摘要
通过运用超效率方法对处在前沿上的物流企业进行排序和效率对比,分析了我国上市物流企业的效率变化情况;通过计算马姆奎斯特TFP指数,评价了上市物流企业效率的持续性,分析了其效率的动态变化趋势。经实证研究,得出目前我国上市物流企业效率较低,技术进步贡献率大于规模效率贡献率,从而认为物流企业在追求规模扩张的同时要增加技术投入。
Super-Efficiency DEA model solves effectively the traditional DEA model for DMU full scheduling problem,this paper attempts to use the method on China's listed logistics companies for total factor productivity and the efficiency of continuous and ongoing empirical analysis.First of all,through the use of SE DEA methods to sort and efficiency of comparative studies among logistics companie,this analyzed the efficiency of logistics enterprises in China's market changes.Then,by calculating the Malmquist TFP index,evaluation of the efficiency of logistics listed enterprises on the continuing nature of the dynamic analysis of trends in its efficiency.The empirical studies arrive at the present low efficiency of China's listed logistics enterprises,the contribution rate of technological progress and scale efficiency is greater than the contribution rate,such that the size of the logistics enterprises in the pursuit of expansion at the same time to increase the technical inputs.
