Measurement on the Efficiency of Regional Logistics Industry under the Constraint of Low Carbon

The traditional efficiency measurement of the logistics industry does not consider the problem of dioxide emissions. This paper proposes the total factor productivity (CLP) of the logistics industry under the constraint of carbon intensity. Based on the construction of the panel data of the logistics industry in 30 provinces and regions in China from 2005 to 2012, the environmental DEA technology and the directional distance function method are applied to conduct an empirical analysis of the growth sources and regional differences of the total factor productivity of China's logistics industry under the constraints of carbon intensity. . The results show that the logistics industry's total factor productivity under the carbon intensity constraint has an average annual growth rate of 1.9%, which is higher than that without considering the carbon constraint; the logistics industry productivity index under the carbon intensity constraint is consistent with the carbon intensity target, and the logistics industry's total factor productivity has improved , The carbon intensity decreases; the improvement of logistics productivity mainly depends on the progress and innovation of logistics technology; under the constraint of carbon intensity, there is convergence in the logistics productivity of the eastern region, the difference in the central region is expanding, and the western region is shrinking.
