摘要：

【目的】 研究2011—2021年中美化学类期刊开放获取(Open Access, OA)论文数量与影响力的差异,提出我国化学类期刊现阶段发展的建议,并为其OA转型提供参考。【方法】 基于Web of Science数据库,统计国际期刊、中国期刊、美国期刊上中国作者与美国作者论文总量、OA论文数量与引证指标等数据,并采用文献计量学方法进行对比分析。【结果】 (1)近11年中国作者论文总量占全球总发文量的年平均值为30.30%,其中OA论文占比为5.64%,而美国作者的论文总量在全球期刊总发文量的占比年平均值为15.39%,其中OA论文占比为5.68%。近5年来中国作者论文总量与OA论文数量均超过美国作者,但美国作者OA论文的引文影响力与高水平论文占比高于中国作者的OA论文。(2)中国化学期刊数量少、平均载文量少,造成中国化学期刊上的论文总量少,近11年在国际化学学科论文总数中平均占比为2.28%,而美国化学期刊数量多、平均载文量多,所以期刊论文总量多,在国际论文总量中占比均值为26.68%。(3)近11年中国与美国论文总量的平均逆差指数为84.91,中国论文流向美国的平均比率为76.3%。中国论文总量国外逆差指数平均为167(最高为2021年的390),OA论文的国外逆差指数平均为97,中国论文总量的外流率平均值为93.0%。而美国不论是化学论文总量还是OA论文数量,总体上都表现为顺差。【结论】 建议采取创办化学学科新OA期刊,鼓励我国科研工作者将优秀成果发表在本土期刊,开通“论文转投”通道,加强现有化学期刊向OA转型等策略,在一定程度上遏制我国化学学科论文的外流,促进化学类期刊的发展。

Abstract:

[Purposes] This paper studies the differences between the number and influence of open access (OA) papers in Chinese and American chemical journals from 2011 to 2021, puts forward some suggestions for the development of Chinese chemical journals, and provides reference for their OA transformation. [Methods] Based on Web of Science database, the total number of papers, the number and citation index of OA papers published by Chinese and American authors in international journals, Chinese journals, and American journals were counted and analyzed by bibliometrics. [Findings] (1) In the past 11 years, the average number of papers of Chinese authors accounted for 30.30% of the total number of papers published in the world, and the average proportion of OA papers was 5.64%, while the average number of papers of American authors accounted for 15.39%, and the average proportion of OA papers of American authors was 5.68%. In particular, the total number of Chinese authors' papers and the number of OA papers exceeded those of American authors in recent 5 years. OA papers of American authors have higher citation impact and proportion of the high-level papers than Chinese OA papers. (2) The number of chemical journals in China and the average volume of papers are small, resulting in a small number of papers in Chinese chemical journals, only accounting for an average of 2.28% in the total number of papers in international chemistry in recent 11 years. However, the number of chemical journals in America and the average volume of papers are large, which accounts for an average of 26.68% in the total number of papers in international chemistry. (3) The average deficit index of total papers in China and America was 84.91, and the average ratio of Chinese papers flowing to America was 76.3%. In recent 11 years, the average foreign deficit index of Chinese papers is 167 (the highest is 390 in 2021), the average foreign deficit index of OA papers is 97, and the average total outflow rate of Chinese papers is 93.0%. America shows a surplus in the total number of chemical papers and OA papers. [Conclusions] Some strategies should be considered to be adopted, such as launching new OA journals about chemical disciplines, encouraging researchers workers to publish outstanding achievements in domestic journals, opening the channel for "paper transfer", strengthening the transformation of the domestic chemical journals into OA journals, in order to curb the outflow of chemical papers in some degree and promote the development of chemical scientific journals in China.
