本篇論文建立一般化（與 Bond et al. (1994)比較）兩部門內生性成長模型，其中實質資本與人力資本之生產技術是固定規模報酬。利用傳統靜態國貿理論２Ｘ２模型的特性及結合跨期無套利條件，我們証明出在下列三種情形下(i) 0<α<1 (ii)α=1 (iii) α=0，均衡成長是馬鞍均衡穩定，要素密集度之大小不會影響這項推論。最後，我們仔細研究動態調整的過程並且討論時間偏好及支出比改變的長期效果。

In this paper, we develop a "more" (compared with Bond et al. (1994)) general two-sector endogenous growth model with constant-return-to-scale production technologies governing the evolution of physical and human capital.

　　By utilizing the properties of traditional static 2x2 inter- national trade model and combining an intertemporal no-arbitrage condition which links the capital gain on human capital to the difference between the rentals on capital and wage rate, we prove that the balanced growth equilibrium is saddle-path stable in three cases (i) 0<α<1 (ii)α=1 (iii) α=0 regardless of the factor intensity ranking.

　　Finally, we provide a detail characterization of transitional dynamics and discuss the long-run effects of changes in time pre-ference and the expenditure share,α.
