| 摘 要： | 全国性的抽样调查若以各省级单位为子总体进行抽样设计,则可得到各省级单位的估计量.若各省级单位再次进行抽样,则可得到另一个估计量.利用这两个估计量构造了一个新的估计量,该估计量的精度优于这两个估计量中的任何一个.

| Abstract: | An estimate at a provincial level can be obtained if the provinces are the subpopulations for a national survey.And another estimate can also be got if the province conducts the survey again on its own.A new estimator which is superior to any of them is developed based on these two estimators. |

| Keywords: | sample survey subpopulation estimator optimization |
