近五年皮肤病学与性病学领域作者中文合著分析

An analysis of the co-author networks in recent five-year Chinese papers in dermatology and venereology field

目的运用社会网络分析方法探讨近5年我国皮肤病学与性病学领域作者合著现象。方法以该领域9种影响因子较高的期刊为样本，利用UCINET软件从网络密度、中心性和凝聚子群3个方面进行分析。结果作者合著网络密度为0．3313，点度中心性值最高的节点是孙建方，中间中心性值最高的节点是黄长征，122位核心作者构成10个2一丛。结论该领域的论文合著率较高，但网络密度值不高，即使核心作者之间的联系也不紧密，网络中存在着孤立节点。相对于非活跃用户而言，活跃用户间的差异更大，网络总体一致性较低，整个网络中信息交流对桥梁作者的依赖性也不强，同时，目前该领域尚未形成明显的小团体现象。

Objective Purpose to study the domestic conditions of co-authorship in the field of dermatology and venereology in recent five years. Methods Taking 9 higher impact factor periodicals of the field as samples and using UCINET software to conduct research from following three perspectives, density, degree centrality, betweenness centrality and subgroup analysis. Results The density of co-authoring network is 0. 3313. SUN Jian-fang possesses the highest value of degree centrality, and HUANG Chang-zheng＇s value of betweenness centrality is the highest. Ten 2-plexes are found in 122 core authors. Conclusions The study found that papers in this field have a high co-authored rate. But the lower network density and isolated nodes indicate that the connection between core authors is loose. There are more notable differences between active authors than inactive ones. The consistency of overall network is poor and other authors＇ dependence of central authors is weak across the entire network. Meanwhile, authors of this field have not yet formed a subgroup phenomenon.
