The study presents the bibliometric analysis of the Spanish scientific output in biomedicine during 1996-2004. This is the last edition of a series of bibliometric studies aimed to characterize the Spanish scientific performance in biomedicine.
The analysis was restricted to citable documents for which simple and composite bibliometric indicators were obtained at different aggregation levels: fields, autonomous regions, institutional sectors and research centres. The documents were selected according to the Journal Citation Reports, and were assigned to affiliation centres following an integer counting scheme after an exhaustive normalization of the affiliation addresses.
Compared to the period 1994-2002, research activity in biomedicine grew as much as Spain: 8.9% in the number of documents; 22.5% citations; 12.5% citation per document average and 27.2% international cooperation. Besides, biomedicine showed the highest citation per document average compared to other major fields. International cooperation in biomedicine (27.2%) reached the European average. The documents published in international cooperation account for the half of citations to documents in biomedicine. The number of documents and citations belonging to the clinic medicine subfield and to the health sector showed the highest growth.
In general, these results reproduce the tendencies described in prior studies. The documents in biomedicine showed a highly asymmetric distribution among institutional sectors, autonomous regions, scientific fields and research centres. The remarkably increase in the output of clinical medicine field and in the health sector could be the consequence of important science policy actions undertaken in these areas in the last years.
本研究呈现了1996 - 2004年西班牙生物医学领域科研产出的文献计量分析。这是一系列旨在描述西班牙生物医学科研表现的文献计量研究的最后一版。
分析仅限于可引用文献，在不同汇总层面（领域、自治区、机构部门和研究中心）获取了简单和复合的文献计量指标。文献根据《期刊引证报告》进行选取，并在对所属地址进行详尽归一化处理后，按照整数计数方案分配至所属中心。
与1994 - 2002年期间相比，西班牙生物医学领域的研究活动增长情况如下：文献数量增长8.9%；被引频次增长22.5%；平均每篇文献被引频次增长12.5%；国际合作增长27.2%。此外，与其他主要领域相比，生物医学领域平均每篇文献的被引频次最高。生物医学领域的国际合作（27.2%）达到了欧洲平均水平。国际合作发表的文献占生物医学领域文献被引频次的一半。临床医学子领域和卫生部门的文献数量及被引频次增长最为显著。
总体而言，这些结果重现了先前研究中描述的趋势。生物医学领域的文献在机构部门、自治区、科学领域和研究中心之间呈现出高度不对称的分布。临床医学领域和卫生部门产出的显著增加可能是过去几年在这些领域采取的重要科学政策行动的结果。
