【摘要】：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。
[Abstract]:The connection between cities from the traditional perspective is mostly reflected by the flow of elements. The public information of the Internet is guided by the demand of people and follows the principle of market supply and demand. The data is objective, easy to obtain and real-time. It can better reflect and predict the relationship between cities. Through "58 with the city network", the public information extraction and analysis of the two-hour high-speed rail circle covering the city in Wuhan are carried out. The results show that the regional information flow space has typical hierarchical system characteristics: according to the total amount of information flow, it can be divided into positive, negative and information marginal cities. Based on the traditional central land theory, the regional spatial structure of the ring type is broken, the geographical proximity effect is weakened, and the cross-regional connection between the major cities is strengthened, showing a positive correlation between the information connection and the comprehensive strength of the city. As a controlling node of information network, Wuhan will play a more important role in the soft power of representing knowledge and technology, and the cities outside the information network will be more marginalized.
