Abstract :
In this paper, with DEAP Version 2.1,we analyzed the total efficiency and the scale of input-output on the basis of the statistic materials of all sorts of 18 diversified railways. The result shows that the scale efficiency of diversified railway is less than 1. Investment in fixed assets is on the high side, and profit is short. The best way to improve efficiency for 11 DEA inefficiency railway bureaus is found.
