考虑地区技术差距的区域物流业生产率指数的研究－基于共同前沿Malmquist指数方法

Malmquist Indices Research of Regional Logistics in View of Regional Technological Gap—Based on the Metafrontier Malmquist Method

本文充分考虑了区域物流业存在技术差距的实际,将共同前沿方法与Malmquist指数方法相结合,对1995-2009年东部十省市物流业的生产率指数进行了测度.结果显示,环渤海大多数地区的物流业的技术效率更接近共同技术前沿。除浙江外,其余省市的物流业生产率指数有不同幅度的增加,主要来自于技术效率的改善.规模效率的提高不显著,而技术进步率的下降阻碍了东部十省市物流业生产率的改进。十省市物流业的技术效率都存在对共同技术前沿的追赶现象,即各地区与共同前沿之间的差距在缩小,其中效率追赶普遍存在,只有八个省市存在规模追赶,而潜在技术进步全部有退化的表现.对MMPI结果的检验发现,十省市物流业共同前沿生产率指数可以分为五层(按大小顺序),河北为第一层,山东、北京和辽宁是第二层,福建第三层,上海和天津第四层,而江、浙、粤三省位居最后.

The article calculates the productivity of logistics industry in 10 east provinces with Metafrontier Malmquist indices from 1995 to 2009. The result shows that TGR of logistics in most provinces of Circum-Bohai-Sea Region is the highest. Metafrontier Malmquist indices of 9 provinces increase except Zhejiang. The changes mainly come from the improving of TE. The change of SE is not obvious. Especially, TC hinders the improving of Metafrontier Malmquist indices. Catching up performances exist araong TE of 10 provinces and SE of 8 provinces. But PTC of 10 provinces all degradates. Statistics test results show that all provinces could be divided into five groups,etc. 1, Hebei. 2, Shandong Beijing and Liaonin. 3, Fujian. 4, Shanghai Tianjin. 5, Jiangsu Zhejiang Guangdong.
