基于SEM的港口集疏运系统影响因素研究

摘要

港口集疏运系统的影响因素是复杂而又相互关联的,分析各因素之间的影响程度有利于辨识系统结构.文章以我国沿海主要港口为样本,通过定性与定量相结合的方法,采用结构方程模型(SEM)对港口集疏运系统影响因素进行分析.通过数据分析及专家打分得出基础数据,利用AMOS软件绘制出其路径模型图,计算出其路径系数,进而分析得出主要的影响因素.%The influential factors of collecting and distributing system for port are complex and interconnected,and the analysis of influential degree between factors is helpful to identify the system structure.In this paper,a case study was made of some major ports in China's coastal areas.With both qualitative and quantitative methods,the Structural Equation Model (SEM) was adopted to analyze the influential factors of collecting and distributing system for port.The basic data was obtained from professional analysis and expert estimation,and these model diagrams were mapped out with the AMOS software.Finally the main influential factors were identified.
