本研究在家庭權力架構下，將親子跨代的居住安排，依照同住、同鄰，以及居住距離遠近三種層次，分別由先生和妻子的立場討論其決策模式，強調居住安排在家庭成員間的集體協議過程。結果發現，兒子和女兒對於原生家庭的父母都有孝道的表現，但是夫妻之間對於自己父母和配偶父母的奉養，卻呈現清楚的權力相較。此外，手足之間對於奉養責任的分擔，以及親家彼此對於兒女媳婿的居住區位選擇，也都是權力互動的結果。顯然，夫妻對於雙方父母的奉養以及親子彼此的居住安排，並不全然基於利他主義，而是在涵蓋夫妻、雙方父母與手足權力架構下的彼此拉鋸，反映的可能是一個全面的家庭談判桌景象。本研究的發現同時提供人口老化趨勢下關於住宅、教育和福利的政策建議。

Focusing on the process of collective bargaining, the purpose of this study is to analyze parent-child living arrangement with respect to the tendency toward co-residence, neighboring and the proximity of residential areas based on the power structure within intra-and inter-household members. Although sons and daughters both show filial piety toward their natal parents, living arrangements between the couple, their parents and parents-in-laws, present evident power interactions. Furthermore, shares of responsibilities of parental living supports between the siblings, and the struggle for residential proximities among parents-in-law and children-in-law are the results of family members’ bargaining as well. It is obvious that the living arrangement between the couple and their parents of natal and in-law families, respectively, are not entirely altruistic oriented. It reflects rather an image of power interaction over the family bargaining table with the involvement of the couple, the couple’s parents and siblings all together. Findings of this study also provide insightful implications on related education, housing and welfare policies of an aging society.
