efficiency, is an efficiency evaluation method for the same type of decision-making units (DMU). Using sequence data of 1995-2007 and production function including the stock of knowledge, this paper chooses the VRS DEA model based on the assumption of input orientation to measure annual energy efficiency of Jiangsu in the framework of total-factor...
The traditional evaluation models of energy efficiency often only involve energy consumption and economic outputs, but neglect environmental impact of energy and substitution effect between energy and related factors. Under the frame of total factors energy efficiency, undesirable outputs and related factors about energy are considered, and then a new evaluation model of energy efficiency is established...
This paper integrates the evaluation index system of sustainable development at home and abroad and calculates the technical efficiency, pure technical efficiency and scale efficiency of the sustainable development ability of energy consumption of 30 provinces (autonomous regions) in China in 2007 with CCR, BCC, SBM, and Super-SBM models. The results show that the ability of most provinces in energy...
The scientific and reasonable measure of energy-saving potential is the foundation based on which government departments at all levels sets their energy-saving goals and make corresponding policies. With reference to the research results of other scholars, the paper gives a new definition of the energy-saving potential. The definition is expected to cancel the incomparability of industrial structures,...
In this paper, a non-parametric method based on data envelopment analysis (DEA) is proposed to measure the energy efficiency. Majority of the previous studies did not consider the pollution when measuring energy efficiency, and hence the results are partially distorted on the perspective of environment. However, this paper takes into account the undesirable factors such as waste water, waste gas and...
