本文旨在針對臺灣服務業之共同群聚現象進行研究與分析。首先，本文利用Ellison and Glaeser(1997)提出之產業共同群聚指標衡量臺灣服務產業之共同群聚程度，發現臺灣地區約有七成以上之兩兩配對產業屬於低度的共同群聚程度，顯示出臺灣服務產業整體而言，共同群聚現象並不算是非常的明顯。接著，進行臺灣服務產業之共同群聚現象的相關實證分析與探討。在實證結果的部分，本文發現在影響臺灣服務產業共同群聚現象的原因之中，Marshall(1920)提出之「投入產出關係」與「勞動市場匯集」的確對於產業之間共同群聚的現象存在著出正向且顯著的影響。然而，在「知識外溢效果」的部分，則呈現不顯著的結果。再者，考量Kolko(2010)提出之「資訊技術的程度」會影響到服務產業共同群聚現象的部分，本文亦得到了與文獻中一致的結果。

This thesis discusses the industrial coagglomeration of Taiwan service sectors, and provides an empirical analysis to test Marshall's theories of industrial agglomeration. First, we measure the level of industrial coagglomeration for Taiwan service sectors by adopting the index developed by Ellison and Glaeser, and find that there are more than seventy percent service industry pairs fall in the "not very coagglomerated" ranges. Next, we construct an empirical framework to exam Marshall's theories of industrial agglomeration. The results show that input-output linkage and labor market pooling both have positive and significant effects, while knowledge spillover has no significant effect on the industrial coagglomeration of Taiwan service sectors. Finally, we consider the impact of information technology on industrial coagglomeration, and we find a consistent result with the theory and empirical result developed by Kolko.
