Abstract：The operational efficiency of port enterprises affects the development of logistics industry and the healthy development of national economy. In this paper，the SBM-DEA model is used to calculate the operating efficiencies of 17 listed companies in China from 2010 to 2015，and the relative efficiencies and input- output adjustment path of efficiencies of listed companies are obtained. The results show that the overall efficiencies of the listed companies in China are favorable，about half of the companies reach the optimal relative efficiency. But for the listed port companies that have not achieved the best efficiency， there is still a large space for efficiency promotion. The main reasons for the lack of optimal relative efficiency of some listed companies are as follows：first，the scale of development has been increased too fast，which exacerbated the mismatch of resource elements，and resulted in the excess capacity of the port and the loss of efficiency；second，the support ability of organization and management to the development of port enterprises is insufficient，and the low management level is difficult to meet modern port enterprises’requirements of information technology；and third，the pattern of profit-earning is single and port enterprises lack core competitiveness. By centering on the our national strategy of the Belt and Road and considering their own conditions and location advantages，the port enterprises should speed up the transformation from traditional port business to the integrated logistic service of trade，processing and bonded to realize the transformation to the intelligent port.
