Evaluation of the logistics cost of cities based on DEA model

The effective reduction of the logistics cost of urban logistics system is the basic factor for its sustainable development. And the comprehensive evaluation for the logistics cost is the premise of its realization. The data envelopment analysis model is introduced to evaluate the logistics cost based on the input-output matrix and to provide an approach of evaluating the degree of logistics cost among the various cities. And then, the conditions of six different cities are taken for example to conduct evaluation and corresponding suggestions are put forward.
