JIF及其分区对不同国家学者投稿行为的影响研究——基于NPG的月度已录用论文投稿数据

Influence of JIF and Journal Tier on Submission Behaviors in Different Countries——Based on Monthly Accepted Papers of NPG Journals

【目的】期刊影响因子(JIF)及其分区信息是学者进行论文投稿时参考的重要依据,本文拟定量测度JIF和分区信息对不同国家学者的投稿行为的影响。【方法】以自然出版集团(NPG)所出版期刊的《期刊引证报告》(Journal Citation Reports,JCR)及其月度已录用投稿论文数据为例,利用面板负二项回归等统计分析方法,对照两种期刊分区信息:JCR期刊分区和中国科学院文献情报中心期刊分区表(简称“中科院期刊分区表”),探究不同国家的学者对JIF及其分区信息变化的投稿行为差异。【结果】JIF对美国、德国、日本等国学者的已录用投稿论文数存在不同程度的负向影响,JIF提高,其已录用投稿论文数反而减少。而JCR期刊分区对各国学者的已录用投稿论文数均有正向影响,JCR期刊分区上升,其已录用投稿论文数相对增加。中科院期刊分区对中国学者的已录用投稿论文数有正向影响。排除国际合作的影响后,其影响依然表现为正向,相比于JCR期刊分区的影响(3.7%),中科院期刊分区对中国学者投稿行为的影响更大(27.2%)。【局限】利用已录用论文的投稿数据代替期刊实际的收稿数据可能会存在一些偏误。【结论】学者的投稿行为受其所属国家、合作特征及不同期刊分区的影响。本文研究结论丰富了对学者投稿行为影响因素的理解,有助于揭示不同国家学者的投稿行为特征和规律。

[Objective]This paper mesasures the influence of Journal Impact Factor(JIF)and journal tier for scholars’manuscript submission behaviors in different regions.[Methods]First,we collected a journal’s monthly aceptance record and its JIF from Nature Publishing Group(NPG).Then,we examined the submission behaviors with panel negative binomial regression against two journal ranking systems(JCR Quartiles and CAS journal ranking).[Results]JIF has a negative effect on the number of papers submitted by scholars from the United States,Germany,and Japan,i.e.,the number of these papers decreases while the JIF increases.In contrast,the journal’s ranking in JCR had a positive effect on the number of accepted papers from all countries.The CAS journal ranking has a positive effect on the number of accepted submissions from China.After excluding the influence of international collaboration,there are still positive effects.The impact of the CAS journal ranking(27.2%)is much more significant than that of JCR journal partition table(3.7%).[Limitations]We can only access the authors’data of accepted/published papers from WoS journals of NPG rather than the completed submission records.[Conclusions]The submission behaviors of scholars are influenced by their country of residence,independent research,and different journal ranking systems.The findings of this paper will enrich the study of factors influencing scholars’submission behaviors across countries.
