Abstract The multi-level perspective city network is of great significance in understanding spatial interaction and linkages. Based on inter-city startup investments data, this study offers a new perspective to identify the spatial structure of China's city networks from node- to linkage-level, and further explore the organization patterns from sub-network-level. This study can deepen the understanding of city network structure under the effects of city hierarchy and distance decay. The results are shown as follows. At the node-level, the distribution of startup investments is uneven and highly concentrated in megacities and municipalities. Moreover, the rank-size distribution of startup investments tends to be more monocentric than that of population and GDP. At the linkage-level, first, the city network based on startup investments has an obvious hierarchical structure, and the connections between Beijing, Shanghai and Shenzhen are the strongest and form a triangular framework. Second, inter-city startup investments are mainly flowing within the same industry, and the service industry owns the most outflows and inflows. Third, inter-city startup investments display distance decay, but high-hierarchy cities can break the distance constraint. For example, the linkages are close between the three urban agglomerations with Beijing, Shanghai and Shenzhen as the cores. At the sub-network-level, seven communities are identified through community analysis, and we suggest that the community boundaries have two spatial characteristics including administrative district economy and the spillovers from high-hierarchy cities. Additionally, the organization patterns of communities are various, including single-core; single-core and multi-pairs; double-core and multi-pairs; and multi-core patterns. Compared with the existing research for other perspectives of city network, there are two new findings in our study.
