Evaluation of Green Logistics Efficiency in the Yangtze River Delta Region:Based on the Analysis of Super-Efficiency SBM Model and Malmquist-Luenberger Index
Using the SBM model including unexpected output,Malmquist-Lunberger index and related indicators,this paper conducts a static and dynamic analysis of the green logistics efficiency in the Yangtze River Delta from 2011 to 2021.The results show that,on the whole,although the level of green logistics efficiency in the Yangtze River Delta is relatively high,there is still room for progress;The performance of green logistics efficiency varies among the three provinces and one city;The Malmquist-Luenberger index and decomposition indicate that the improvement in green logistics efficiency in the Yangtze River Delta is mainly due to technological progress in logistics.Based on the above results,corresponding suggestions are provide.
