不同综合门户网站首页新闻评论者的时空分布对比--以新浪和网易为例

摘要

在信息与通信技术特别是互联网技术作用下，传统的地理学空间研究包括空间形态、地理事物和时空分布规律都发生了重大变化。网络空间中信息随时间的空间扩散和空间分布规律是相关研究的一个重要切入点。选择不同综合性门户网站首页的同一条新闻，具体分析新闻评论者的时空分布特征及其影响因素。研究发现：①新浪和网易两个门户网站新闻评论者的时空分布差别很大；②无论是对于新浪还是网易而言，其新闻评论者的空间扩散最初都是“散点式”扩散模式，之后呈现出“不完全填充式”扩散特征；③新闻评论者的空间分布存在典型的地域差异；④新浪和网易新闻评论者的空间分布是具有地理根植性的，网民数量、GDP和城镇人口是影响其省级行政区分布的重要因素；⑤网站平台、网民上网习惯、时间和上网工具也是影响新浪和网易新闻评论者时空分布的因素。%Under the effect of information and communication technologies, es-pecially internet technology, the traditional research of geographic space which includes space form, geography things and time-space distribution regu-larities has changed. In order to study time-space distribution regularities of information dissemination ?in cyberspace,we proposed a new research method through news commentators' location information. Because Sina and NetEase both provided more accurate news commentators' location information, we chose them to carry out further study. In practical terms, we selected the same news in Sina and NetEase homepages’important news section as the research object and analyzed the space-time distribution of comment authors and its influential factors. This research indicates that: ①The space-time distribution differ-ence of news commentators in Sina and NetEase is very huge. ②Whether it is for Sina or NetEase, Spatial diffusion of news commentators are the diffusion model of scattered –point during the initial period, which means that it can quickly spread to several parts of the country in a very short time. After this initial period,spatial diffusion of news commentators then presented the diffusion model of non-full fills diffusion, which means that with the in-volved area is increasing,the most of the provinces in the final did not achieve full coverage. The space distribution of news commentators is not in line with the range attenuation law in traditional geographic, featured with crossing the space length in reality. ③Spatial distribution of news commenta-tors is imbalance, namely the existence of a typical regional differences. The imbalance is not only existing among the four regions or the different provinces,but also includes diffusion index and number of news commentators.④Fictitious cyberspace is not the hyperspace that is completely isolated from the actual geographical space.The provinces distribution of news commentators on Sina or NetEase has geographic embeddedness and internet users, GDP and ur-ban population are important factors affecting provinces distribution. ⑤There are many significant factors that influence the space-time distribution of comment authors such as website platform,behavioral habit of Internet users, time and internet equipments.
