Research on unpaid-works inside Japanese households from the perspective of world-system.

2004年，我访问了瑞典统计局和芬兰统计局，我听说了比较欧共体国家的时间使用调查的调查方法。我收集了欧盟统计局关于时间使用调查的资料，并将《欧洲时间使用调查协调指南，Eurostat， 2000》翻译成日文。论文发表在《长野大学学报》2005年第27卷第3期。我用同样的方法，同样的方法，同样的代码，调查了长野县的500对夫妇的时间使用情况，并分析了调查数据。我将其与欧洲的研究结果进行了比较。我在2005年第78届“日本经济学会”年会上发表了这篇文章。我从世界体系的角度收集了关于家庭研究的文件，并对它们进行了调查。我试图建立一个新的理论框架，从世界体系的角度来把握和分析家庭内部的各种无偿劳动。

In 2004, I visited Statistics Sweden and Statistics Finland, I heard about the investigation method of the time use survey for compareing EC countries. I collected documents about time use surveys of Eurostat Statistics Bureau, and I translated " The Guidelines on harmonized European Time use surveys, Eurostat, 2000" into Japanese. I published it in the Bulletin of Nagano University Vol.27,No.3,2005. With the same method and the same method and the same code, I investigated time use of the 500 couples in Nagano prefecture and I analyzed the survey data. I compared it to the European findings. I presented it at the 78th annual conference of "nihon shakai gakkai",2005. I collected documents about households studies from the point of view of the world-system, and I surveyed them. I am trying to build a new theoretical framework which can grasp and analyze for various kind of unpaid-works within households from the world-system perspective.
