A preliminary research for a new survey on the Japanese national character

统计数学研究所研究委员会对日本国民性的研究始于1953年的第一次全国调查。此后，每五年进行一次类似的统计调查，共进行九次调查。最近的第九次全国调查是在1993年10月进行的，通过对这段时间里反复提问的回答的分析，得到了以下事实发现：(1)在过去的40年里，人们对政治问题、日常生活、日本人的感情和思想等的态度发生了很大的变化。相比之下，人们对人际关系的态度在这段时间里变化很小。(2)态度趋势的现代化在20世纪70年代初的S略有逆转或延迟。(3)在70年代的S之后，认为私人生活最重要的人的数量稳步增加。但是，为了弄清最近和未来意见趋势的细节，我们必须开发新的问卷。为此，我们在本研究项目中进行了以下几个方面的研究：(1)使用新的问卷项目对第十次全国调查进行了前测，并对结果进行了分析。(2)对九次日本国民性格调查的数据文件进行了修订。此外，我们还为这些调查的开放式问题制作了一个新的数据文件。

The study of the Japanese national character by the Research Committee of The Institute of Statistical Mathematics originated with the first nationwide survey in 1953. Since then, a similar statistical survey has been conducted every five years, for a total of nine surveys. The latest ninth nationwide survey was carried out in October 1993.From the analysis of responses to questions repeatedly asked over this period, the following fact findings were obtained.(1) There have been great shifts in attitudes toward political problems, daily life, Japanese feelings and ideas and so on for the past forty years. In contrast, attitudes toward personal relations have changed very little over this period.(2) The modernization in the attitude trend has been slightly reversed or delayd in the early 1970's.(3) After the 1970's, there has been a steady increase in the number of people who think their private life most important.However, in order to cralify details of recent and future opinion trends, we must develop new questionnaires. For this purpose, we investigated the following matters in this research project.(1) We carried out a pretest for the tenth nationwide survey using new questionnaire items, and analyzed the results.(2) We revised the data file of the nine surveys of the Japanese national character. Furthermore, we made a new data file for open-ended questions of those surveys.
