网络信息空间的空间关系及信息流研究为信息化影响下的地理空间演变研究奠定基础。借助微博这一新兴网络信息传播平台获取中国城市间网络信息联系数据，采用流分析方法呈现城市间网络信息联系的空间格局。研究发现：中国城市网络信息关系呈现出“一超多强”的空间极化不对称格局。网络空间不对称格局与地理距离、经济社会发展水平存在密切关联性，表现为：城市对外网络信息总不对称度与其经济社会发展水平的相对一致性；经济社会发展差距对城市间网络信息不对称程度影响的距离衰减性；城市间网络信息不对称程度与经济社会发展差距的相对一致性；东、中、西部三大地区间网络信息不对称关系与经济发展梯度的相对一致性。

The study of spatial relations and information flows in cyberspace lays the foundation for the study of geospatial evolution under the influence of ICTs. Information flows among several cities can be obtained through the microblog platform. The research deals with statistics collected from Sina micro-blog as follows. First, select 51 representative Chinese cities to a certain standard taking the easy access of research data into account. Second, select 20 Sina micro-blog users in each of these 51 cities and record their geographical attribute statistics. Then analyze Internet information contacts state and spatial configuration among these Chinese cities from the perspective of geography. This paper uses the flow analysis to project the abstract spatial relations on the concrete geographical space and compare the spatial configuration of Internet information contacts among Chinese cities with the spatial pattern of regional economic and social development so as to explain the formation mechanism. The results demonstrate that: The Internet information relations among Chinese cities present a “one superpower and many” polarized spatial asymmetric configuration. The information asymmetric configuration in cyberspace has close correlation with the distance and the social and economic development levels in geographical space, which expresses as: The Internet information asymmetric degree of one city to the others is relatively consistent with the economic and social development levels of it; With the distance between two cities rising, the impact of the economic and social development gaps on their Internet information asymmetric degree will reduce; At a certain distance, the Internet information asymmetric degree between two cities is relatively consistent with their economic and social development gap; The Internet information asymmetric relations among the eastern, central and western China are relatively consistent with their economic and social development gradient.

Key words: Geocyberspace, Spatial relations, Information asymmetry, Micro-blog, City and region
