基于三阶段DEA模型的西部地区物流产业效率测度研究

Research on the Efficiency Measurement of Western Logistics Industry based on the Three Stage DEA Model

在“新丝绸之路经济带”和西部大开发战略的宏观背景下，基于三阶段DEA模型分析了2011—2014年西部地区物流产业效率水平测度结果表明西部地区的物流产业整体效率水平不高，投入和产出的效率值和前沿值存在一定差距，仍具有较大上升空间．其具体表现为：1）由于第一阶段没有将外部因素和随机因素加以控制，使得西部地区物流产业的综合效率水平被过高估计；2）分析各投入变量松弛冗余和产量不足的情况，表明过多物流投入会造成物流资源的浪费，应合理规划物流资源投入的地区及使用方案，减少物流资源的浪费；3）西部地区物流产业存在空间联动，应对区域物流内外部进行协同管理，从而带动空间均衡效应的经济协调发展．

： In the hackgrouud of ＂New Silk Road Economic Belt＂ and the western development strategy, based on the three stage DEA model to analyze from 2011 to 2014 logistics industry efficiency level in western region, the results show the efficiency of the whole logistics industry level in the western region is not high, the efficiency of input and output value and there is a certain gap between the frontier still, with larger rise space. The specific performances demonstrate ： 1） In the first stage comprehensive efficiency of logistics industry in the western region is overestimated because of external factors and random factors; 2） to analyze the lack of redundancy and output and input of variable relaxation in this situation, then show too much investments and logistics resources are wasted and should use logistics resources reasonably and according the logistics area plan to reduce waste of resources; 3） there is spatial linkage logistics industry in the western region, with regional logistics and collaborative management, so as to promote the balanced space effect of the coordinated development of economy.
