In recent years the number of academic papers being published on research and development has
been increasing more slowly in Japan than in other leading nations. One of the reasons for this
may be the low ratio of internationally-collaborated articles in Japan, which tend to have more
citations than those written by domestic groups or individuals. However, up until now two major
themes have still not been investigated: factors related to international co-authorship and the
international mobility of researchers, and the reasons behind the higher citation rates of
internationally-collaborated articles. Therefore, this study examines those two themes by
empirical analysis using two types of datasets created through use of the Web of Knowledge
provided by Thomson Reuters. One of the results gained from analysis on papers published in the
past 20 years in Nature and Science using a count data regression model indicated several factors
that have a positive relationship with the production of academic papers: investment on R&D and
the number of researchers, the number of international students, and European Union membership.
The mobility of international researchers had a positive relationship with the number of
researchers at the transfer locations. Analysis using a database of papers in the field of chemistry
showed positive correlations between research performance (number of papers and their times
cited) and the degree of international collaboration. These tendencies appear to be common in
Japan, as well as in the United States, the United Kingdom, and China.

Building a mechanism of science and technology innovation activities in a region is required, which is to make use of the strengths and characteristics of regions and can be deployed autonomously. Therefore, universities are expected to work with such local companies as a member of the local community, and to contribute to the construction of a regional innovation system. Then, in order to clarify the achievements and issues of the industry academic collaboration in region, the National Institute of Science and Technology Policy(NISTEP) conducted research on industry-academia collaboration to target the manufacturing industry in Kagoshima Prefecture as a case study in fiscal year 2011 (Sotohebo-Nakatake 2012). In 2012 we conducted a questionnaire 2 survey by mail to target the 2900manufacturing companies to put headquarters, factories, and offices in Chukyo area which includes Aichi Prefecture, Gifu Prefecture and Mie Prefecture, and the survey was obtained valid responses of 694companies (23.9% response rate).Chukyo area is the leading industry agglomerations of manufacturing industry of Japan, in which companies has positively conducted development of new products and technologies. And these companies are willing to do industry-academia collaboration mainly in Aichi Prefecture. There are not only varieties of public universities but also a lot of private universities in Chukyo area, thus local resources are also plentiful. In order to activate more industry-academia collaboration in the future, the universities and national technology collages should establish their own specialties. Moreover, instead of restricted their industry-academia collaboration activities within the prefectural area, it should be necessary to mutually lending resources each other in Chukyo area.

In order to provide evidence for science, technology and innovation policy, this study aims to make a
method for quantitative analysis of economic and social impacts caused by government investment in
science and technology. This paper discusses a method to estimate economic and environmental impacts of
new industries in the future created by science and technology innovation. We have taken up renewable
energy that is expected as a new growing industry in the future, then estimated direct and indirect effects of
output, employment, energy consumption and CO2 emission in terms of the construction of renewable
energy power plants by input-output analysis. The estimated results show that the indirect effect of
employment is smaller than the direct effect. Meanwhile, the indirect effects of energy consumption and
CO2 emission are larger than the direct effects. Analysis on every industrial sector identified influential
sectors for direct and indirect effects, which suggest the research and development for reducing costs,
energy consumption and CO2 emission in power plant construction. Furthermore, comprehensive analysis
on economic and environmental impacts suggests ways of research and development for power plant
construction to reduce the costs, energy consumption and CO2 emission with attention of domestic
employment.
