中美社会物流成本与GDP定量关系研究

文中选取了2000～2012年的中美两国的社会物流成本和 GDP 等相关数据，用灰色关联分析（Grey Relational Analysis，GRA）的系统理论方法分析出社会物流成本、运输成本、保管成本和行政管理成本与GDP的内在关系。用这个定量关系代替以往的物流成本与GDP比值的对比标准，分析比较得出随着GDP动态发展的过程，社会物流成本中的某些要素出现的变化。进而提出降低我国物流成本的相关对策。研究表明：降低社会物流成本，优化物流成本结构，是我国现阶段甚至是较长一段时期内物流业发展振兴的关键所在。

The Study of Quantitative Relationship between Cost of Social Logistics and GDP in China and the United States

In this paper,some data such as GDP and the cost of social logistics from 2000 to 2012 in China and the United States have been selected,to analyze the internal relations between GDP and the costs of social logistics,transportation,storage and administrative,with a method of GRA system theory.The changes of some elements in the cost of social logistics with the dynamic development of GDP are revealed by using these relations to substitute for the previous standard of comparison,the ratio between logistics cost and GDP.Based on these findings,some related countermeasures to reduce logistics cost in China are to be put forward.Research has shown that the key to the revitalization of the logistics industry in our country at present or even for a long period is to reduce social logistics cost and to optimize the structure of logistics cost.
