Urban Health Resource Supply and Demand Assessment and Clustering Zoning Under Different Transportation Modes Based on MM3SFCA: A Case Study of Harbin, China

The supply and demand levels of urban health resources directly impact residents’ quality of life and health. This study employs the Multi-Mode Three-Step Floating Catchment Area (MM3SFCA) method to assess the supply and demand levels of health resources in the main urban area of Harbin under different transportation modes. To address the gap in previous studies that did not consider the impact of the spatial distribution of health resources at varying distances on residents, K-means clustering analysis was applied. The results indicate a significant imbalance between supply and demand for health resources in Harbin’s main urban area. Specifically, approximately 86% of the population met the supply-and-demand standards for health care facilities. However, only 29% and 41% of the population met the supply and demand standards for physical activity facilities and leisure wellness facilities, respectively. From a transportation perspective, the findings reveal that in areas with balanced or abundant supply and demand, residents primarily rely on driving and public transportation. This suggests that health resources are still concentrated in areas far from residential zones, thereby affecting accessibility to resources for some residents.
