Logistics Efficiency Analysis of China's Coastal Provinces Based on DEA Model

In this paper, we use the DEA-Malmquist model in data envelope analysis (DEA) to analyze the logistics efficiency of China, Jiangsu, Zhejiang, Fujian, Guangdong, Hainan, Liaoning, Hebei, Shandong and Guangxi. The study shows that from 2011 to 2021, except for Zhejiang, Guangdong, Liaoning, Hebei and Shandong, the comprehensive efficiency of logistics in other provinces has not reached DEA effective. Dynamic analysis by the DEA-Malmquist model, shows that the efficiency increased from 2019 to 2020, but in addition to the pure technical efficiency growth from 2020 to 2021, all the rest decreased, indicating that the development of the logistics industry encountered obstacles.
