Outline of Final Research Achievements

This research project compared the number of patents applied in Japan, USA, Germany, China, Korea, and Taiwan and analyzed the relationship between output of research and development (R&D) and firm performance in Japan empirically. According to the results comparing the number of the patents applied in Japan, USA, Germany, China, Korea, and Taiwan using PATSTAT database, although the most patents were applied in Japan in 1980’s, patent application in China were increasing exponentially within recent years catching up with Japan, USA, and Germany. In addition, the estimation result of firm value equation and total factor productivity equation using panel data of Japanese firms showed that a Japanese firm could improve the firm performance not by its R&D totally but by some technological areas.
