Abstract:

Informatization, networking and globalization have intensified the important role of information elements to the regional development, and therefore research on information space from the perspective of information element is significant to regional information development and can help the government make scientific decisions for information development and information industrial layout. In this paper, a new method of information space measurement based on internet information flow is established. According to the new method, information spatial networks respectively based on internet flow rate and flow speed are discussed and complex network analysis is used to explore the character of information space distribution pattern. With the tool of social network analysis, overall network structure, cohesiveness and centrality are researched. Thus, the provincial information loop, information nuclear and information field are identified in this paper. Furthermore, the whole network model, the trunk network model and the backbone network model are respectively discussed. Some core and important provinces are found out from the perspective of the hub - network. Some results can be obtained as follows. The information space shows a "heterogeneous" trend, decreasing from east to west. The information influence of provinces presents an eastern-central-western tiered decreasing trend. The core provinces of the information space are mainly located in the eastern coastal developed regions, which are the potential area of the information development. National development strategies such as the integrated development strategy of Beijing, Tianjin and Hebei and the reconstruction of the Silk Road have a certain influence on the spatial distribution pattern of information space. Beijing, Tianjin, the Yangtze River Delta and Pearl River Delta regions are the core area of information space. What's more, some eastern provinces and Beijing, Shanghai and Guangzhou connect the north, the south and east of China, which forms a stable "triangle pattern". As the backbone of the western provinces, Sichuan and Inner Mongolia cross the western region from the south to the north, driving the development of western information space with the pattern models of "one axis and two dots". At the same time, the powerful mobility of information space makes up the separatist nature of physical space, weakening the constraints of space and artificial isolation, reducing the communication costs and improving the accessibility in the traditional sense. However, we find that the information spatial pattern of China at this stage is not completely out of the constraints of geographical space, but, to a certain extent, still partly dependent on geographical distribution.
