Abstract: We examine the simultaneous effects of spillovers due to R&D by universities and by firms on total factor productivity in a panel of over 20,000 Japanese manufacturing plants. Estimating geographic decay functions based on the location of the universe of manufacturing plants run by R&D conducting firms and public research institutions in Japan, we find a positive influence of both private and public technologically proximate-R&D stocks, which decay in distance and become negligible at around 500 kilometers. Decomposition analyses show that declining R&D spillovers are responsible for a substantial part of the decline in the rate of TFP growth in Japanese manufacturing. The exit of geographically proximate plants operated by R&D intensive firms, which may be associated with a relocation of manufacturing activity overseas, plays a notable role in this process and is an important phenomenon in major industrial agglomerations such as Tokyo and Osaka.
