The Life Course of Former Coal Mine Workers : Construction of Work Career Data Base and Sociological analysis

本研究的目的是通过日本东北部的一个例子，详细描述日本煤炭采矿业的发展和消亡的历史经济和社会学意义，日本煤炭采矿业在19世纪到20世纪中期通过提供初级能源来维持重资本主义的基础。我们还将比较历史记录和数据存储在一个可检索的系统中。上述目标是通过以下五个步骤实现的。(1)构建了Joban煤矿公司89%曾受雇工人职业生涯微观数据的大型数据库。(2)对个体矿工从初次就业到终止就业的各种职业生涯进行纵向分析。(3)分析煤矿职工在职与关停后工作的联系及非自愿职业中断的影响。(4)数据库的构建和分离过程的分析，对曾在Joban煤矿公司工作过的前矿工的更多工作。(5)各类微数据数字化后的大规模微数据的公共利用。对50年代末至60年代初的所有工人就业记录（约8万件）进行了数字化，并建立了整个6459名煤矿工人详细职业生涯的大型数据库。另一方面，1971年煤矿关闭时有4209名工人。对因煤矿关闭而失去事业的3847人（89%）进行了追踪调查（调查完成者1427人（34%）、无法调查者879人（21%）、确认死亡者1441人（34%））。将这些人在矿井工作期间的职业生涯数据与矿井关闭后的职业生涯数据相连接，构建了他们一生的职业生涯数据库。利用上述全生命周期的职业数据，对非自愿中断职业、中断就业后的职业和退休后的生活的影响进行分析，并将结果发表。本研究构建的部分大型微数据库档案在我们的网站上向公众开放。少

The objectives of this study is to describe in detail the historical economic and sociological significance of the development and demise of the coal mining industry in Japan which sustained the basis of heavy capitalism by supplying primary energy during the 19^<th> to the mid-20^<th> Century through an example in Northeast Japan. Also we stored comparative historical records and data in a retrievable system. The above objective was accomplished through the following five steps.(1) Construction of a large data base of micro-data regarding the careers of 89% of the workers who were once employed by the Joban Coal Mine Co.(2) Longitudinal analysis of various careers of individual miners from the initial employment to the termination of employment.(3) Analyses of the connection between the careers at the mine and those of the jobs after the closure of the mine and of the effect of involuntary career interruption.(4) Construction of data base and analysis of the process of separation from … More work for the former miners who had once worked at the Joban Coal Mine Co..(5) Public usage of the large-scale micro data after digitizing the various micro data.All records of workers' employment during the late 1950s to early 60s (about 80,000 events) were digitized and a large-scale data base of the detailed careers of the entire 6,459 coal-mine workers was constructed. On the other hand, there were 4,209 workers at the mine closure in 1971. Eighty-nine percent of them, namely 3,747 people, whose careers were severed by the closure of the mine were traced and surveyed (survey completed 1,427 people (34%), survey impossible 879 people (21%), death confirmed 1,441 people (34%)). The career data of these people during employment at the mine and those after the closure of the mine were connected and a career data base for their entire lives was constructed.The effects of involuntary interruption of careers, careers after disruption of employment, and their lives during retirement were analyzed using the above career data for the entire lives, and the results were published. A part of the large-scale micro-data base archive constructed by this study is open to the public on our website. Less
