| 概要 |
It has been thought that the main determinants of innovation are the appropriabilities of profits for the company that carried out the innovation and the acquisition of technological opportunities tha...t link the research and development of the company to the innovation. NISTEP conducted a survey in 1994 to clarify the actual conditions of those factors in the Japanese manufacturing industry. They also conducted a “Survey on Research and Development Activities of Firms in the Private Sector 2020” with questions that are comparable to those in the past survey. In this paper, using the data obtained from these two surveys, we analyzed the changes that occurred in appropriabilities and technological opportunities during the past quarter century and obtained the following results. First, the effectiveness of the various methods for profiting from the innovations implemented by the company has diminished, and the appropriability of profits has declined significantly. Second, the time taken by competitors to introduce a competing alternative (imitation lag) has become considerably longer. Third, while universities and public research institutions have become significantly more important as sources of information to provide technological opportunities, competitors have become less important as sources of information. These findings suggest a decline in competition among companies for innovation and new challenges for science and technology innovation policy.続きを見る
