科学研究費助成事業データベース(KAKEN)からみる研究活動の状況―研究者からみる論 文産出と職階構造―

要旨

本調査研究は、論文データベース(Web of Science、自然科学系)と科学研究費助成事業(科研費)の成 果データベース(KAKEN)を論文単位で連結し、科研費を得て研究を行った研究者に主体を置いて、科 研費を取り巻く状況(構成・構造)について分析を行った。その結果、系や分野によって、研究者の職階バ ランスは異なり、人文社会系では教授・センター長クラスの割合が相対的に高く、生物系では助教・研究 員・ポスドククラスの割合が相対的に高いことが分かった。研究チーム体制では、ある特定の職階クラスの 研究者のみで構成されている研究課題の割合が、時系列で増加していることが明らかとなった。また、研 究者の他分科との関与度合いは分科により異なり、特定の知識に特化している研究者が多い分科や、他 の分科にも関与しやすい分科があることが分かった。さらに、1 件の論文に関与している研究課題数や分 科数は時系列で増加していることが分かり、近年では、論文と科研費の研究課題は 1 対 1 の対応関係で はなく、複数の研究課題により論文が構成されるようになってきていることが示唆された。

ABSTRACT

This Research Material reports the results of the analysis of the situation surrounding the Grants-in-Aid

for Scientific Research (KAKEN) focusing on researchers who had research grant. This analysis uses

linkage data of Web of Science and database of KAKEN. It was found that balance of researcher’s class of

position differs among research categories and areas. The rate of class of professor is relatively high in the

Humanities and Social Sciences fields, and that is relatively low in the Life sciences fields. The proportion

of the research project which made up of only a particular class of position is increasing. Moreover, the

degree of involvement with other research discipline by researchers is different depending on the research

discipline. It revealed that some research areas composed of researchers specializing in a specific

knowledge, but others are easily involved in other areas. In addition, the number of research projects and

research discipline involved in one paper is increasing. This result suggests that a paper and KAKEN are

not a one to one correspondence in recent day, a paper is becoming to be composed of multiple research

projects.
