摘要：The index system of port logistics competitiveness is established. The improved DEA algorithm model is constructed based on principal component analysis method and DEA algorithm. The efficiency value of Shenzhen port logistics competitiveness from 2012 to 2016 is obtained through the model solution. The calculation results show that the input and output of Shenzhen port in 2015 and 2016 are unreasonable, and there is a waste of resources. The results are consistent with the present situation, which provides a scientific basis for the relevant departments to formulate the port logistics and economic development strategies.
