本文首先借助生产法构建了符合我国国情的港口生产效率评价指标体系,弥补了类似研究中的指标选择及统计、量化方法不完善。第二,建立了基于DEA港口生产效率评价模型,借助主成分分析法解决了指标过多的问题,并定量探讨了影响港口生产效率的主要因素,客观地评价港口生产效率。第三,对大连港等8个国内主要港口生产效率进行了实证研究,分析了影响港口生产效率的主要因素,并得出港口的生产效率值与相对排序。第四,本研究为我国港口生产效率的提高提出了有针对性的政策建议。

By using production method, a port production efficiency index system that is more scientific is establised, and existing literatures comparison with single parameter is made up. Furthemore, the port production efficiency appraisal model has built based on DEA approach. Simultaneously, by using principal component analysis method, the problem involving excessive indexes is solved and primary factors affected by port production efficiency are explored quantitatively. Then, the model's practicability is validated by adopting 8 major ports in China including the Dalian port. Finally, the suggestions for improving the productive efficiency are proposed.
