摘要
为改进引文分析方法在探测学科期刊群落结构中的应用,以我国经济学期刊为例,运用社会网络分析法中的相关理论与方法,测度经济学期刊互引网络的结构层次。包括利用中心性分析判断该网络存在单一核心,利用核心-边缘模型将期刊互引网络分成从＂核心＂到＂边缘＂的5个区域。最后将核心度排名结果与CSSCI来源期刊排名相比较,分析了核心度作为期刊评价指标的适用性和优势。认为利用核心-边缘模型可以得出针对任何一个学科门类的期刊核心-边缘分布,并将期刊分层可视化;有助于弥补基于个体属性得出的各种统计指标的不足;可对期刊群进行多层分区,打破＂核心＂与＂非核心＂的二元划分方式。
To improve the citation analysis method as applied for detecting group structure of subject journals,the paper measures the structure of Chinese Economics journals＇ mutual citation network,utilizing the related theories and methods in Social Network Analysis.Firstly,centrality analysis proves that there is only one core in the network.Secondly,making use of core-periphery model,journals＇ citation network is divided into 5 regions from＂core＂to＂periphery＂gradually.Finally,by contrasting the coreness＇ order with the rank of CSSCI source journals,the paper clarifies what the applicable condition and the advantages if the coreness served as an evaluation index.The benefits include acquiring journals＇ core-periphery disputation and its map aimed at whichever subject;making up for the statistic index based on individual attribute;breaking the binary mode of＂core journal＂or＂non-core journal＂and permitting polynary division.
