Abstract：Based on the 1‰ microdata from 2015 1% population sample survey and the Tencent location migration big data in 2018, this study uses complex network analysis method to compare the spatial structure and organization mode of city networks from the perspective of long- and short-term population flows in China, in terms of nodes, flows, first connections and community structure. The results are as follows: 1) Both long- and short-term floating population tend to cluster in a few large cities, when considering network direction, city nodes are given different functions and roles. 2) Both long- and short-term population flows are mainly distributed in the southeastern half of the Hu Line. 3) Both networks exhibit the dual characteristics of adjacent connection and preferential connection, but large-scale and high-intensity first connections in long-term human mobility network are dominated by adjacent connection. 4) Both networks have obvious community structure, but the long-term human mobility network is dominated by cross-provincial adjacent combination type, reflecting a“clustered”community structure.
