摘要
目的:探讨在控制混杂因素影响的条件下,基金资助对中文艾滋病相关论文被引次数的影响。方法:采用倾向指数匹配法控制基金论文与非基金论文的论文发表时间、作者h指数、期刊影响因子等因素对于学术期刊论文单篇累积被引次数的影响。用配对t检验对匹配后基金论文与非基金论文的被引次数进行比较。结果:匹配之前两组间不均衡的混杂因素在匹配之后都达到了均衡。匹配之后基金组与非基金组论文被引次数的差别无统计学意义(P>0.05)。结论:基金资助对中文艾滋病相关论文被引次数的影响无统计学意义,在一定程度上体现出基金资助不能明显提高中文艾滋病相关论文的学术质量与学术影响力。
Objective To study the effect of fund support on cited times of Chinese papers on AIDS by controlling the influence of confounding factors. Methods The effect of publication time of fund-supported papers and non fund-supported papers,h-index of authors,IF of journals on accumulated cited times of each academic paper was controlled by propensity score matching. The cited times of matched fund-supported papers and non fund-supported papers were compared by paired t test.Results The balance of confounding factors which were unbalanced before matching was achieved between fund-supported papers and non fund-supported papers after matching. No significant difference was found between fund-supported papers and non fund-supported papers after matching. Conclusion Fund support does not affect the cited times of Chinese papers on AIDS,which shows that fund support can not noticeably improve the academic level and impact of Chinese papers on AIDS.
