对于经济效率的研究，常用的DEA方法存在模型设定上的缺陷。而将Bootstrap方法与DEA方法相结合，利用Bootstrap法模拟出来的大量数值可以弥补DEA模型小样本估计方面的缺陷。笔者利用Boot．strap—DEA法对我国2000年～2010年间省际的环境能源效率做了测度，得出我国环境能源效率值中东部地区要高于西部地区的结论。

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 efficien- cy 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 effi- ciency. 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.
