Abstract: The inequity of access to healthcare services is still one of the most long-lasting problems confronted by worldwide countries. Under such context where maldistributed healthcare resources have posed huge challenges in achieving cross-regional efficiency and equity of healthcare services, rational allocation of newly added healthcare resources has become rather critical to policy makers. To address this issue, we applied a two-step optimization approach to investigate the spatial allocation of newly added tertiary general healthcare resources in Chengdu, a metropolitan city of China. The case study of Chengdu was utilized as an example to illustrate the feasibility of such spatial optimization approach in practice in terms of supporting regional health planning related decision-making procedures in China, as well as evaluating the performance of healthcare resource allocation related strategies actually implemented. Using current and historical health planning data, we sought to optimize tertiary general hospitals’ locations to maximize population coverage of healthcare services in the first step, and to achieve equitable access to healthcare services among different residential locations via assigning the capacity (beds) to each hospital in the second step. Results suggested that the spatial optimization of newly added healthcare resources would theoretically enhance both efficiency and equity substantially. Specifically, if implemented in practice, such optimized spatial allocation of healthcare resources would theoretically contribute to improved efficiency as reflected by a 5% increase and a 15% increase in population coverage and the weighted median value of spatial accessibility, respectively. In addition, this would contribute to achieve enhanced equity as reflected by a 27% decrease in the weighted standard deviation of spatial access. These findings are anticipated to offer valuable policy implications to inform the spatial allocation decisions of healthcare resources in China as well as other countries confronted with similar challenges, and the two-step optimization approach could be applied to facilitate future rational health plannings.
