Abstract The Paper evaluates efficiency of 28 logistics enterprises in China during 2007-2008 with DEA three-stage model. The empirical results show that: (1) the efficiency of 28 logistics enterprises is really affected by environments and luck; (2) without controlling the exogenous environmental variables and random shocks, the pure technical efficiency of 28 logistics enterprises appears to be underestimated, while scale efficiency value is often overestimated; (3) when controlling environment factors and random error, the average technical efficiency value of 28 logistics enterprises is 0.668, which is mainly due to low scale efficiency; (4) there is a significant correlation between logistics enterprises size and efficiency of logistics enterprises, and the efficiency of different types of logistics enterprises is different.
