摘要
从抽样设计的事前保证和事后评估两个视角,研究分层平衡样本的代表性和多目标调查问题。分层抽样不仅提高总体特征的估计效率,还可以估计层的目标特征。平衡抽样设计通过选择与目标特征相关的辅助变量,使得辅助变量的估计与总体的总量相等。将分层与平衡抽样结合构成的分层平衡抽样方法不仅实现层内样本单元的平衡,也能实现样本的整体平衡,从而能够改进层估计的稳健性。以住户调查的初级单元抽样框为例,对城镇化率采用累积平方根法进行分层,对分层平衡样本的事后评估表明,对于平衡变量而言,样本与总体结构相近,而且层内样本结构类似于层结构。进一步对总体和层的多个目标特征进行估计,相对误差在合理范围内,说明分层平衡样本对总体或者层有良好的代表性。这为国内政府多目标调查设计代表性样本提供了新的思路,弥补了国内对代表性样本和多目标调查研究的相对不足。
The representative and multi-objective survey problems of stratified and balanced samples is studied.Stratified sampling not only improves the efficiency of parameter estimation,but also estimates the target characteristics of the stratum.Balanced sampling makes the sample structure similar to the overall structure.The stratified balanced sampling method,which combines stratified and balanced sampling,not only achieves the balance of the sample units in the stratum,but also the overall balance of the samples.Taking the primary unit sampling frame of the household survey as an example,the cumulative square root method is used to stratify the urbanization rate.The empirical analysis of stratified and balanced samples shows that the sample is similar to the overall structure,and the stratified sample structure is similar to the stratum structure.The overall characteristics of multiple targets in the population and stratum are estimated,and the relative error is within the acceptable range.It shows that the stratified balanced sample has a good representation of the population or stratum,which provides new ideas for the design of representative samples in the domestic government's multi-objective surveys and makes up for the relative shortcomings of representative samples and multi-objective surveys in China.
