本研究旨在探討群聚的知識外溢效果，對於廠商的生產力與訂價能力有何影響。運用台灣經濟新報資料庫中2002年至2013年於竹科或南科設廠的台灣電子製造業廠商資料進行實證分析，並將外溢效果區分為同產業別內廠商間的水平外溢效果，與跨產業別間的垂直外溢效果，研究廠商於竹科或南科獲得之水平與垂直外溢效果對其生產力與訂價能力的影響。
計量模型上以Value-added Translog 形式之生產函數為模型，採用非線性估計法(Nonlinear Estimation method)進行生產力的衡量，並以De Loecker的估計方式衡量各廠商之訂價能力。實證結果發現廠商於竹科獲得的垂直外溢效果，對其生產力有正向的影響；而廠商於南科獲得之水平外溢效果，對其生產力有正向的影響效果，且南科上下游廠商間的垂直外溢效果，對其訂價能力有正面的貢獻，而竹科上下游廠商間的垂直外溢效果，對其訂價能力卻有負面的影響。

This research investigates the impact of knowledge spillovers on firm’s productivity and markup. The data we used from the TEJ database is based on the Taiwanese electronics manufacturing firms which have had the factories in Hsinchu Science Park (HSP) and Tainan Science Park (TSP) from 2002 to 2013 .Besides, we divide the knowledge spillovers into the horizontal knowledge spillovers among the firms from the same industry and the vertical knowledge spillovers among the firms from the different industry. We focus on researching the influence of vertical knowledge spillovers and horizontal knowledge spillovers come from HSP or TSP on firm’s productivity and markup.
We adopt Olley and Pakes’(1996) method to estimate the production function and recover firm’s productivity. In addition, we adopt the De Loecker’s (2012) method to estimate the markup of each company. Empirical results of this study are summarized as follows. The vertical knowledge spillovers effects positively influence HSP firm’s productivity, and the horizontal knowledge spillovers effects positively influence TSP firm’s productivity. The vertical knowledge spillovers effects positively influence TSP firm’s markup, but negatively influence HSP firm’s markup.
