| Summary: | 碩士 === 國立中興大學 === 科技管理研究所 === 92 === According to a research by Taiwan Institute of Economic Research, the number of patents assigned to Taiwan was ranked in the second place of the nations in the world. Although Taiwan enjoys a good lead in the number of patents, research and development’s ability isn’t in proportion to it. In addition to the achievement in terms of patent quantity, Taiwan has to enhance its patent quality in order to gain the advantages in the knowledge economy.
This study chooses the key films of TFT-LCD industry in Taiwan, Japan and Korea. Employing the patent analysis tool, Patent Guider 1.0, retrieves their individual patent data from United States Patent and Trademark Office. The purpose of this study includes exploration of the evolution of technology innovation, linkage between R&D performance and non-patent references (NPRs), and interaction between overall performance and NPRs in TFT-LCD industry. This study employs several indicators including the number of patent, number of NPR cited, science linkage, science cycle time. This study also explores the degree of interaction between international patent classes and science subjects, which demonstrate the strongest linkage in TFT-LCD industry.
It is found that the development of NPRs preludes that of patents. Overall, Japanese firms have higher science linkage than its Korean and Taiwanese counterparts. Empirical results also demonstrate that Japanese and Korean firms have higher speed of technical innovation than their Taiwanese counterpart. With respect to science linkage, 4-digit class G02F01 is found higher propensity of science linkage in TFT-LCD industry and that sheds light to our managerial implications.
