物流上市公司经营效率评价:基于2007-2010的实证研究

用C2R-BC2模型动态评价了37家物流上市公司2007-2010年间的经营效率。研究发现总技术效率值较低,且受金融危机影响大幅下降,四年间都达到DEA有效的只有5家公司;纯技术效率值较高,几乎不受金融危机影响,四年间都达到DEA有效的有13家公司;规模效率值也较低,而且与总技术效率值呈现出一致趋势的变化,同样受金融危机影响而大幅下降,四年间都达到DEA有效的也只有5家公司;在地区差异上,西部地区和环渤海地区经营效率相对较高。因此,规模效率是决定物流上市公司经营效率的主要因素,而且物流上市经营效率受金融危机等宏观经济因素影响的程度非常大。

Evaluating the Operational Efficiency of Listed Logistics Corporations: an empirical study of 2007-2010

This paper using C2R-BC2 model to dynamically evaluate operational efficiency of 37 Chinese listed logistics corporations in light of the financial data of the period of 2007-2010.It is found that the total technical efficiency is very low because it has been going down because of financial crisis,and hence only five corporations reached EDA efficiency during 2007 to 2010.The pure technical efficiency is comparative high and thirteen corporations reached EDA efficiency during 2007 to 2010.The scale efficiency is very low,which is in accordance with the change of total technical efficiency,and hence there are also only five corporations that reached EDA efficiency during 2007 to 2010.Moreover,those in Western and around the Bohai Sea are comparatively high.Consequently,it can be drawn that it is the scale efficiency that decides mainly the operational efficiency of Chinese listed logistics corporations,and the influence of macroeconomic factors such as financial crisis is extraordinary.
