    摘要: 本文以台灣1987-1995年製造業中電力電子機械業小分類(three-digit)之廠商資料為實証分析對象，利用動態要素需求模型檢視R&D及其作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 者為產業間與產業內之外溢，以分析其影響之差異。實証結果發現:1.台灣高科技產業之產業間與產業內R&D外溢效果皆十分顯著，並在標本期間內有上升的趨勢；2.兩種型態之R&D外溢效果對廠商之成本結構與要素需求並未存在絕對性的影響，而是依其產業別不同而有差異；3.外生技術變動降低廠商對變動成本的需求，而增加準固定要素－資本與R&D之使用。
    This paper estimates the intra- and inter-industry R&D spillovers and exogenous technical change effects on cost structure and factor demands for the six top Taiwan high-technology industries. The empirical study is implemented using plant-level data for over 2300 plants over the period 1987-1995. Based on a dynamic factor demand model, estimates of the effects of intra- and inter-industry R&D, and exogenous technical changes on cost structure and estimates of spillover sources for Taiwan high-tech industries are obtained. The empirical evidence shows the following. 1) Both intra- and inter-industry R&D spillover effects are significant and show an increasing trend in Taiwan high-tech Indus- cries during 1987-1995. 2) The impact of R&D spillovers (both intra- and inter spillovers) on a firm`s cost structure and factor demands differs depending on industry characteristics. 3) External technical change leads to a decrease in variable costs and an increase in quasi-fixed inputs-R&D and physical capital.
