学科交叉与知识扩散相关性研究--以基因工程领域为例

Research on Relationship Between Interdisciplinarity and Knowledge Diffusion--Taking the Field of Genetic Engineering as an Example

[目的/意义]从学科交叉综合指标和多样性、均衡性及差异性3个单一维度指标角度探究论文学科交叉和知识扩散的关系,为论文引用学科布局提供参考,促进论文的知识扩散程度,提升论文的影响力。[方法/过程]本研究选取Web of Science数据库2000—2018年基因工程领域论文,采用Tobit回归模型从多个维度探究学科交叉指标与知识扩散指标关系。[结果/结论]研究表明:学科交叉各指标与知识扩散各指标基本呈现U型或倒U型关系;学科交叉对知识扩散的影响存在最优值;基因工程领域论文需要适当调整引文学科种类、差异和均衡程度,以期提高知识扩散的程度。

[Purpose/Significance]From the perspective of comprehensive cross-disciplinary indicators and three sin⁃gle-dimensional indicators of variety,balance and difference,we will explore the relationship between the interdisciplinary and knowledge diffusion of papers,providing a reference for the discipline layout cited in the paper,promoting the degree of knowledge diffusion of papers,and enhancing the influence of papers.[Method/Process]Papers in the field of genetic engineering from 2000 to 2018 in Web of Science database were selected to explore the relationship between interdisciplinary indicators and knowledge diffusion indicators from multiple dimensions by using Tobit regression model.[Result/Conclu⁃sion]The indicators of interdisciplinary and knowledge diffusion basically show a U-shaped or inverted U-shaped relation⁃ship.There is an optimal value for the influence of interdisciplinary interaction on knowledge diffusion.The subject types,disparity degree and balance degree of references need to be adjusted properly so as to improve the degree of knowledge dif⁃fusion in the field of genetic engineering.
