OBJECTIVES
The objective of this study was to identify the top 50 countries in the world in clinical neurology research and to use their data to assess the impact of a number of country-specific characteristics on scientific productivity in clinical neurology.
METHODS
The SCImago Journal & Country Rank (SCR) web site was used to identify the top 50 countries in the world based on their total documents in clinical neurology. Using their data 5 country-specific characteristics and 6 productivity indicators (total documents, total cites, -index, citable documents, self-cites and citations per document) were correlated and examined statistically.
RESULTS
The number of universities in the world top 500 and the number of clinical neurology journals enlisted in SCR correlated significantly with each of the 6 indicators. The gross domestic product (GDP) per capita and the percentage of GDP spent on research and development (R & D) correlated significantly with 3 and 4 out of the 6 indicators respectively. The population size did not correlate significantly with any of the 6 indicators.
CONCLUSIONS
The number of universities in the world top 500 and the number of clinical neurology journals enlisted in SCR appear to have a strong impact on scientific productivity. GDP per capita and spending on R & D appear to have a moderate impact on productivity that is influenced by the indicator used. Furthermore, population size appears to have no significant impact on productivity in clinical neurology research.
目的
本研究的目的是确定世界上临床神经学研究排名前50的国家，并利用其数据评估一些特定国家特征对临床神经学科研生产力的影响。
方法
使用Scimago期刊与国家排名（SCR）网站，根据临床神经学领域的文献总量确定世界上排名前50的国家。利用这些国家的数据，将5个特定国家特征和6个生产力指标（文献总量、总被引次数、h指数、可引用文献、自引次数和每篇文献的被引次数）进行相关性分析并进行统计学检验。
结果
世界排名前500的大学数量以及SCR收录的临床神经学期刊数量与6个指标中的每一个均显著相关。人均国内生产总值（GDP）和研发（R&D）支出占GDP的百分比分别与6个指标中的3个和4个显著相关。人口规模与6个指标中的任何一个均无显著相关性。
结论
世界排名前500的大学数量以及SCR收录的临床神经学期刊数量似乎对科研生产力有很大影响。人均GDP和研发支出似乎对生产力有中等程度的影响，这取决于所使用的指标。此外，人口规模似乎对临床神经学研究的生产力没有显著影响。
