Sustainable efficiency and CO2 reduction potential of China’s construction industry: application of a three-stage virtual frontier SBM-DEA model
نویسندگان
چکیده
In this paper, a new three-stage virtual frontier SBM-DEA (Slacks-Based Measure of Efficiency in Data Envelopment Analysis) model is proposed to evaluate the sustainable efficiency construction industry. The relevant industry data 30 Chinese PARs (provincial administrative regions) from 2011 2016 are brought into calculate each region and verify rationality model. order solve problem that values multiple effective decision units cannot be differentiated traditional DEA evaluation, reference unit set evaluation respectively different sets SBM-DEA, two can distinguish among DEA. analysis results show average eastern, middle western China exhibit decreasing trend, at 0.643, 0.586 0.4830, respectively. Moreover, technical equipment rate external environmental factors play an important role CO2 emission reduction potential most shows downward trend.

This article modifies the conventional two-stage DEA model to construct an analytical model for energy-related efficiency with undesirable outputs. Our proposed model relaxes the constraint that the inputs of the second process must come from the first process. As a result, our proposed model is more flexible than the original model in terms of the application of energy-related efficiency measu...
