Abstract: Using data from the 2008 Chinese General Social Survey，the article examines patterns and determinants of living arrangement of young people (aged 18-32 with at least one parent alive)，contrasting only children with non-only children. Results show that demographic characteristics，offspring demand and the only child status have significant impacts on the choice of living arrangement of the young children，while parental demand also plays a role in the choice of living arrangement of the only children. Logistic decomposition models suggest that the differences in living arrangement between the only children and the non-only children are largely a result of differences in their choice of living arrangement.Socio-demographic characteristics explain a relatively small proportion of the differences.Disadvantageous population structure in the only-child families is the major determinant of their living arrangement.

摘要： 利用CGSS2008 调查数据，对18～32岁且父母至少一方健在的青年人的居住方式进行实证研究。结论是，人口特征、子代的需求状况、独生子女属性对年轻人居住方式的选择有着直接的显著影响，亲代的需求状况则通过独生子女属性对居住方式的选择发挥作用。通过反事实法对独生子女与非独生子女的居住差异进一步分解，结论是，独生子女与非独生子女居住差异的相当大比例来源于二者选择居住方式的差异，特征差异的贡献值较小，说明独生子女家庭人口结构劣势是影响其居住安排的主要因素。独生子女群体在与父母共同居住的选择上并没有以自我为中心，而是形成一种“需求导向”的居住模式:表现为在居住方式的选择上对于需求的变化更加敏感。
