有別於過去文獻多使用產業聚集程度衡量群聚效果，本文以廠商角度出發，以廠商在群聚區域的工廠比例衡量其所得的群聚效果。本研究資料採用1990年至2015年台灣資訊電子工業廠商的資料，參考Peter等人(2013)衡量廠商生產力的方式估計，並將資訊電子工業分為電子零組件製造業與電腦、電子產品及光學製品製造業分別估計，探討科學園區外溢效果及研究發展投資對廠商生產力的影響。另外，考慮廠商特性包括:是否購買技術、廠商規模、進入園區時間和廠齡作為延伸分析，進一步討論廠商特性是否影響外溢效果及研發投資對生產力的影響。估計結果顯示電子零組件製造業研發投資金額越高及在科學園區工廠比例越高均對生產力有正面顯著的影響；而電腦、電子產品及光學製品製造業估計結果均不顯著。

This paper examines the impact of the technology spillover and R&D investment on firm productivity in Taiwan’s electronic parts and components industries and computers, electronic and optical products manufacturing industries. By using a dataset including the public listed firms from 1990 to 2015, we find that the technology spillover and & R&D investment have positive impacts on firm productivity in the electronic parts and components industry, but there is no significant impact for firms in the computers, electronic and optical products manufacturing industry.
