Abstract:	本文的研究目的即在探討在有限的R&D資源限制下，在不同產業中，R&D資源的集中與否，對於此產業中生產效率的關係。以台灣地區上市櫃公司中的製造業為研究對象，使用台灣經濟新報資料庫，選取2007年至2011年共五年的縱橫資料(Panel data)，首先使用Battese and Coelli (1995)隨機邊界模型，估計產業生產效?；接著再使用 Battese and Rao(2004)提出的共同生產函?概?，考量在不同產業間，生產力的異質性，藉以比較跨產業間的生產效率。最後，再使用集中度指標衡量各次產業研發資源的集中度。主要實證結果如下: (1)在非電子業中研發經費集中程度對於效率值成長率影響均為負。(2) 在非電子工業中，除了化學工業可以觀察到其研發經費集中程度對於效率成長為有利，在民生工業及金屬工業的實證結果中，都較傾向支持研發經費的集中對於效率的成長有負面的影響。 (3)電子業中研發經費集中程度對於效率值的成長影響不顯著，然而不同模型下顯示研發經費越集中，廠商會有較高的效率值。 The main purpose of this study is to examine how the concentration of R&D resources affects cross-industry productivity growth based on the data of Taiwanese manufacturing firms listed in Taiwan security market of the two-digit SIC industry (SIC 31) over the period 2007-2011。First, we estimate technical efficiency (TE) scores by stochastic frontier analysis. Then we use meta-frontier production function, proposed by Battese, Rao, and O’donnell (2004), to consider the fact that different manufacturing firms are operating under different environment and technology. Finally, we adopt several indices to measure R&D inequality which are then used to study the determinants of cross-industry productivity growth. The empirical evidence shows that the effect of R&D inequality on productivity growth is significantly negative in the Non-Electronic industrial firms. But even in the Non-Electronic industries, we find that the firms in Chemical industry have opposite results. On the other hand, there is positive effect of R&D inequality on the productivity of Electronic firms.
