This study, using improved methodology on the basis of Jaffe's approach, focuses on the analysis of the trends in technological distance in Japanese manufacturing sectors. New approach in this paper could suggest a practical estimating method considering both horizontal and vertical distance of the input (R&D investment) and output (Make matrix) sides. By utilizing improved methodology, this paper examines the empirical evidence on the impacts of technological distance on technology spillover in 13 Japanese manufacturing sectors.
