| 摘 要： | 文章运用三阶段DEA方法,实证评估了2001-2008年我国28家物流上市公司的运营效率。实证结果显示:如果对外生环境变量和随机冲击的影响不加以控制,物流企业的纯技术效率值往往被低估,规模效率值往往被高估,且高估程度大于纯技术效率被低估的程度;三阶段DEA的计算结果表明,我国物流企业的综合技术效率值较低,平均为0.668,而出现低效率主要原因是规模效率低下;物流企业规模与物流企业的效率具有显著的正相关关系,不同类型物流企业的效率存在较大差异,仓储企业的综合技术效率值最高。

| Abstract: | The Paper evaluates efficiency of 28 logistics enterprises in China during 2007-2008 with DEA three-stage model.The empirical results show that:(1) the efficiency of 28 logistics enterprises is really affected by environments and luck;(2) without controlling the exogenous environmental variables and random shocks,the pure technical efficiency of 28 logistics enterprises appears to be underestimated,while scale efficiency value is often overestimated;(3) when controlling environment factors and random error,... |
