Abstract: Based on the gravity and passenger shift among cities and towns in Zhejiang province, this paper builds the urban linkage network, then uses the methods of social network analysis and comparative analysis to research the network characteristics from the perspective of the grades of point, line and network. The result is that: Hangzhou municipal district has the largest external linkage, and the following two are Ningbo municipal district and Wenzhou municipal district. The scale classification of external linkage is particularly obvious, but the scale distribution of passenger linkage is more homogeneous. The spatial distribution of node scale based on two methods shows that the north is high and the south is low, while the middle is a prominent area. The spatial distribution based on first and second linkage shows that the geographic segmentation complies with the form of center-radiation. However, there are differences between the two methods, the strong linkages mostly distribute among the regional center and towns circling them. Simultaneously, the density of urban network in Zhejiang province is still low, but the control force of Hangzhou municipal district and Ningbo municipal district is stable, which presents an inadequate coordinating network. Aiming at current situation, this paper suggests that the governments should optimize urban scale system and broaden ways of communication and cooperation between cities and towns.
