摘要: 内容摘要:本文首先介?绍了样本轮换研究问题提出的背景和国内外研究现状。接着介绍了分层抽样下样本轮换的理论模型。包括分层抽样下样本轮换的估计量公式和最优样本轮换率的确定方法。再接着利用前面介绍的理论知识,结合上海市城镇住房空置率抽样调查数据进行实证分析。由于该抽样调查采取的是分层抽样,因此相应地用分层抽样下的样本轮换研究。先根据该抽样调查本身的特点和社会经济活动的规律确定样本轮换时间间隔为1年。再分别计算出各层的最优样本轮换率和总体的样本轮换率。最后分别对三层子总体样本轮换的效果进行分析,分析发现各层经过样本轮换以后的精度比不进行样本轮换或进行完全样本轮换的精度有了明显的提高,轮换效果显著。

Abstract: Abstract:This paper introduced the research background and reviewed the theoretical model of the sample rotation, including the estimator formula and the method to compute the sample rotation rate. Based on the theory and method introduced before, this paper applied the rotation models to compute the sample rotation rate of sampling survey on vacancy rate of households in Shanghai. As the sampling survey is stratified sampling, so the research of the sample rotation is under the stratified sampling. The paper fixed the sample rotation cycle as 1 year according to the features of the survey itself and with the law of the social economy. Then the paper computed the best sample rotation rate for each stratum and the whole. Finally, the paper analyzed the effects of the sample rotation, and found the accuracy was greatly improved.
