ABSTRACT
2016, as the first year of the 13th Five-Year Plan for China's postal industry, puts forward higher requirements for the deepening reform of the industry. This paper uses the Super-SBM model to empirically analyze the input-output efficiency of the postal industry in 31 provinces of China. The results show that the overall efficiency of China's postal industry is low, and the difference in the efficiency of the postal industry in each province in 2011 and 2016 is compared. It is concluded that the overall efficiency of input and output of China's postal industry in 2016 has declined slightly compared with that of 2011. The gap between regions is significant, and the input and output efficiency is highest in the eastern region, followed by the central and western regions, and the lowest in the northeast region. In some provinces, the postal industry has problems of excessive investment and insufficient output, mainly due to the inefficient use of resources.
