本文建構一個新古典的成長模型，討論平均每人工作時間（勞動供給）和生育率之間的關係。我們發現在某些合理的參數空間下，兩者間具有負向的關係，也符合實證文獻的結果。模型中的效用函數延續Becker and Barro (1988)和Barro and Becker (1989)的精神再加入勞動供給。而養育小孩成本的設計延續Barro and Sala-i-Martin (2004)的方式，以資源的消耗來刻畫其成本。

This paper constructs a neoclassical growth model to discuss the relationship between hours worked (labor supply) and fertility rate. We find that under some reasonable parameter spaces these two variables are negative correlated which is also in line with the result of the empirical literatures. In the model, the setting of the household’s utility function originates from the spirit of Becker and Barro (1988) and Barro and Becker (1989) with labor supply. We also follow Barro and Sala-i-Martin (2004) to assume that the cost of child-rearing is increasing with capital.
