简介:域估计是抽样调查的研究热点之一,其核心问题是样本量问题。在实践中,域包含计划域和非计划域,若为计划域,兼顾总体和域的估计精度的抽样设计方案更有效,其中关键是域样本量分配问题。域样本量的研究方法主要有5种,包含传统的比例、最优、内曼、等量分配方法和Power分配方法。通过使用中国家庭追踪调查数据对5种方法进行比较研究。研究表明,比例、最优、内曼分配方法有助于提高总体的估计精度,当总样本量较小时,无法兼顾域的估计精度;等量分配方法能提高域的估计精度,便于域之间的比较,但降低了总体的估计精度;Power分配方法虽然略微降低了总体的估计精度,却显著提高了域的估计精度,是兼顾总体和域的估计精度的样本分配方法。

简介:时间见证成长,奋斗结出硕果。改革开放40年来,我国民营经济从小到大、从弱到强,不断发展壮大,成为改革开放的主要参与者、推动者和受益者,是社会主义市场经济的重要组成部分、企业家成长的重要平台。2018年11月1日,习近平总书记在民营企业座谈会上的重要讲话中强调,“毫不动摇鼓励支持引导非公有制经济发展,支持民营企业发展并走向更加广阔舞台”,引发了广大民营企业家热烈反响,凝聚起支持民营企业发展的广泛共识,为民营经济发展注入强大信心和动力。回顾改革开放40年来民营经济发展的生动实践,广东佛山称得上是一个典型样本。40年来,佛山发挥自身优势,率先解放思想,始终"先行一步”,自发进行了许多具有示范意义的改革探索。为深入学习贯彻习近平总书记在民营企业座谈会上的重要讲话精神,近日,我社副社长张鑫带队,邀请有关专家赴广东省佛山市进行实地考察调研,以期总结和展示佛山改革开放40年民营经济发展的实践经验。
