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.
This paper fully considered the actuality of the regional logistics industry, and combined the common frontal method with the Malmquist index method to measure the productivity index of the logistics industry in ten eastern provinces and municipalities from 1995 to 2009. The results show that most of the Bohai Rim The technical efficiency of the logistics industry is closer to the common technology frontier. Except for Zhejiang, the logistics industry productivity indices of the remaining provinces and municipalities increased in different degrees, mainly due to the improvement of technical efficiency, while the improvement of scale efficiency was insignificant while the decrease of technological progress rate hindered the improvement of logistics productivity in ten eastern provinces and municipalities . The technological efficiency of the logistics industry in ten provinces and municipalities all has the catch-up phenomenon of the common technology frontier, that is, the gap between various regions and the common frontier is narrowing. Efficiency catching up is common, and only eight provinces and cities have the scale to catch up and the potential technological progress All of them have degradation performance.The test of MMPI results shows that the common frontier productivity index of logistics industry in ten provinces and municipalities can be divided into five layers (in order of size), Hebei is the first layer, Shandong, Beijing and Liaoning are the second layer, Fujian The third floor, the fourth floor in Shanghai and Tianjin, and the third in Jiangsu, Zhejiang and Guangdong ranks last.
