本研究關注嬰兒潮世代，探討其與老年父母、成年子女三代之間的代間支持類型，並分析影響代間支持類型之因素。運用2011年之「臺灣地區社會變遷基本調查計畫」第六期第二次調查家庭組資料進行分析，選取：1949年至1966年出生之樣本，並且「至少有一名父母存活」與「至少有一名成年子女」之嬰兒潮世代。研究發現：三代的代間支持類型，呈現出「由下奉養型」、「支持上下型」及「低交換型」樣貌。再者，成年子女的婚姻與工作狀況與嬰兒潮世代的家庭代間支持類型之關聯最爲顯著，而三代同住的居住安排則是增加了嬰兒潮世代提供老年父母支持協助的機率。

This study examined a typology of multigenerational support exchange of Baby Boomers, their aging parents and adult children. Using data from the 2011 Taiwan Social Change Survey (Round 6, Year 2, Family Questionnaire). In this study, subjects were born between 1949 and 1966, with at least one aging parent still alive and one adult child were analyzed. Latent Class Analyses was applied to develop intergenerational support types for (a) upward support, (b) support up and down, and (c) low exchange. The Baby Boomers whose adult children were single, or unemployed have a higher probability of falling into the ＂support up and down＂ type. While the Baby Boomers live with their aging parents and adult children, it increases the likelihood to become the ＂upward support＂ type.
