Despite the significant number of research institutions and rich scientific heritage, published research from Central Asia (Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan) is traditionally underrepresented in international scientific literature. The goal of this paper was to analyze publication patterns in Central Asian countries, and to explore the factors that contributed to the publication productivity in Kazakhstan.
Publication productivity was evaluated using data generated by the SCImago Journal & Country Rank over the period of 1996-2014 for all of the 15 former Soviet Union Republics for all subject categories. Country specific data, including total population, gross domestic product (GDP) per capita, research and development (R&D) expenditure (% of GDP), number of reserchers (per million people), was abstracted from World Bank data. ANOVA and ANCOVA analyses compared the mean number of publications among Central Asian countries. Separate analyses was done for publication patterns in the health sciences. Multiple comparisons were performed using Tukey method.
The analysis of publication productivity showed significant discrepancies in the number of published documents among the Central Asian countries. Kazakhstan demonstrated a significant increase in the number of published documents in the period of 1996-2014, mainly in the areas of natural and multidisciplinary sciences. Our analyses also showed that the number of publications are siginicantly associated with GDP and population size.
We identified large gaps in publication productivity among the Central Asian countries. The association between publication rate with GDP and population size indicates there is a need to adjust for these factors when planning research policy.
尽管中亚地区（哈萨克斯坦、乌兹别克斯坦、吉尔吉斯斯坦、塔吉克斯坦和土库曼斯坦）有大量研究机构且拥有丰富的科学遗产，但该地区发表的研究成果在国际科学文献中传统上所占比例较低。本文的目的是分析中亚国家的出版模式，并探讨促成哈萨克斯坦出版生产力的因素。
利用Scimago期刊与国家排名在1996 - 2014年期间生成的数据，对所有15个前苏联共和国所有学科类别的出版生产力进行评估。从世界银行数据中提取各国特定数据，包括总人口、人均国内生产总值（GDP）、研发支出（占GDP的百分比）、研究人员数量（每百万人口）。方差分析（ANOVA）和协方差分析（ANCOVA）比较了中亚国家之间的平均出版物数量。对健康科学领域的出版模式进行了单独分析。使用Tukey方法进行多重比较。
出版生产力分析显示，中亚国家之间发表文献的数量存在显著差异。哈萨克斯坦在1996 - 2014年期间发表文献的数量显著增加，主要集中在自然科学和多学科领域。我们的分析还表明，出版物数量与GDP和人口规模显著相关。
我们发现中亚国家在出版生产力方面存在巨大差距。出版率与GDP和人口规模之间的关联表明，在制定研究政策时需要对这些因素进行调整。
