In the context of rapid aging, the demand for old-age care services in the elderly is increasing day by day, and the problem of “one bed is hard to find” is found in the allocation of urban old-age facilities. Compared with the increase of the scale of allocation, it is more important to explore the spatial configuration of old-age facilities space in terms of spatial distribution of urban old-age facilities and their structural characteristics. Therefore, in the crossing field of urban and rural planning and complex sciences, it employs the complex network analysis principles and methods, selects the old-age facilities of Yuzhong District, Shapingba District, Nan’an District, Jiulongpo District in Chongqing(hereinafter referred to as the four districts) as samples to construct old-age facilities supply network model, build evaluation index system, and combined with comprehensive bed utilization analysis of old-age facilities, it illustrates the spatial structure of old-age facilities. It is concluded that the overall stability of the urban old-age facilities in Chongqing is poor, and the supply and demand imbalance of the oldage facilities is due to the single type of configuration and the dislocation of the supply pattern. This paper puts forward the corresponding optimization strategy for the planning, and provides scientific basis for the special planning and optimization of the old-age facilities.
