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19 ~ 20世纪中期，作为一次能源供应基础的日本煤炭开采业的发展和消亡的历史、经济和社会学意义<th><th>。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)建立了一个大型的微观数据库，其中包括89%曾经受雇于常板煤矿公司的工人的职业生涯。(2)对个体矿工从最初就业到终止就业的各种职业进行纵向分析。(3)分析矿井职业与矿井关闭后工作之间的联系以及非自愿职业中断的影响。(4)数据库的构建与分离过程分析 关于我们 为曾在常班煤矿公司工作的前矿工工作。(5)对各种微观数据进行数字化后的大规模微观数据的公开使用。将50年代末至60年代初的所有工人就业记录（约8万次）数字化，并建立了一个包含整个6，459名煤矿工人详细职业生涯的大规模数据库。另一方面，1971年矿井关闭时有4,209名工人。对其中89%，即3 747名因矿井关闭而中断职业生涯的人进行了追踪和调查（完成调查1 427人（34%），无法调查879人（21%），确认死亡1 441人（34%））。将这些人在矿山工作期间和矿山关闭后的职业生涯数据连接起来，构建了他们一生的职业生涯数据库，利用上述一生的职业生涯数据，分析了职业生涯的非自愿中断、中断后的职业生涯以及退休期间的生活所产生的影响，并公布了结果。本研究建立的大规模微观数据库档案的一部分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
