This study looks at the state of collaboration in scientific research between universities and industries in Japan by measuring the level of coauthorship of academic publications. The analysis is based on data retrieved from the databases of the National Citation Report for Japan, which was produced by Thomson Scientific (ISI) and included papers published from 1981 to 2003, and the Citation Database for Japanese Papers, which was produced by the National Institute of Informatics, Japan, and included papers published from 1995 to 2004. It is revealed that there is a large 'perception gap' between industries and universities concerning their collaborations. The situation, trends and characteristics of industry-university collaborations are investigated and discussed from international and national perspectives. The disciplinary and regional differences in such collaborations are also discussed. [ABSTRACT FROM AUTHOR]

The Great Kantō Earthquake in 1923 did enormous damage to industries in Tokyo Prefecture. Around 40% of the buildings in Tokyo Prefecture were completely burnt or destroyed. In this paper, we investigate whether this temporary shock had a persistent impact on the spatial distribution of industries in Tokyo, using ward- and county-level panel data for industrial workers. It was found that while the earthquake caused mean shifts in the shares and numbers of workers, these mean shifts disappeared by the early 1930s. On the other hand, the earthquake caused shifts in the trends in the share and number of workers. The combined effects of these mean shifts and trend shifts were persistent for both the shares and the numbers of workers. The earthquake caused especially serious damage to the old industrial clusters in the southeast of Tokyo, and provided an opportunity for newly developing industrial clusters in non-damaged areas to take over the market. Further, the people and the local governments in non-damaged areas made an effort to take advantage of this opportunity to attract factories. Arguably, these forces made the impact of the earthquake on the spatial distribution of industry persistent. [ABSTRACT FROM AUTHOR]
