TL;DR: In this paper, a parametric frontier approach is proposed to estimate economy-wide energy efficiency performance from a production efficiency point of view using the Shephard energy distance function to define an energy efficiency index and adopts the stochastic frontier analysis technique to estimate the index.
304 citations
TL;DR: Using meta-frontier data envelopment analysis (DEA) approach, the authors proposes a new method for measuring energy efficiency by considering the "technology gap" and analyzes it as a discrete source of energy inefficiency.
285 citations
TL;DR: A comprehensive survey of empirical studies published in 2006-2015 on China's regional energy efficiency and carbon emission efficiency assessment using DEA-type models was conducted in this paper, where the main features used in previous studies were identified, and then the methodological framework for deriving the EE&CE indicators as well as six widely used DEA models were introduced.
224 citations
TL;DR: In this paper, the authors established several efficiency models based on environmental production technology, which are capable of integrating undesirable outputs into efficiency evaluation framework, and estimated the environmental efficiency, economic efficiency, environmental-environmental efficiency and two-stage efficiency of different provinces in China by considering carbon dioxide (CO 2 ) emissions.

TL;DR: In this paper, the relationship among political connections, government subsidies and firm financial performance of wind and solar manufacturing companies is analyzed based on panel data model, and the results illustrate that government subsidies, in long and short-term, have significant positive effects on the financial performance and a government background of firm executives weakens subsidy effects.

TL;DR: The main advances regarding the use of the Choquet and Sugeno integrals in multi-criteria decision aid over the last decade are reviewed in this paper, mainly a bipolar extension of both Choquet integral and the Sugeno integral.
Abstract: The main advances regarding the use of the Choquet and Sugeno integrals in multi-criteria decision aid over the last decade are reviewed. They concern mainly a bipolar extension of both the Choquet integral and the Sugeno integral, interesting particular submodels, new learning techniques, a better interpretation of the models and a better use of the Choquet integral in multi-criteria decision aid. Parallel to these theoretical works, the Choquet integral has been applied to many new fields, and several softwares and libraries dedicated to this model have been developed.

TL;DR: In this article, a review of 144 published scholarly papers appearing in 45 high-ranking journals between 2006 and 2015 have been obtained to achieve a comprehensive review of DEA application in energy efficiency, where the selected articles have been categorized based on year of publication; author (s) nationalities, scope of study, time duration, application area, study purpose, results and outcomes.
Abstract: The main aim of this review article is to review of DEA models in regarding to energy efficiency. This paper reviewed and summarized the different models of DEA that have been applied around the world to development of energy efficiency problems. Consequently, a review of 144 published scholarly papers appearing in 45 high-ranking journals between 2006 and 2015 have been obtained to achieve a comprehensive review of DEA application in energy efficiency. Accordingly, the selected articles have been categorized based on year of publication; author (s) nationalities, scope of study, time duration, application area, study purpose, results and outcomes. Results of this review paper indicated that DEA showed great promise to be a good evaluative tool for future analysis on energy efficiency issues, where the production function between the inputs and outputs was virtually absent or extremely difficult to acquire.
414 citations
TL;DR: In this article, the authors analyzed factors that influence carbon emissions due to fossil energy consumption in China to identify key factors for policies promoting carbon emission reductions and highlighted the policy implications in terms of industrial structure and energy consumption.
407 citations
TL;DR: In this paper, the authors examined the energy efficiency performance of a sample of 71 developed and developing countries between 1990 and 2014 and found evidence of a significant positive influence of both green innovation and institutional quality on energy efficiency enhancement having controlled for some variables.
