人口流动对家庭结构影响的统计研究

Statistical Studies on Impact of Migration on Family Structure

人口流动使完整家庭分离为结构不完整的流动家庭和留守家庭,导致家庭结构的变化,其程度需要定量分析。本文以中国家庭金融调查数据为依据分析了人口流动对家庭结构的影响。结果显示,在我国家庭结构类型中核心家庭仍然占主体地位,近半数家庭是核心家庭;三代直系家庭和一对夫妇家庭所占比重比较接近,各占约五分之一;单人户和隔代家庭比重有所上升。人口流出即家庭成员的外出使得家庭结构类型向更小更简单的家庭结构类型转变。

Complete family is separated into floating family and left-behind family with incomplete structure by migration. The degree of influence and variation mode of migration on family structure need to be realized by family structure transition matrix. In this paper,on the basis of the finance data of Chinese family,analyzing the influence of migration on family structure.The survey shows that nuclear family still plays the dominant role in Chinese family structure,which means about half of the families are nuclear families. The proportion of lineal families with three generation is close to the families with only a couple,and each constituting twenty percent. The proportion of single household and skipped generation family has been increased.Migration,that is going out of family members,makes the family type transformed into smaller one.
