社会保险与商业保险的结合方式及保险资金入市研究

 社会养老保险与个人储蓄养老保险同属社会保障范畴,其共同目标是通过保险基金的增值,为投保人提供稳定可靠的养老保障,以确保安全度过人口老龄化高峰期。多年来,我国社会养老保险与商业人寿保险囿于立法范畴、管理体制、性质、特点、作用、范围、权利与义务关系的相异性,两者互不相融,各自发展,不利于养老保障三大支柱的建立。如今,以保险基金入市为契机,以资本市场为纽带,实现社会养老保险与商业人寿保险的协调与发展,是未来社会保障改革的基本走势。     

On quadratic prediction problems in finite populations

For a finite population and its linear model, Liu and Rong proposed a notion of optimal invariant quadratic unbiased prediction (OIQUP) and offered two methods for studying this notion, in which the first is incomplete. In this note, we mainly aim at fulfilling the first approach used by Liu and Rong by considering a transformed matrix equation set through permutation matrix techniques. Solvability of the matrix equation set, optimality of the resulting predictor, and equivalence of the representations of OIQUP, derived in this note and by Liu and Rong, are investigated in detail. In addition, an application to predicting population variance is conducted based on a simulated population.
