晚近的內生成長理論與創新理論皆強調研究發展(R&D)具有非敵對(non-rival)與不可排他(non-excludable)的性質；因此，研究發展的投資存在某種外部性。換言之，當一廠商進行研究發展時，因技術擴散的效果可使經濟體系內其他廠商接收其成果或影響廠商之生產行為，此現象稱為研究發展之外溢效果(spillovers)。本文以台灣987 –1995年製造業中電力電子機械業小分類(three-digit)下公司之panel data為實証分析對象，利用動態要素需求模型來檢視研究發展與外溢效果對廠商生產行為與產業結構之影響；同時，本文將外溢效果區分為產業間與產業內之外溢，以分析其間影響之差異。實証結果發現：一、產業間與產業內研究發展之外溢皆十分顯著；二、外溢效果對廠商變動成本與要素需求的影響並不一定存在正面之影響；三、廠商自身研究發展對產出成長之貢獻為正，但影響程度小於外溢效果；四、外溢效果在某些產業對產出成長存在著負貢獻；五、廠商在準固定要素─研究發展與資本的動態調整速度遠高於國外之研究；五、台灣高科技產業存在著規模報酬遞增的現象。
