摘　　要：ITS在提高港口基础设施运行效率的同时,自身功能也需要不断发展。为科学分析港口ITS改进的内容,文章建立了ITS对港口基础设施运营作用指标体系,对各指标进行主成分分析排序,得出港口ITS的改进方向。分析结果能反映我国港口ITS发展情况,对促进我国港口基础设施管理水平有很好的指导意义。While it enhances the harbor infrastructure operating efficiency, ITS needs increasing its serviceability. For the scientific analysis of harbor ITS improvement content, this article has established the influence appraisal target system of ITS to harbor infrastructure efficiency, carries on the principal components analysis arrangement to various targets, obtains the improvement direction to harbor ITS. The analysis result can reflect our country＇ s harbor ITS development situation, have the certain instruction significance to promote the harbor infrastructure＇ s sustainable development.
