Yokura, Yutaka, Sato, Masashi

This study interrogates structural changes in industrial clusters by applying the innovation ecosystem approach and demonstrates the evolution of industrial clusters in Hamamatsu, Japan, in terms of intra- and inter-regional networks and policy support for innovation. In Hamamatsu, the industrial cluster has transformed owing to the application of advanced technologies in the medical and optical industries, whereas transport, machinery, and musical instruments are basic industries. The study notes that the factors contributing to this transition include positioning Hamamatsu as a research and development basis for core companies, the development of new fields through spontaneous research networks among small and medium enterprises in the area, and technical support from universities and public research organizations. The study uses mixed methods with secondary data for quantitative analysis and primary data through interviews with respondents from selected companies. The findings show that dense intra-regional networks facilitate cooperation between industry and academia, whereas inter-regional networks serve as knowledge and information pipelines. Furthermore, the study concludes that political support underpins regional innovation in terms of finance and technology, augmenting the government’s role in the industrial network. Thus, the innovation ecosystem notion is valid in advancing empirical research on regional innovation systems.
