Logistics Efficiency and Dynamic Trend Analysis Under Constraints of Energy Saving and Emissions Reducing: Case Study of Three Major Economic Circles in China
After Copenhagen conference, carbon revolution has been globally rising, the concept of low-carbon logistics has been the hot spot in logistics industry at present. The paper is based on low-carbon logistics and national energy saving and emissions reducing policy and introduces environmental constraints (carbon emission and energy consumption) to construct input-output index system. Using the data of three major economic circles (Bohai Rim, the Yangtze River Delta and the Pan-Pearl River Delta) in China from 2008 to 2012 as empirical objects, the paper analyzes the logistics efficiency and energy saving potential using ultra-efficient CCR-DEA model and does the dynamic trend analysis by Malmquist Index. The results show that the logistics efficiency of the Pan-Pearl River Delta economic circle is significantly lower than the Bohai Rim and the Yangtze River Delta economic circle. It has huge energy saving potentials and should accelerate its technological progress.
