1C03 Unintentional Technology Spillover between Two Sectors : Kinetic Approach

概要

Here we focus only on the attempt to measure spillovers using a kinetic concept. Technology spillovers exist and the R&D of nearby firms produce positive effects, so that firms could get large benefits from spillovers. The first purpose of this paper is to review the important factors to increase the assimilation capacity. These factors allow us to suppose that each sector is separated by different level of position in order to calculate spillover effects. The second purpose is therefore to estimate the spillover effects in terms of kinetic approach. In this paper, we simulated the model using techno-economic data sets (Japanese manufacturing sector) and were able to obtain some interesting findings and implications: a) R&D spillover is a positive and significant externality and b) institutional effect is a crucial factor to accelerate assimilation capacity. However, it should be emphasized that this approach does not consider multi dimensional interactions among sectors. With such estimates, it would be possible to compute not only the absorption and assimilation capacity but also the technology stock including technology spillover beyond its own industry's borders. We think, this kinetic approach that we proposed in this paper could suggest a practical estimating method in terms of calculating absorption and assimilation capacity using speed concept instead of using regression based approach.
