摘　　要：港口作为国际运输的枢纽和对外经贸的支撑点,参与经济腹地资源要素分配。港口物流通过其辐射作用对相关产业产生强大的凝聚效应和拉动效应。然而,“双碳”背景下,要求传统港口运作模式向低污染、低能耗、可持续发展模式转变。文章采用基于非期望产出的Super-SBM模型与Global-Malmquist-Luenberger指数模型对2012—2021年中国沿海24个港口效率进行测度研究。研究结果表明:中国沿海主要港口的静态效率存在明显差异,港口效率都有不同程度的提高,但大多数效率低于1,仍有改善空间;沿海港口动态效率呈现“W”型的波动增长趋势;港口技术效率变动指数受资源配置及技术进步影响实现正增长。港口技术进步变动指数有明显改善,对提升整体效率作用显著。As the hub of international transportation and the support point of foreign trade and economy,ports participate in the allocation of economic hinterland resources.Port logistics has strong cohesion effect and pull effect on related industries through its radiation effect.However,under the background of"double carbon",the traditional port operation mode is required to change to the mode of low pollution,low energy consumption and sustainable development.This paper use the Super-SBM model based on non-expected output and the Global-Malmquist-Luenberger index model to measure the efficiency of 24 coastal ports in China from 2012 to 2021.The results show that there are obvious differences in the static efficiency of major coastal ports in China,and the port efficiency has been improved to different degrees,but most of the efficiency is lower than 1,and there is still room for improvement,that the dynamic efficiency of coastal ports presents a"W"-shaped fluctuating growth trend,and that the change index of port technical efficiency is affected by resource allocation and technological progress to achieve positive growth.The change index of port technological progress has been significantly improved,which has a significant effect on the overall efficiency.
