本研究針對台灣製造業的共同群聚現象以馬歇爾三力作為基礎進行實證分析。研究中特別用勞工的教育背景以及薪資貼水捕捉產業勞動雇用的特性，並分別以有效專利數以及研發存量設計兩種指標衡量知識外溢效果。實證結果顯示，產業勞動雇用的相似性以及知識外溢的效果對於台灣製造業的共同群聚現象有正面顯著的影響。透過穩健性測試，我們認為本研究結果相當程度能夠解釋台灣製造業自民國90年到100年共同群聚程度。但礙於資料以及穩健性測試方法的侷限性，對於本研究的成果應以較為保守的態度做適當的解讀。

This paper provides an empirical analysis of co-agglomeration in Taiwan manufacturing sectors. We construct labor similarity by combing wage premium and higher education ratio. In addition, we use effective patent counts and R&D stocks to capture knowledge spillover effect. Given empirical result, we found both labor similarity and knowledge spillover have significant and positive effect on co-agglomeration in Taiwan manufacturing. After robustness check, we believe that this research in a manner provides reasonable explanation for the extent of Taiwan manufacturing’s co-agglomeration from 1991 to 2011. Due to restriction on inadequate data and imperfect methods of robustness check, we should use the result very carefully.
