A parallel-running-type growth model in Asia: A case of clean technology

A significant structural change in the pattern of economic development in Asian countries has been observed in recent years. In this situation, the existing studies on development economics, political science and innovation research cannot sufficiently explain the driving force and the mechanism of catchup or economic growth. Therefore, it is now required to model this new type of economic development. In this paper we analyzed their scientific catch-up status using the data of four fields of clean technology to clarify the structural change. The results show that, while Asian countries have received matured technologies such as energy saving from advanced countries, they are accelerating research and development activities on emerging technologies. China, Korea and Singapore have caught up with advanced countries by conducting pioneering research for clean energy technologies to support their industrial development. On the other hand India has conducted relatively path-following catch-up. International collaboration still remains among the US, EU and Japan as it has been developed over a long time. However it is now changing with the emergence of Asian countries.
