基于和积法与主成分法的物流业成本控制机制研究

Study on Cost Constraint Mechanism of Logistics Industry Based on Sum-product Method and PCA

指出了从宏观视角看我国物流成本的GDP占比过高的现状,同时经过微观企业的调查发现成本冗余是造成物流企业运营效率低下的主要原因。对调查数据经过整理后首先通过和积法用调查获取指标描述物流成本约束重要性,再进一步通过主成分分析将调查归纳的影响成本指标进行研究,实证论据发现物流企业内部物流控制措施的健全与否成为物流成本控制机制的关键。

In this paper, we pointed out the current cost situalion of the logistics industry of China as well as the major causes for the low operation efficiency of the Chinese logistics enterprises. Then we applied the sum-product method and PCA to analyze the indexes influencing the cost of the enterprises and identified the key role of a sound logistics control system in the successful control of the logistics cost of the enterprises.
