Abstract: This paper provides a methodology comparing the structures of the R&D innovation processes of nations. R&D is regarded as an integrated process of three research phases: basic research, applied research, and development research. The levels of R&D activities of nations are expressed by the intelligence stocks, which are defined as the accumulated R&D expenditures of each research phase. We obtain the intelligence stocks of basic research, applied research and development research, and we investigate the structure of the R&D innovation process through an analysis of the mutually dependent structure of the intelligence stocks. We estimate the system matrices representing the interdependent structures of the intelligence stocks of the USA and Japan respectively, and compare the specific features of the R&D innovation processes of both nations, such as R&D growth capability and growth structure, by means of the eigenvalues and eigenvectors of those estimated system matrices.
Keywords: research and development; innovation processes; R&D expenditures; USA; United States; Japan; dynamic modelling; basic research; applied research; development research.
