Abstract: This article analyses firms' dynamic behaviours of patent persistence and technology proximity in innovation activities for United States, Japan, South Korea and Taiwan during 1990-2003. We find that on average, the persistency of Japanese firms in sustaining their innovative activities is stronger than US firms, while South Korean firms are more tenacious than their Taiwanese counterparts.
