基于互联网公共信息流的区域网络空间结构研究

Spatial Structure of Regional Network Based on Internet Public Information Flow

传统视角下的城市之间的联系多通过要素流动体现。互联网的公共信息,以人的诉求为导向,遵循市场供需原则,数据具有较强的客观性、易获性和实时性,更能体现和预测城市之间关系。通过"58同城网",对武汉2小时高铁圈覆盖城市进行公共信息提取和分析,对其区域网络空间结构展开研究。结果表明:(1)该区域信息流空间具有典型的层级体系特征:依据信息流总量,分为积极、消极和信息边缘城市。(2)信息流视角下,基于传统的中心地理论的圈层式区域空间结构形态被打破,地理邻近效应减弱,主要城市之间跨区域联系增强,呈现出多中心网络空间形态。(3)信息联系和城市综合实力正相关,与代表知识和技术的软实力高度相关,武汉作为信息网络控制性节点的作用将进一步凸显,游离在信息网络之外的城市将更加边缘化。

The connection between cities is reflected through the flow of elements from traditional perspective. Public information on the internet is oriented by people＇s appeal and followed the principle of market supply and demand. The data is objectivity, accessible and real-time, that can well reflects and predicts the interaction between cities. Based on the data collected from ＂58 city network＂, this paper analyzes the public information of Wuhan city and its surrounding area, which is covered by 2 hours high speed railway network. The results show that： （1） the space of information flow is characterized by a typical hierarchical system in this region： according to the total amount of information flow, it can be divided into positive, negative and marginal cities. （2） from the perspective of information flow, the shape of the circle regional spatial structure is broken. When the geographical proximity effect are weakened, the regional links between main cities are enhanced. At the same time, this area presents a form of multi-center spatial network. （3） information linkage and the city＇s comprehensive strength are positive correlation, is highly correlated with the soft power on behalf of knowledge and technology. Wuhan will be further highlighted as an information network control node role. The cities will be more marginalized which are excluded from the information network.
