摘　　要：2019年山东省将沿海7市21个港区整合成为山东省沿海港口集团,山东省沿海港口一体化进程显著,港口一体化对港口生产效率的影响尚不明确。基于DEA⁃Malmquist指数方法,通过2017~2021年的山东省沿海港口的面板数据,分析青岛港、日照港、烟台港、威海港、潍坊港、东营港、滨州港在一体化后港口的生产效率变化情况;并从全要素生产率视角对以上港口效率进行分解,研究其港口生产效率变动的原因。通过计算可知,山东省沿海港口生产效率逐年提升,但核心因素是港口技术进步,而非港口资源整合要素,山东省沿海港口资源整合效果还有提升空间。In 2019,Shandong Province integrated 21 port areas in 7 coastal cities into Shandong Port Group Co.Ltd..The process of coastal port integration in Shandong Province is significant,but its im⁃pact on port production efficiency is still unclear.By using the DEA-Malmquist index method,this pa⁃per analyzes the changes in port production efficiency after the integration of Qingdao Port,Rizhao Port,Yantai Port,Weihai Port,Weifang Port,Dongying Port and Binzhou Port based on the panel data of coastal ports in Shandong Province from 2017 to 2021.From the perspective of total factor pro⁃ductivity,the above port efficiency is decomposed to study the reasons for the change of its port production efficiency.It can be seen from the calculation results that the production efficiency of coastal ports in Shandong Province has been improved year by year,mainly due to the port technology prog⁃ress instead of the port integration.The effect of coastal port integration in Shandong Province still needs for improvement.
