| 摘 要： | 将数据包络分析方法（DEA）和主成分分析方法（PCA）结合，用投入产出比的相对有效性评价物流产业结构，并构建了DEA／PCA分析模型．以该模型为框架，分别采用DEA和PCA方法对物流产业结构进行评价与排序，然后将两方面的评价结果在由DEA和PCA组成的坐标系中直观地综合分析．可用该方法对各年的情况进行逐年评价，以做连续动态的对比和综合分析．

| Abstract: | DEA(data envelopment analysis) and PCA(primary component analysis) were combined to evaluate the structure of logistics industry in terms of relative efficiency of input and output,and a model was presented.In this model,DEA and PCA are used respectively to evaluate and sort the structure of logistics industry,and the results are analyzed intuitively in a coordinate composed of DEA and PCA results.This method can also be used annually to get continuous analysis results. |

| Keywords: | logistics industry structure data evaluation envelopment analysis primary component analysis |
