摘　　要：利用2005—2016年中国20个主要沿海港口的面板数据,采用超效率数据包络分析方法测算主要沿海港口的效率值,在此基础上,研究主要沿海港口效率的收敛性。结果表明:沿海港口效率总体水平较高,但港口间的效率差异显著;沿海港口总体的效率存在α收敛、β收敛,在整体上港口效率差异呈显著缩小趋势,且效率相对较低的港口表现出追赶效应。Using the panel data of the 20 major costal ports in China during 2005 to 2016,the major costal ports efficiency is measured with the super efficiency-data envelopment analysis method.On this basis,the converging conditions of the major costal port efficiency is analysed.The results show that the overall of costal port efficiency is higher,but the efficiency level between different costal ports is different obviously;There existsαconvergence andβconvergence in the overall of costal port efficiency of the 20 major costal ports,and the gap between different ports in the overall of costal port efficiency would gradually shrink and the efficiency in backward ports is catching up with advanced ports.
