Abstract
In the context of “space of flow”, urban interaction has become the key force impacting urban landscape evolution and urban sustainable development. Current research on urban interaction analysis is mainly conducted based on the interaction of geographical elements, the virtual flow of information in cyberspace has not been given sufficient attention, particularly the information flows with explicit geographical meaning. Considering the dramatic population migration and the explosive growth of cyberspace in China’s main urban agglomerations, we constructed the information flow of migrant attention (IFMA) index to quantify the urban information interaction derived from public migrant concern in cyberspace. Under the framework coupling spatial pattern analysis and spatial network analysis, exploration spatial data analysis (ESDA) and complex network analysis (CNA) were adopted to identify the urban interaction features depicted by IFMA index in the three main urban agglomerations in China. The results demonstrated that, in the study area: (1) The IFMA index presented a reasonable performance in depicting geographical features of cities; (2) the inconformity between urban role in the network and development positioning confirmed by national planning existed; (3) in the context of New-type urbanization of China, urban interaction feature can be a beneficial reference for urban spatial reconstruction and urban life improvement. Using the cyber information flow with geographical meaning to analyze the urban interaction characteristics can extend the research angle of urban relationship exploration, and provide some suggestion for the adjustment of urban landscape planning.

In the context of globalization and production fragmentation, cities are no longer islands and have begun to exploit scale economies in complementary relationships and synergies in cooperative activities.The pattern, which relies solely on internal know-how, does not fit in this development stage and brings the presence of “market failure” [1]
To investigate the urban interaction features expressed by the information flow with meaning in cyberspace, the information flow of migrant attention (IFMA) index was constructed, and exploration spatial data analysis (ESDA) and complex network analysis (CNA) were employed geographical meaning in cyberspace, the IFMA index was constructed, and ESDA and CNA were to explore its characteristics in terms of spatial patterns and spatial networks
We endeavor to identify urban interaction features expressed by the information flow in cyberspace, to extend the research angle of urban interaction and provide more references for the enacting of regional policy in the three main urban agglomerations of China
Summary
In the context of globalization and production fragmentation, cities are no longer islands and have begun to exploit scale economies in complementary relationships and synergies in cooperative activities.The pattern, which relies solely on internal know-how, does not fit in this development stage and brings the presence of “market failure” [1]. Under the continuous construction of high-speed interactive passages, intercity interactions expressed by the flowing of populations, materials, information, techniques, capital, etc., has been reinforced. This brings the achievement of urban economies of agglomeration [2]. External influences, accompanied by the activities of interaction between cities, merged into the process of urban development and promoted the form of urban organization mechanism in a networked and linked way. In such a context, the influence of urban interaction is
