Abstract：
UNASSIGNED: Prompted by the clinical concern that limited healthcare resources allocation affects physicians\' research productivity, this study examines the association between bibliometric indices of ophthalmologic research and national economic indicators in Organisation for Economic Co-operation and Development (OECD) countries.
UNASSIGNED: The Scimago Journal and Country rank source was searched for research productivity data in ophthalmology among OECD countries between 1996 and 2019. Bibliometric indices included: documents number, number and percent of citable documents, citations number, citations per document, and H-index. The updated economic indicators of each country (gross domestic product [GDP] per capita, health spending as percent of GDP (health expenditure), gross domestic expenditure on research, and development as percent of GDP [GERD]) were collected from the World Bank and the OECD websites. Correlation between economic and bibliometric metrics and multivariate linear regression analyses were performed.
UNASSIGNED: Among 267,444 documents analyzed, correlation analysis found a strong correlation between health expenditure and H index (r = 0.711, p < 0.001); a moderate correlation between health expenditure and documents number (r = 0.589, p < 0.001), number of citable document (r = 0.593, p < 0.001) and citations number (r = 0.673, p < 0.001); and a moderate correlation between GERD and H index (r = 0.564, p < 0.001). Multivariate regression analysis controlling for economic factors, population and language showed the independent association of these parameters with bibliometric indices.
UNASSIGNED: This study demonstrates a positive correlation between bibliometric indicators of ophthalmology research and economic factors, particularly health expenditure, among the OECD countries. Our results suggest an advantage of domestic investment in health to expand academic productivity in the field of ophthalmology.

摘要：
■由于临床担心有限的医疗保健资源分配会影响医生的研究生产率，本研究考察了经济合作与发展组织(OECD)国家眼科研究的文献计量指标与国家经济指标之间的关系.
■在1996年至2019年间，搜索了《ScimagoJournalandCountry》排名来源，以获取经合组织国家在眼科方面的研究生产率数据。文献计量指标包括：文献编号，可引用文档的数量和百分比，引用号,每个文档的引用次数，和H指数。每个国家的最新经济指标(人均国内生产总值[国内生产总值]，卫生支出占GDP的百分比(卫生支出)，用于研究的国内总支出，和发展占GDP[GERD]的百分比）是从世界银行和经合组织网站上收集的。进行了经济和文献计量指标与多元线性回归分析之间的相关性。
■在分析的267,444个文档中，相关分析发现卫生支出与H指数之间有很强的相关性（r=0.711，p<0.001）；卫生支出与文献数量之间有中等的相关性（r=0.589，p<0.001），引用文献数(r=0.593,p<0.001)和引用文献数(r=0.673,p<0.001);GERD与H指数呈中等相关性(r=0.564,p<0.001)。控制经济因素的多元回归分析，人口和语言显示了这些参数与文献计量指数的独立关联。
■这项研究表明，眼科研究的文献计量指标与经济因素之间存在正相关关系，特别是卫生支出，在OECD国家中。我们的结果表明，国内卫生投资有利于扩大眼科领域的学术生产力。
