Total Factor Productivity of Logistics Industry Based on DEA-Malmquist Index Model

Production efficiency evaluation of logistics industry is an important basis for national policy adjustment of logistics industry. Using Deap 2.1 software and the relevant panel data obtained from the National Bureau of Statistics, this paper estimates the TFP of logistics industry by DEA-Malmquist index model. Based on the trends of TFP and its decomposition indicators, it finds out the improvement of TFP of Chinese logistics industry in the past decade is mainly driven by technological progress, and the input of Chinese logistics industry is stable both in capital input and labor input, and the resources and efficiency of Chinese logistics industry have achieved a steady match, Chinese logistics industry has basically reached the optimal scale and achieved economies of scale from 2012 to 2021. At last, this paper points out that in the future period of time when the epidemic becomes normal, Chinese logistics industry will further increase technology investment, and its TFP will usher in a huge improvement.
