Based on the interlocking network model and the complex network theory, this paper analyzes the spatial distribution and interaction of cities based on geographical distribution of equipment manufacturing enterprises. The study indicates that cities all over the country present a hub-network structure. Beijing is the national hub city of the network. Cities such as Shanghai, Shenzhen, and Chongqing are regional hub cities. Beijing and Shenzhen have the strongest intercity connection in the network. Most cities in the northwest and southwest have a relatively low connection with other cities in the network. By comparing the sub-networks of different industries, it is found that there are significant differences in network scale, hub city and network density, which proved the polycentricity and diversity of urban space organizational hub-network structure. Finally, complex network theory is used to deliver deliberate attack experiments. The experimental results show that the network connectivity is basically not affected when the hinterland of the hub city is deleted, while the network connectivity declines obviously when the non-hinterland of the hub city is deleted. This indicates that the restriction of spatial distance between hubs and nodes is getting weaker, which is significantly different from the central-hinterland structure.
