小微企業(yè)抽樣調(diào)查的樣本輪換

摘要： 目前,小微企業(yè)抽樣調(diào)查數(shù)據(jù)受到各級政府和社會各界的高度關(guān)注。針對小微企業(yè)單位新增、消亡變動頻繁的特點,研究了總體單位及樣本量變動的一般條件下的樣本輪換理論,對樣本輪換率和估計量進(jìn)行了探討,擴(kuò)大了研究結(jié)果的適用范圍,得到了簡單隨機(jī)抽樣、分層抽樣中樣本輪換的有關(guān)結(jié)論,對估計量的抽樣誤差進(jìn)行了有效控制,并進(jìn)行了相關(guān)實證研究,最后提出了構(gòu)造適合小微企業(yè)連續(xù)性抽樣調(diào)查的樣本輪換設(shè)計模式和方法。
At present,the sampling survey data of the small and micro enterprises has been highly concerned by the government and community of China.According to the characteristics of frequently changing about the small and micro enterprises,some new firms may come into being while a few existed ones may quit from business,so we study the sample rotation theory under the condition of population and sample size changing,and discuss the sample rotation ratio and estimator in order to expand the scope of research results.Under the general condition of population and sample size changing,we explorer sample rotation in simple random sampling and stratified sampling,and make effective control on sampling error of the estimator.At last we do some empirical research,and propose the sample rotation design and method for successive sampling of the small and micro enterprises.
