Abstract This paper measures the energy efficiency among inter-provincial data in a time span of from 2000 to 2010 by Bootstrap-DEA method . It is found that the energy efficiency value of eastern China is larger than that of western China. And the energy efficiency of all provinces in China do not show convergent tendency during time 2000 and 2008,but shows obvious convergent tendency during time 2009 and 2010. DEA efficiency value is higher than that of Bootstrap-DEA efficiency value in measuring environment energy efficiency. DEA method has obvious differences with Bootstrap method. However,with Spearman coefficient test,the order of efficiency values both from the above two methods show obvious consistency.
