Four ports,namely Haikou Port,Sanya Port,Yangpu Port,and Basuo Port,are selected as the research objects.The data of nearly 10 years from 2013 to 2022 are taken as the basis for efficiency evaluation,and the DEA-Tobit model is used to evaluate the logistics efficiency of Hainan ports and analyze the factors influencing the efficiency.The research results show that the logistics efficiency value of Haikou Port is the highest,reaching DEA efficiency in re-cent years and having the best development.The development of Yangpu Port is progressive and getting better year by year,reaching DEA efficiency in 2022.The low scale efficiency value of Sanya Port leads to a low comprehensive effi-ciency value,and its development has been stagnant in recent years.The overall development of Basuo Port is relatively stable,but it has made more investments in port technology,and the economic benefits brought by technology are rela-tively prominent.Among the influencing factors,the total foreign trade volume of port cities has a significantly positive correlation with port logistics efficiency,and it has a relatively large impact on port logistics efficiency.The GDP of port cities is negatively correlated with port logistics efficiency,and the total population of port cities is negatively correlated with port logistics efficiency,while the fixed asset investment amount of port cities is positively correlated with port logis-tics efficiency.But none of these three correlations is significant.
