【摘要】 互联网信息的发展形成了虚拟的网络社会.分析信息空间网络在传播过程中的空间分布规律以及网络结构,可以深化信息流在空间传播中的研究.文中利用社会网络分析法和重力模型,在社会地理学视角下尝试对微博中某次疫苗事件信息的传播路径进行有向网络的构建,并进行定量分析.研究发现:1)信息传播具有地域性,中国不同的地域都会形成“中心岛”城市,这些城市主导着周边乃至全国范围内的舆论方向;2)相同时间段内的舆论信息传播路径数量在空间分布上呈现出不对称性,东部地区比中部和西部地区密集;3)在事件发生地区,内部节点主要起到中间点传播舆情的作用,并不能很好地引导舆情的走向. 文中的研究结果可以为社会网络发展和舆论引导提供理论依据.更多还原

【Abstract】 The development of internet information has formed a virtual network society.Analyzing the spatial distribution law and network structure of the information space network in the propagation process can deepen the research on information flow in space communication.By using the social network analysis method and gravity model,from the perspective of social geography,this paper attempted to construct a directed network for the information propagation path of‘Shandong illegal vaccine event’in micro-blog and make quantitative analysis.The research findings are as follows.1)Information propagation has regional characteristics,and different regions in China will form "center island"cities,which dominate the direction of public opinion in the surrounding areas and even in the country.2)In the same period of time,the number of public opinion information transmission path presents asymmetry in the spatial distribution,and the eastern region is more intensive than the central and western regions.3)In the event area,the internal nodes mainly play the role of spreading the public opinion at the intermediate point and do not guide the public opinion well.The results of this study can provide a theoretical basis for the development of social networks and public opinion guidance.更多还原
