摘 要
本研究探討在不同的生命週期階段,資本市場對各期企業經核准專利權數與企業經營績效是否有不同評價;本文同時探討民國八十三年專利法大修前後,市場對於擁有專利權數不等的公司,其所認定價值是否不同;復檢測生命週期、法規大修、與專利權之間是否存在交互的加項效果;最後觀察專利權數的多寡是否會影響到公司的股權集中度。本文使用Anthony and Ramesh (1992)的方法尋求生命週期的替代變數。實證結果發現,專利權與經營績效之間呈現顯著的正向關係,考慮不同的生命週期階段後,發現成長期的總專利權數對於經營績效的影響大於成熟期及衰退期。專利法法規大修以後,擁有愈多(沒有)專利權的公司,經營績效愈高(低),且法規大修後、處在成長期的公司,每一個專利權的邊際價值高於其他各組。最後,專利權愈多的公司,股權有愈集中的現象。
Abstract : The objective of this study is to explore whether the market response to patent would differ for a differential stage in a firm’s life cycle. We partitioned our samples into various life cycle portfolios based on methods developed by Anthony and Ramesh (1992) in order to test the hypothesis that the earnings response coefficients of firms’ patent would be greater for the growth as opposed to the stagnant portfolios. Consistently, we documents that a montonic decline in the response coeffidients of patent from the growth to the stagnant stages. Furthermore, the findings also indicate that the investors value positively (negatively) for firms with more patent (without patent ) after the enforcement of new patent regulation. Finally, firms with greater concentration in ownership appear to be with more patent
