物流公司全要素生产率时空异质性研究(2007-2013)——基于DEA-Malmquist

Study on the Spatial-Temporal Heterogeneity of the Total Factor Productivity of the Logistics Company (2007-2013)HAN Jianchen1, XIA Tao2

摘要:

文章利用DEA-Malmquist指数,对样本期内我国物流公司的全要素生产率进行了实证测算,并分析了效率的时空异质性特征。通过分析,得出结论：从2007年到2013年我国45家沪深上市的物流公司全要素生产率总体呈现下降趋势；技术进步指数具有上升与下降交替的特点；各要素对全要素生产率影响力存有差异；企业之间全要素指数差异较大,其中港口型物流公司比仓储运输型物流公司高且稳定。只有提升纯技术效率,设计合理的规模,加大科研投入,提高技术能力,创造自由平等的竞争环境,才能提升物流公司的全要素生产率。

Abstract:

s:The paper investigates the efficiency spatial-temporal heterogeneity and evolution trend of the total factor productivity of the Logistics company During the period of the sample,Using DEA-Malmquist index.we can Sdraw the following conclusions: the total factor productivity of the 45 logistics companies has trended down from 2007 to 2013, in addition ,the technological progress index has a characteristic of alternates of rising and falling, there exist obvious the different influence that the each factor impact to the total factor productivity; there is a large heterogeneity among the 45 Logistics companines, that is to say , The port-logistics enterprises have higher and stabler production efficiency than storage-logistics enterprises.Only promote the technical efficiency, design the reasonable scale, increase the investment of scientific research, and improve the technical capacity, besides creat the freely and equally competitive environment, the logistics enterprise can promote the total factor productivity of logistics company.
