In this project, we have conducted the research on 1.Current trend and sustainability of IT innovation, 2.IT's impact on industrial organization and structure and 3.Economic implications on IT using industries. The results can be summarized as follows,・It is found that IT innovation has been accelerated since the mid 1990's, while Moore's law on semiconductor lasts for more than 30 years. Downsizing of computer system and proliferation of Internet contribute to this trend of IT innovation.・IT's impact on industrial organization and structure cannot be seen as an industry wide phenomenon. Modularization of production system and unbundling of value chain can be observed in electronics industry, but not for other industries.・It is found that the impact of IT on economic growth is not so difference between Japan and the United States. However, firm level analysis shows that its impact on IT using industry is smaller in Japan as compared to the US. That is, IT's contribution to economic growth in Japan can be explained mainly by productivity growth in IT supplier industries.

在本项目中，我们进行了以下研究：1.信息技术创新的趋势和可持续性；2.信息技术对产业组织和结构的影响；3.对信息技术应用行业的经济影响。研究结果表明，自上世纪90年代中期以来，中国的信息技术创新呈现加速趋势，而S的半导体摩尔定律持续了30多年。计算机系统的小型化和互联网的激增促成了这一IT创新的趋势。·IT对产业组织和结构的影响不能被视为全行业的现象。电子行业出现了生产系统模块化和价值链解绑的现象，而其他行业则没有。·研究发现，IT对经济增长的影响在日本和美国没有那么大的差异。然而，企业层面的分析表明，与美国相比，它对日本IT使用行业的影响要小得多。也就是说，IT对日本经济增长的贡献主要可以通过IT供应商行业的生产率增长来解释。
