IFIP Advances in Information and Communication Technology Open Source Software: Quality Verification Empirical Study of the Relation between Open Source Software Use and Productivity of Japan’s Information Service Industries

This paper analyzes the relation between OSS (Open Source Software) use and the performance of Japanese information service industry. We first estimate the market value of OSS, an issue which only a few studies have specifically addressed. The results are then used to analyze the economic effect of OSS. Although our study has some methodological limitations regarding the calculation of the market value of OSS, we demonstrate that the economic effect of OSS is generally positive.
