The environmental-adjusted energy efficiency of China’s construction industry: a three-stage undesirable SBM-DEA model

Abstract

Construction industry is a pillar industry of China's national economy but its problems of high energy consumption, high pollution and low energy efficiency is increasingly prominent. The study on the energy efficiency of construction industry is of great significance for improving development quality and achieving the goal of energy saving and emission reduction. In this paper, a three-stage undesirable SBM-DEA model was employed to measure the energy efficiency in construction industry during 2005 -2016. The CO 2 directly emitted by the construction industry and indirectly emitted in the production of building materials were used as the undesirable output and the three-stage framework was employed to analyze and eliminate the influence of external environment. The empirical results showed that low efficiency of management in the construction industry is an important factor leading to the low level of energy efficiency in China's construction industry. For the energy efficiency value before and after adjustment, the "high-high" provinces has made full use of the superior external environment by their high management level, while the "high-low" provinces needs to fully realize the potential in promoting energy efficiency of its external environment by improving its own management of construction industry. On the contrary, the "low-high" provinces need to improve the external environment to ease its restrictions on the level of management in the construction industry. Environmental factors and management level should be considered simultaneously for different provinces to improve energy efficiency of construction industry.

Green Total-Factor Energy Efficiency of Construction Industry and Its Driving Factors: Spatial-Temporal Heterogeneity of Yangtze River Economic Belt in China

“…The energy efficiency of the construction industry has attracted much attention from the government and academia. Promoting energy efficiency in the construction industry is the key to alleviating resource, energy, and environmental constraints, improving development quality, and achieving the goal of energy saving and emission reduction [ 2 ]. Therefore, an effective evaluation of the energy efficiency of the construction industry is necessary.…”

“…The DEA model has been widely applied to evaluate the energy efficiency or environmental performance assessment of many sectors, such as industrial sectors [ 7 , 8 , 9 ], agricultural sectors [ 10 , 11 ], energy-intensive industries [ 3 ], and so on. However, the traditional DEA model has two concerns: the disposal of undesirable outputs and the impact of external factors and random error, which promoted the evolution of the DEA model [ 2 ]. Tone extended the traditional DEA method and put forward a non-radial, non-angle SBM model, which perfectly solved the problem of undesired output [ 12 ].…”

“…Tone extended the traditional DEA method and put forward a non-radial, non-angle SBM model, which perfectly solved the problem of undesired output [ 12 ]. Chen [ 2 ] and Zhang [ 13 ] applied a three-stage undesirable SBM-DEA model to measure the energy efficiency in the construction industry of China. Subsequently, Tone improved the SBM model to the Super-SBM model because it further solved the problem of cannot ranking DMUs whose efficiency are all one [ 14 ].…”

A Hypothetical Extraction Method Decomposition of Intersectoral and Interprovincial CO2 Emission Linkages of China’s Construction Industry

“…However, these studies failed to decompose the construction sector's CO 2 emissions linkages at the various regional levels and in inter-regional trade. The characteristics of the construction sectors in all of China's provinces varies with different industrial developmental stages [44,45]. With different industrial structures, demands, and consumption patterns, it is appropriate to treat each province different to fully understand the underlying CO 2 emissions interactions with other sectors within and outside the province [45,46].…”

Aproximación a la gestión de los residuos de construcción y demolición en el área metropolitana del Valle de Aburrá

“…Esto obedece, en gran medida, a la demanda de edificaciones e infraestructuras por el incremento de la población y al aumento del nivel de ingresos en muchos países (Bilal et al, 2020;Reza Esa et al, 2017a). De este modo, el planeta se encuentra enfrentado un ritmo acelerado de agotamiento de materias primas que no va acorde con el modelo de desarrollo sostenible (Díaz-García et al, 2017;Chen et al, 2021). Paralelamente, y como consecuencia de la realización, modificación y desmonte de los desarrollos constructivos, se encuentran los residuos de construcción y demolición, llamados también RCD, con unas implicaciones muy altas para el medio ambiente (Rahla et al, 2021).…”
