	abstract = {The usage of Open Source Software (OSS) has been extended in a
wide range of business fields not only IT industries. Behind this
current situation, there are tremendous inputs by the volunteer
engineers in the development communities. In this series of
studies, we have conducted questionnaire survey to Japanese IT
companies in 2012 and 2013, and then analyzed the relation
between OSS utilization and development contribution, and how
these affect the business growth. Our study revealed that Japanese
IT companies are rather free riders of OSS, the volume of
development contributions are far less than that of utilization.
From our previous studies, it was anticipated that some OSSrelated
factors were affecting the business growth; however, clear
evidence has not been found. In autumn 2014, we conducted the
questionnaire survey for the third time and this paper presents the
survey results as the second report of the continued research. We
constructed the simplified Logistic Model to investigate the
influential factors on business growth. However, no clear
evidence was found as the same as the previous study. In
summary, we conclude that there are some form of relationships
between OSS utilization and development contribution, but these
are not the determinant factors on the business growth in the
Japanese IT companies at present. },

To analyze how OSS effects business growth both through simple use and by deeper engagement as a stakeholder in OSS community, we did questionnaire research to Japanese IT companies in 2012 and 2013. We analyze the progress of utilization and contribution of OSS, and the impact on business growth indicators by them.

The expanded use of Open Source Software (OSS), and the expansion of the market caused by this adoption has led to a corresponding increase in the number of businesses acting as stakeholders in the field. Some of these are pure users of OSS technology but a great number are developers of such technology, and can be understood to have a substantial investment in this paradigm. It is reasonable to assume that such businesses are rational actors, and that their investment or contribution to the field implies a positive economic benefit either currently obtained or assumed as a return in the future. This paper analyzes how OSS affects Japanese IT companies{\textquoteright} business growth both through simple use and by deeper engagement as a stakeholder in OSS community. This is the first time that such a link between the utilization of OSS and economic growth has been explored in the context of Japan, and it can hopefully lay a foundation for further study regarding the real economic value of this approach to software.

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.},

We use an Economic approach to propose a theoretical framework for Open Source business analysis and provide a defined sample of real-world developments to support its initial findings. We conclude that the need to develop effective Open Source governance solutions has led to widespread collaboration regarding business and legal challenges by stakeholders in the field, and that this collaboration will increase to improve efficiency as the market matures.},

	abstract = {East Asia nations have made some progress with this technology, and started to introduce OSS for e-government systems during the early part of this century. Many countries granted it a central role in their policies. The reasons for this include adoption of software based on standard specification, liberation from vender lock-in, or opposition to the market control of proprietary software. However, the primary reason is to reduce adoption costs for e-government systems. While this policy work is useful, there is a great deal more that needs to be done. The OSS adoption policy in each nation of East Asia must be accompanied by technological progress in domestic IT service industries or US multinationals will expand at the cost of local businesses. If this continues unchecked it will create a new form of lock-in for East Asian nations. Some Asian nations are trying to promote their domestic IT service industries, putting their OSS adoption policy to practical use, and this workshop will provide case studies of that work. It will also provide a forum for discussing current challenges and opportunities around both policy and practical implementation issues across Asia.},
