Technology in a commodity production activity is interdependent with all related activities including the transactions of the intermediate raw material inputs and the intrinsic factors of capital and labor of production. The technology spillovers from interdependence are influenced by commodity production technologies and the market structure of capital and labor inputs. Technological spillovers affect not only current production, but also past technologies embedded in factor inputs from accumulated experiences. In the paper “Kuroda and Nomura” (2004), we proposed the analytical framework using input-output table, in which we can evaluate the spillover effects of the technological property among industry both statically and dynamically. The potential for technological spillovers is evaluated by dividing the total factor productivity (TFP) into static and dynamic unit TFP. We observed that recent technological innovations are driving rapid structural changes through the accumulation of knowledge stock, which are intangible fixed assets created by investments in Research and Development (R&D) and Information and Communication Technology (ICT). The accumulation of these intellectual assets, such as R&D and ICT investments, influences the production efficiency of the related production sector. We elucidate the relationship between the accumulation of intangible fixed assets and the knowledge capital services derived from these assets because of R&D investment and ICT activities, using the structure of the input-output table. We propose a theoretical framework that measures the impact of knowledge service stock accumulation through R&D and ICT investments on static and dynamic unit TFP. The previous chapter explained that growth was mainly due to the accumulation of tangible fixed assets like facilities and structures. Since the latter half of the twentieth century, there has been a shift in the Japanese economy from investment in hard productive facilities to soft utilities like R&D and ICT as intangible assets. Simultaneously, there is another consensus in the society that the Japanese economy might enter a prolonged period of stagnation in the 1990s. Therefore, the impact of this scientific and technological evolution has not been as positive in Japan as expected, especially when compared to other countries. Postwar expansion of tangible fixed capital investment is gradually changing. We must consider the recent meaning and the effect of the knowledge stock by the R&D and ICT investment deeply. We aim to measure the quantity and quality of intellectual services provided by the knowledge stock through the accumulation of intellectual assets. We also propose a methodology to measure and evaluate its impact on industries. This approach will help us understand the role of these new technological innovations in economic development and the structural changes they bring about. We propose a framework and measurement method for understanding and measuring intangible fixed capital, the stock of knowledge resulting from R&D and ICT investment. This framework allows for a systematic analysis of the structure in which R&D and ICT investment alters the productivity of an industry.
