“问题—方法”关联视角下领域知识创新网络演化机制研究——以信息资源管理学科群为例

Research on the Evolution Mechanism of Domain Knowledge Innovation Network from the Perspective of“Issue-Method”Correlation:Taking the Discipline Group of Information Resources Management as an Example

[目的/意义]从“问题—方法”关联视角,探究组合创新模式下的领域知识创新网络的演化机制,试图揭示科学知识创新的潜在影响因素,以便辅助科技政策制定,及时开辟创新发展新赛道。[方法/过程]首先选取信息资源管理学科群,识别领域“问题”与“方法”知识单元,然后以“问题—方法”关联为组合单元,构建领域知识创新网络,最后运用以关系为中心的统计建模方法—指数随机图模型对关系形成及关系模式进行建模,分析网络节点属性特征、网络结构特征等多种内生性和外生性因素对领域知识创新网络形成与演化的影响。[结果/结论]研究发现,期刊分散广度较大的“问题”与“方法”类知识单元形成连边的可能性相对较大,学科领域内部的“问题”与“方法”间形成连边的倾向相对较大,刊载在影响力相对较低的期刊上的“问题”与“方法”相对较易形成连边,下载量较高或被引频次相对较低的“问题”与“方法”知识单元之间形成连边可能性较大。

[Purpose/Significance]From the correlation of“issue-method”,this study explores the evolution mechanism of domain knowledge innovation networks under the combined innovation mode,reveals the potential influencing factors of scientific knowledge innovation,in order to assist in science and technology policy formulation and timely open up new way of innovation and development.[Method/Process]This paper focused on the discipline group of information resource management,identified the knowledge units of“issues”and“methods”in it,and then constructed a domain knowledge innovation network using“Issues-Method”association as a combination unit.Finally,it constructed the model on the relationship formation and relationship patterns with the relationship centered statistical modeling method,Exponential Random Graph Model,and analyzed the impact of various endogenous and exogenous factors,such as network node attribute and network structure,on the formation and evolution of domain knowledge innovation networks.[Result/Conclusion]It shows that the possibility of“issue-method”correlation is relatively large in journals with large dispersion breadth.Within disciplines,the tendency of“issue-method”correlation is relatively high.“Issues-method”correlation in journals with relatively low impact are more easily to form edges.In literatures with high downloads or relatively low citation frequency,it is more likely that the edge between“issues”and“method”knowledge units is formed.
