Abstract: In DEA, there are typically two schemes for measuring efficiency of DMUs; radial and non-radial. Radial models assume proportional change of inputs/outputs and usually remaining slacks are not directly accounted for inefficiency. On the other hand, non-radial models deal with slacks of each input/output individually and independently, and integrate them into an efficiency measure, cal...

Promoting carbon reduction in the construction sector is crucial to achieving China’s ‘double carbon’ target. However, due interaction of multiple factors, emission efficiency Chinese industry (CEECI) varies from province province, and path efficient CEECI not uniform. This study aims analyze combined effects factors on explore underlying logic behind formation which measures for 2018 2019 30 p...

Increased energy efficiency is one of the most effective ways to achieve climate change mitigation. This study aims to evaluate the energy efficiency of seventeen countries. The evaluation is based on an integrated method that combines the super slack-based (super SBM) model and the Malmquist productivity index (MPI) to investigate the energy efficiency of seventeen countries during the period ...

Factor allocation has an important impact on production efficiency, and this study discusses factor misallocation proposes optimized method that could improve efficiency reduce inputs. Under a multi-industry competitive equilibrium model, by introducing distortion tax represents frictions inputs (capital, labor, energy, other intermediate consumption), we define price indexes to measure set the...

OBJECTIVE The objective of this experiment was to determine apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein (CP) and amino acid (AA) in 15 sources of soybean meal (SBM) produced from soybeans from different countries and subsequently to establish equations for predicting the AID and SID in SBM based on their chemical composition. METHODS Eighteen...

Small- and medium-sized technology-based enterprises (technology-based SMEs) are an important part of China’s scientific technological development. To a certain extent, the green innovation level SMEs plays significant role in supporting overall development social innovation. Carrying out research on technology efficiency evaluations is helpful to find existing problems provide references for m...

Green development (GD) has become a new model of sustainable across the world. However, our knowledge green efficiency (GDE) in Gansu province is poor. In remedy, this study, based on panel data 12 major cities from 2010 to 2017, employed super-efficient Slack-based measure (SBM) analyze and evaluate GDE input–output perspective. Furthermore, we analyzed input redundancy output deficiency ident...

Nowadays, eco-efficiency is one of the most widely used comprehensive indicators in many fields and sectors. Understanding great significance to implement sustainable socioeconomic development for decision makers. To assess performance industrial investment, investment (EEII) constructed under perspective economic benefits, energy consumption, environmental impact this paper. Then, a new supere...

This study evaluates the impact of industrial energy efficiency on agricultural development in 31 member countries Organization for Economic Cooperation and Development (OECD) from 2015 to 2019. Using dynamic network slack-based measures (DN-SBM) total factor productivity (DN-TFP) indicators, cross-period information is used assess changes sectors. The empirical results show that sector OECD mo...

This study uses the Data Envelopment Analysis (DEA) slack-based model (SBM) and Malmquist Productivity Index (MPI) to evaluate energy efficiency based on CO2 emissions in 42 countries belonging 6 continents. First, data envelopment analysis was employed calculate scores for individually continent basis then index used examine improvement. The period chosen 2011-2020. results of this showed that...
