本文的主要目的是利用民國六十五年台灣戶籍登記之361個鄉鎮市區資料，探求育齡婦女分齡生育率的決定因素。分析的理論基礎是建立在新古典經濟理論推展出來的新家計經濟學，並重視人口社會學家對嗜好形成因素的觀點。生育率的解釋變數中有四個是按年齡分組，用以掌握婦女如何在生育與其他活動中分配其一生的時間。為了兼容婦女的市場工作與生育決策間可能有的相互影響，我們以聯立模型作為分析工具。

The main purpose of this study has been to ascertain the determinants of age-specific female fertility rates amocng Taiwan’s 361 local administrative areas. The New Home Economics derived from Neoclassical economic theories provided models that, modified slightly by the emphasis of the demographers and sociologists on factors formulating tastes, we apply to the 1976 Household Registration Data in Taiwan. In specifying models, we not only include four female age-specific explanatory variables which are crucial to the timing of childbearing and women's other life-cycleevents, but also frame a simultaneous equations system to allow for possible interactions between their fertility behavior and labor supply decisions.
