Abstract

Japan's defense industry was limited to selling only in narrow domestic markets after World War II. Nevertheless, the Japanese defense industry has continued to grow in both qualitative and quantitative sides. In order to effectively utilize the limited industrial structure and limited research budget of Japan's defense industry, spin-on and spin-off effect is highly needed. To examine the spin-on and spin-off effect, it is necessary to examine in detail how the defense companies produce both civilian and military products at the same time. This study examines the linkage between the Japanese military industry and the private industry, in particular the spin-on-off effect, and then examines the Sumitomo Precision Products(Co., Ltd.) which produces both civilian and military products in Japan. The study was conducted in parallel with the survey and interview. As a result, This paper found that the pure cycle of spin-on and spin-off effect is an important factor in achieving innovation in technology and economic performance. Sumitomo Precision Products emphasizes the importance of the company's internal research achievements in the aircraft industry and aerospace industry. In particular, it is effectively producing the spin-on-spin-off effect that occurs in the mixed production of military and civilian products. As the interoperability between defense and civilian technologies increases, the ripple effect of technology through the mutual use of defense and civilian technologies . Sumitomo Precision Products is a company that conducts R&D investments related to advanced technology to meet the strict technical requirements of military products, while also producing private products and efficiently diversifying management. There are many suggestions for us to pursue both the advancement of the defense industry and the economic effects of corporations with limited resources.
