本文主要探討研發投資與全球化對台灣製造業薪資結構之影響，使用行政院主計處所提供「人力資源運用調查」1998年至2012年資料。參考Mincer方程式，以三階段最小平方法及分量迴歸分析台灣製造業之薪資。除了衡量需求面對於整體製造業的薪資不均度外，實證結果顯示研發投資與對外直接投資皆產生正向顯著影響，進而提升台灣製造業的薪資不均度。
本文另外將製造業依資本密集度分為「資本密集產業」、「非資本密集產業」，欲探討全球化是否因為資本密集程度而對於薪資差異有所變化。從結果得知擴大非資本密集產業薪資差距主因是對低所得國家直接投資比例，而研發投資與對低所得國家直接投資比例皆會增加資本密集產業薪資不均度。

The purpose of this thesis is to offer an empirical investigation of the real wage differential between skilled labors and unskilled labors. The main data set for thesis comes from individual-level employee data over the period 1998-2012.Following the Mincer earnings function, we examine the impacts of R&D and globalization on labors’ earnings in Taiwan's manufacturing sector. The results show that R&D and FDI have positive significant effects on the wages of skilled labors in the manufacturing sector. It implies that R&D and globalization would increase wage inequality.
We next examine whether the effects of R&D and globalization on wage inequality vary across industries with different capital intensities. We first categorize industries in Taiwan's manufacturing sector into two groups, "capital-intensive industry" and "labor-intensive industry. We find that R&D investments would increase wage inequality in labor-intensive industry. Moreover, Both R&D and FDI investments would increase wage inequality in labor-intensive industry.
