Outline
Using the logistics index from 2010 to 2022 and the DEA-BCC (data envelopment analysis and Banker-Charnes-Cooper) model, it is found that the static comprehensive logistics efficiency in China is 0.668, which is at a low level. Using DEA-Malmquist index method to analyze dynamic logistics efficiency, the total factor productivity is 0.981, and the overall productivity is slightly reduced. Tobit regression model was used to explore the factors affecting logistics industry efficiency, among which economic development level had a significant and weak negative impact on logistics efficiency. The degree of industrial agglomeration and the level of innovation have significant positive effects on logistics efficiency. The degree of government intervention, informatization level and opening to the outside world have no significant influence on logistics efficiency. According to the research results, some countermeasures and suggestions are puts forward to improve the efficiency of logistics industry in China, that is, to improve the level of logistics service, optimize the level of resource allocation and improve the capability of technology research and development.
