摘　　要：目的运用社会网络分析中隶属网络矩阵分析的方法,研究一个区域男男性行为者(MSM)通过互联网交友形成网络社区的社会结构特点。方法采用"线人"调查方式,2016年6月收集百色城区内MSM通过互联网参与的专用Q群和调查之日起3个月内有活动的QQ号,根据结果建立一个Q群与参与活动QQ号的隶属网络矩阵,运用社会网络学分析的整体分析方法,选择中心性的相对结点中心度和相对中间中心度两个定量分析指标,并使用UCINET 6.212软件分析整个MSM参与Q群活动的社会结构特点,使用NetDraw对隶属网络矩阵进行二部图的可视化处理。结果收集百色城区内MSM参与活动的18个Q群和群内4 980个QQ号,汇总后建立一个有18列事件和4 980个行动者的隶属网络矩阵。中心性分析QQ号的相对结点中心度和相对中间中心度中最低数量级行动者所占比例,分别为92.93%和97.65%;Q群中相对结点中心度和相对中间中心度排名前3位的Q群相同,结果分别为L群0.294和0.498、K群0.175和0.318、G群0.103和0.194。生成的二部图显示,18个Q群之间都有一定相同的QQ参与活动,整个网络Q群中L和K群、行动者的q4 980处于对网络信息传播的控制核心地位。结论研究显示,整个城区内MSM依托QQ交友软件,在网络上形成一个等级分化明显又相互联系的社会网络组织结构,当地少数MSM和Q群处于整个网络核心地位,但大城市Q群对当地MSM群体的影响力仅次于当地Q群。可利用以上特点制定相应的公共卫生健康促进策略和方式。Objective To understand the features of social structure of the online community among men who have sex with men（MSM）based on the social network analysis.Methods Information of special QQ groups made up of MSM in Baise was collected in June 2016through＂informers＂,and the relatively active QQ accounts were observed for three months.A database of affiliation network was created according to the information,and then the integral analysis method of social networks was used based on the two quantitative indicators of Nrmdegree and nbetweenness,to know the overall characteristics of the QQ groups＇ social structure.The software UCINET6.212 was used for the analysis.Results An affiliation network base with 18 columns of events and 4980 actors was built based on the 18 QQ groups and 4980 QQ accounts in Baise.The results showed that the minimum quantity of actors in the analysis of Nrmdegree and nbetweenness of the QQ accounts for 92.93% and 97.65% respectively.The Nrmdegree and nbetweenness of top three QQ groups were the same,namely L0.294 and 0.498,K0.175and0.318,G0.103 and 0.194.The final bipartite graph indicated that there was the same level of activity engagement among 18 QQ groups to some degree,and L,K QQ groups and the actor q4980 had a dominant position of the whole network.Conclusion The research indicates that features of the social network structure have obvious differentiation,but are strongly inter-associated.A few local MSM and QQ groups are in the core position of the network while the influence of QQ groups from major cities on local MSM groups is just slightly smaller than that of local QQ groups.All of these results can be beneficial in formulating strategies to promote public health.
