Data envelopment analysis has been successfully used in resource allocation ***,to the best of our knowledge,there are no allocation models proposed in the literature that simultaneously take both the global efficiency and growing potential into ***,this research aims at developing an allocation model for extra input resources,which maximizes the global technical efficiency and scale efficiency of a decision-making unit(DMU)set while maintaining the pure technical efficiency(i.e.,growing potential)of each *** this purpose,we first discuss the optimal resources required by each *** prove that the optimal inputs for the DMU are actually the inputs of some most productive scale size(MPSS).We then propose the allocation model based on the discussion on the case of one *** allocation model is illustrated using two numerical examples.

物流业是国民经济的重要组成部分，其效率的高低直接关系到社会经济的运行质量。本文采用DEA模型，根据我国29个省市、自治区2010年物流产业的投入产出数据对其效率进行了评价。评价结果显示：以北京、上海为代表的15个省市的物流业投入产出是DEA有效的；以青海、宁夏为代表的部分地区纯技术效率有效，规模效率非有效；以吉林省为代表的部分省、自治区产出不足，物流资源利用率低。为了保证数据的可靠性，揭示我国物流产业效率的动态特征，本文又依次对我国2009年、2011年的物流产业效率进行了评价，并在文末分别针对西部、中部及以江浙为代表的经济发达地区的物流产业发展提出了政策建议。

关键词： DEA 综合效率纯技术效率规模效率 DEA overall efficiency pure technical efficiency scale efficiency
