Based on the model of gray relational analysis, this paper analyzed from three ingredients of logistics costs, which contained management cost, inventory cost and transportation cost. The correlation between logistics cost and GDP in both China and America was calculated and the differences of the correlation between these two aspects were found out. The correlation between total logistics cost and GDP in China is higher than that in America, and so was the correlation between transportation cost and GDP. In response to these differences in this paper, the corresponding analysis and interpretation were given in order to reduce logistics cost.
