Investigating interior driving factors and cross-industrial linkages of carbon emission efficiency in China's construction industry: Based on Super-SBM DEA and GVAR model

Global warming, resulted from greenhouse gases emission, has significant impacts on natural ecosystem and economic development. Construction is a leading industry in China's economy with high carbon emissions. Improving the carbon emission efficiency and investigating the driving factors of carbon emission efficiency in China's building industry are very important for the sustainable development of construction industry and the goal of China's carbon emission reduction. This paper measures the total-factor carbon emission efficiency of construction industry from 2003 to 2016 by applying Super-SBM DEA approach. Then the interior driving factors and cross-industrial shock effects of carbon emission efficiency are investigated by industry GVAR model. Empirical results show that the carbon emission efficiency in China's construction industry is low with a downward trend. With regard to interior driving factors, technological progress and energy structure adjustment can promote the carbon emission efficiency of construction industry, but the economic scale with extensive development mode exerts a certain negative influence. From the perspective of cross-industrial driving factors, economy scale, energy structure and technological progress play an important role in the carbon emission efficiency in manufacturing and electricity/gas/water industry, while relatively faint in other industries. Inter-industrial economy scale and energy structure except for transportation industry exert negative effects on carbon emission efficiency, whereas the impacts of exterior technological progress of other industries except for the mining industry are positive. In order to promote industrial carbon emission efficiency, the carbon reduction mechanism for the common but differentiated responsibilities among industries should be established.
