摘　　要：为提升政务微博信息传播效率和应对突发事件的能力,文章以新浪微博政务排行榜中部分政务微博为研究对象,从小世界和结构洞理论视角对政务微博的信息传播效率进行了实证研究。研究结果表明,案例形成的社群图网络密度小,不利于政务信息的有效传播;政务微博信息传播网络具有明显的小世界性质,处于"中转站"或"端点"位置的节点具有长程连接作用,有利于政务信息传播;公安部门和旅游机构类政务微博与其他政务微博的联系较为紧密,这两种类型的微博扮演着"意见领袖"角色,对提高网络中政务信息的传播具有促进作用。To improve the effciency of information dissemination and the ability to deal with emergencies of the government micro blog, the paper takes some of the popular government micro blogs in Sina as the research object and makes an empirical study on the effciency of information dissemination between the government micro blogs. The research results shows that the network density of the social graph on the government micro blog network is low, which is unfavorable to effectively disseminate the government information. The information dissemination network of the government micro blog has obvious small world characteristics and the nodes in the “transit station” or “endpoint” position have the long distance connection function, which are conducive to government information dissemination. The public security departments and the tourism agencies such micro blogs and other government micro blogs contact more closely, these micro blogs play the “opinion leader” role and they have a promotion function to enhances the network of the government information dissemination. At last, the paper puts forward some pertinent suggestions according to the research conclusion.
