Abstract:	近三四十年來，勞動所得份額已經脫離穩定的狀態而呈現明顯下降的趨勢，同時所得分配不均的問題也日漸嚴重。投資的技術進步被認為引發這兩個現象的主要因素之一，但是既有的文獻都指出這個論點要成立必須在資本與勞動替代彈性大於1的情況下。然而，實證資料顯示，資本與勞動的替代彈性不止小於1，而且還有逐漸下降的趨勢，那麼技術進步是否仍然能用來解釋這兩個現象呢?據此，本計畫將試圖建構一個包含要素所得組成與所得分配不均的動態均衡模型，藉此探討在公共建設支出能同時帶動資本與勞動擴張技術的進步的情況下，政府的財政政策對要素所得分配與所得分配不均的影響，勞動與資本的替代彈性大於1的限制是否能被放寬；同時我們也將檢視要素所得分配與所得分配不均兩這之間的關聯性是否為單調固定。 In recent decades, the labor income share has deviated from a fixed level and decline. At the same time, income inequality has become increasingly. The existing literature pointed out that the investment-specific technology change is the main factor to triggering these two phenomena, if the substitute elasticity between capital and labor is greater than one. However, empirical data shows that the elasticity of substitution between capital and labor is less than one. Under this situation, can IST change still explain these two phenomena? In this project, we assume that the government infrastructure can bring capital-augmenting and labor augmenting and these two are different, and I will explore that the fiscal policy on how to affect the factor income share and income inequality. Finally, I will investigate the relationship between factor income share and income inequality.
