Description

Based on the observation made on the Japanese data of R&D expenditures, we built a dynamic model of an R&D program. In this model, the concept of the cancellation rate function was introduced and three different function types were chosen for curve fitting.By use of the non-linear least-square method, for each industry, one of the three types was selected as the best fitting type. On this basis, sectoral identification was made in terms of the dynamic characteristics of R&D activities. All the industrial sectors are classified as one of the three patterns: traditional pattern, science-based pattern and high-tech pattern.Through this exercise, high-technology industry was identified as industry which is structurally different from traditional industry and from science-based industry in terms of the dynamic nature of its R&D investment. Thus, we were able to derive several tentative policy implications which are not yet well-known and have not yet been discussed.
