ABSTRACT This study analyzed the factors required for a researcher to become a professor in the humanities and sociology, science and engineering, medicine and biology, and general studies fields. The study focuses on research productivity and analyzes the impact of hiatuses in research production on promotion in universities as well as the time at which such hiatuses have the least impact on promotions. I divided the factors required for promotion into three categories: academic performance (the number of published articles, books, and competitive grants and funding sources acquired), social elements (gender), and elements related to the duration of periods with no research output and their timing. The results show that the probability of promotion to professorship increases as the number of papers in Scopus, the number of books published, and the amount of acquired competitive funds increase. As expected, longer declines in research productivity reduce the probability of promotion. However, it is not always necessary for researchers to publish continuously throughout their careers; the results show that a decline in research productivity other than during the first five years and the period from 20 to 30 years after the start of the research career has no influence on academic promotions.

学术研究人员什么时候可以休息？1980-2016年日本学术界研究人员研究生产力和发展的事件历史分析

摘要本研究分析了研究人员成为人文与社会学，科学与工程，医学与生物学以及常识研究领域教授所需的因素。该研究侧重于研究生产力，并分析了研究活动中的休假对大学晋升的影响以及这种休止对晋升的影响最小的时间。我将晋升所需的因素分为三类：学习成绩（已发表的文章，书籍的数量以及获得的竞争性赠款和资金来源），社会因素（性别）以及与没有研究成果的时期有关的因素。他们的时机。结果表明，晋升为教授职位的可能性随Scopus中的论文数量，已出版的书籍数量，获得的竞争性资金的数量增加。不出所料，研究生产力的长期下降会降低晋升的可能性。但是，研究人员不一定在整个职业生涯中都持续发表论文。结果表明，除了在开始的头五年以及研究生涯开始后的20至30年期间之外，研究生产率的下降对学术晋升没有影响。
