基于PCA-DEA的武汉市物流业经济效率与社会效率研究

摘要

结合城市物流理论,构建了物流业经济效率和社会效率评价指标体系,通过主成分分析和函数转化公式将社会产出中的非期望指标转化为期望指标后,对武汉市2003-2012年物流经济效率和社会效率进行了实证研究.实证研究结果表明:武汉市物流业投入要素规模偏高;物流业快速发展的同时带来了较多的社会问题.%In this paper, in connection with the urban logistics theory, we built an index system for the evaluation of the economic and social utility of the logistics industry, then converted the non-expected indexes of the social output into the expected indexes using the PCA and a function conversion formula and applied it to an empirical study on the social and economic utility of the logistics industry in Wuhan for 2003 and 2012.
