摘要

本文主要目的是建構一個政府生產性支出進入兩部門內生成長模型的生產函數，並且討論在不同融通－消費稅融通、勞動所得稅融通、資本所得稅融通下，政府規模對經濟成長率的關係。由於無法得到解析解(Analytical solution)，所以我們用數值模擬的方式來觀察政府規模對經濟成長率的關係。
我們發現了要素的生產份額對政府規模對經濟成長率有非常大的影響，要素的生產份額會影響不同政府支出融通下的排擠效果、要素移動效果以及生產性政府支出帶來的正效果，進而影響政府規模對經濟成長率的關係。而要素的技術則是在不同政府支出融通下對政府規模對經濟成長率沒有任何影響。而我們也在資本所得稅融通下，得到政府規模不宜過大的結果。

In a two-sector endogenous growth model with productive government expenditure, this thesis quantitatively analyzes the relationship between the government size and the long-run economic growth rate under alternative financing schemes – including consumption tax financing, labor-income tax financing, and capital-income tax financing. We find that the factors that determine the growth rate effect of the government size include the crowding-out effect, the factor-movement effect, and the positive external effect generated by productive government expenditure, wherein capital intensity between the sectors plays a crucial role. We also find that a change in the total factor productivity in either of the sectors has no influence on the government size-GDP growth relationship. In the case of capital-income tax financing, it is suggested that the government size should not be too big from the perspective of long-run GDP growth
