Abstract: This research analyzes the effects of research and development (R&D) activities on industries' sales based on accounting information for the Japanese manufacturing sector from 2001–2017, with the aim of accurately grasping the current situation. The analytical model is based on the traditional extended Cobb-Douglas production function. By avoiding the statistical problem of endogeneity and serial correlation, a multiple regression analysis was used to understand the statistical superiority of the effects of R&D expenditure and technological spillovers on sales figures. This study also analyzes the relationship between acceptance and supply of technological spillovers in Japanese industries to understand the current state of the impact of technological spillovers. In conclusion, the effects of recent R&D activities in the Japanese manufacturing sector are low. After the 1997 Asian Currency Crisis, Japan's economic growth has declined; this study could help improve R&D activities that support economic growth in this poor growth climate.
