摘要：

【目的】基于内部知识结构探索学术期刊跨学科性与其影响力的关系,为期刊发展及学者提供参考。【方法】以CSSCI图情档期刊为例,计算其知识多样性、知识均匀性、跨学科程度及影响力指标;进行时间序列分析,研究发展趋势;采用回归分析探索期刊跨学科性及影响力之间的关系。【结果】期刊知识多样性逐年升高,表明各期刊研究主题多元化程度逐渐提升;知识均匀性表现出较大差异,76%的期刊的知识均匀性呈下降趋势,表明大部分期刊形成优势主题并积极吸纳更多主题;跨学科程度逐年升高,期刊知识整合及创新性不断增强。【结论】期刊的知识多样性和跨学科程度显著正向影响期刊影响力;知识均匀性与跨学科程度存在相关性,但具体表现需要进一步探索。期刊应注重学科知识多元化发展,提高优势学科内容与其他学科知识的整合程度,以促进期刊的健康发展。

Abstract:

[Purposes] This paper aims to explore the relationship between interdisciplinarity and impact based on the internal knowledge structure of academic journals and to provide references for journal development and scholars. [Methods] Taking the journals of library and information science indexed by CSSCI as the data source, we calculated the knowledge diversity, knowledge balance, interdisciplinary degree, and impact index and then carried out the time series analysis to study the development trend. The regression analysis was performed to explore the relationship between interdisciplinarity and impact. [Findings] The knowledge diversity increases year by year, indicating that the research topics of each journal become increasingly diverse. Knowledge balance shows large variations, showing a downward trend in 76% journals, which indicates that most journals have formed dominant topics and actively absorbed additional topics. The interdisciplinary degree increases year by year, and the integration and innovation of knowledge have been continuously enhanced. [Conclusions] The knowledge diversity and interdisciplinary degree of journals positively influence journal impact. There is a correlation between knowledge balance and interdisciplinary degree, which remains to be explored. It is important for the healthy development of the journals to focus on the diversification of subject knowledge and the integration of the content of dominant subjects with the knowledge of other subjects.
