... the upper bounds for the undesirable products provide low-efficiency results in comparison with the existing model. On the other hand, the results cover the arguments of sustainability in the evaluation of environmental efficiency. Originality/value In the production process, desirable outputs...

.../approach A novel data envelopment analysis (DEA) model, based on the classical DEA theory, is developed from the perspective of emission reduction. Findings The empirical results indicate that China’s overall environmental efficiency is low and that there is huge improvement space for energy saving...

... and environmental quality associated with the use of agrochemicals. Design/methodology/approach This study uses a theory of environmental efficiency that measures how efficient the farm uses agrochemical inputs. The efficiency was estimated using a set of farm-level data of intensive farming that use...
