肿瘤学meta分析论文被引频次与期刊开放获取相关性分析

Correlation analysis between citation frequency of oncology meta-analysis papers and journal open access

【目的】分析肿瘤学meta分析论文的现状,并探讨期刊类型与肿瘤学meta分析论文被引用情况的相关性,为学者选择期刊宣传科研成果提供参考。【方法】选取2011—2016年SCI收录的肿瘤学meta分析论文作为研究对象,提取论文的引用频次、发表国别、期刊影响因子、期刊类型等信息。【结果】目前我国发表的肿瘤学meta分析论文数量虽位居全球第一,但篇均被引频次最低。2011—2016年,开放性meta分析论文的数量呈上升趋势。肿瘤学meta分析论文的被引频次与期刊类型具有低相关性。肿瘤学meta分析的非开放性期刊论文的篇均被引频次高于开放获取期刊论文,高被引论文的来源期刊平均影响因子比低被引论文高。【结论】肿瘤学meta分析的开放获取期刊不存在引用优势,论文质量仍然是meta分析论文被引频次的主要因素。

[Purposes] This study aims to analyze the status of oncology meta-analysis papers,and to explore the correlation betw een journal types and citation frequency of oncology meta-analysis papers,w hich can provide reference for scholars to advertise their researches. [Methods]The oncology meta-analysis papers published from 2011 to 2016 w ere took as research objects to extract the informations of citation frequency,authors＇ countries,impact factors,journal types. [Findings]The number of oncology metaanalysis papers published by Chinese authors ranks first in the w orld,but the average citation frequency per paper is the low est among the researched countries. In the period of 2011—2016,the number of open access（ OA） meta-analysis papers is on the rise.The citation frequency of oncology meta-analysis papers has low correlation w ith journal types. The average impact factor and citation frequency of non-OA journals of meta-analysis in oncology field are higher than those of OA journals. The average impact factor of high citation frequency papers is higher than that of low citation frequency papers. [Conclusions] There is no citation advantage in OA journals of oncology meta-analysis papers,and the paper quality is still the main factor of meta-analysis papers.
