Abstract: | 本研究利用美國專利商標局(U.S. Patent and Trademark Office, USPTO)的專利資料,分析台灣、韓國與日本主要TFT-LCD廠商在1991-2006年技術創新能力的表現以及技術發展之動態變化。除此之外,更進ㄧ步藉著GMM計量方法探討影響廠商技術創新能力形成之決定因素,以及使用Tobit計量方法分析廠商技術多角化之決定因素,最後再利用相關分析瞭解廠商技術多角化與進入上游之間關係的密切程度。
本研究之主要貢獻,首先為本文的模型設定能清楚解釋廠商在TFT-LCD技術領域創新能力形成之決定因素為何。我們的實證結果顯示技術創新能力具有累積性,且無論是先進廠商或後進廠商,研發投入與外部學習行為皆是對技術創新能力形成相當重要的決定因素。而在廠商特性變數的部份可發現,在TFT-LCD技術領域裡,規模越大或廠齡越久的廠商未必具有絕對優勢的創新能力,因此這正是規模不大又較晚進入此領域的台灣面板廠商可以嘗試發展的機會之處。 其次,本研究清楚描繪廠商技術發展的動態路徑以及分析影響廠商決策之決定因素。我們的實證結果顯示,先進廠商高度的技術多角化以及後進廠商之所以選擇集中在TFT-LCD技術領域發展,主要是受到研發投入、顯示性比較優勢以及知識關聯性等因素的影響。同時,本研究亦觀察到規模越大或是廠齡越久的廠商,擁有較多的資源、經驗與技術能力進行技術多角化的發展策略。最後,本研究發現廠商的技術多角化與進入上游技術領域之間呈現極高度的正相關,顯示由於TFT-LCD產業成本結構的特性,廠商的技術將往上游的方向發展。 This thesis analyzes the performance and its dynamic change of technological innovations for major thin-film transistor liquid crystal display (TFT-LCD) firms in Taiwan, South Korea and Japan during 1991 and 2006 by use of the patenting data from the U. S. Patent and Trademark Office (USPTO). In this empirical study, I implement generalized method of moments (GMM) to examine the determinants of the firms’ technological capabilities and use Tobit model to investigate the factors driving the firms’ technological diversities. Finally, the analysis of correlation is adopted to probe the degree of the firms’ technological diversity in particular into the upstream field of TFT-LCD technologies. The potential contribution of this study is three-fold. First, it is found that the stock accumulation is critical and research and development (R&D) and external learning are two major determinants for firms in developing their technological capabilities, for both forerunners and latecomers. Advantage of age or size is not found and instead, it provides window of opportunity for the latecoming firms such as those in Taiwan entering TFT-LCD fields. Secondly, this study shows that R&D, revealed technology advantages, and knowledge relatedness are the three key factors influencing the high degree of technological diversities of forerunners and the concentration on TFT-LCD of latecomers. Age and size which imply the abundance of resources, experiences and technological capabilities encourage firms to diversify into a variety of technologies. Finally, a highly positive correlation is found between the firms’ technological diversities and their entry into upstream fields of TFT-LCD. The cost structure of TFT-LCD is conjectured to be the driver of the firms’ upstream diversification technologically. |
