Reduction Efficiency

Data Reduction Factor (DRF) and the Super Efficiency DEA (SE-DEA) model are employed to study the energy saving and emission reduction efficiency of Shanxi Province. Based on Shanxi’s 2003~2010 panel data, firstly the public factors with economic significance are selected from many input and output indices by means of DRF; secondly the efficiency values during 2003~2010 are estimated by plugging the public factors, which are nonnegative after transformation by threshold method, in the input-oriented SE-DEA model; finally the DMUs are sorted and the efficiency value and scale returns of each unit are analyzed in details.

Abstract Green building development plays an important role in improving the efficiency of carbon reduction in the construction industry and accelerating the construction industry to achieve carbon neutrality goals. Based on the dual perspective of "industrial upgrading and space overflow", this paper integrates the topic of "green building development to promote carbon neutrality in the construction industry" into the cross-study of industrial economics and spatial economics Using China's provincial panel data from 2008 to 2019, use the intermediary adjustment model to prove how green building development builds an internal green supply and demand system in the industry to promote the efficiency of carbon emission reduction in the construction industryand use the space panel Dubin model to discuss the green building Development affects the spatial mechanism and attenuation boundary of the construction industry's carbon emission reduction efficiency. The study found that green building development has a positive effect on the efficiency of carbon reduction in the construction industry. And there is a clear "center-peripheral pattern" between green building development and the efficiency of carbon reduction in the construction industry. At the same time, the impact of green building development on the efficiency of carbon emission reduction in the construction industry exists "industry-space" two-dimensional mechanism, from the industrial perspective, green building development can activate the construction market form a green supply and demand system by promoting the green upgrading of supporting industries and stimulating the green consumption of the market, and finally realize the overall green upgrading of the construction industry. from the spatial level, the development of regional green buildings forms a new growth pole and enhances the carbon emission reduction efficiency of the construction industry in the region through polarization effect, inhibits the carbon emission reduction efficiency of the construction industry in neighboring areas, and this spatial polarization effect also shows obvious spatial attenuation characteristics. In the 1,000 km, rangethe spillover effect is higher, while attenuation occurs outside the 1,000 km range. The results provide a theoretical basis and empirical evidence for the construction industry to improve the efficiency of carbon reduction and achieve industrial carbon neutrality.
