Abstract：Objective:To deconstruct the overall medical expense and analyze systemic characteristics of cost structure dynamics in China from the perspective of optimizing healthcare resource allocation.Methods:Utilizing hospitalization records in a sample city from 2022-2023 as the research literature,the linear regression models for different cost components was established over the two-year period within each DRG-based case group to identify statistically significant temporal trends and directional changes in cost structures.Results:Most DRG groups exhibited significant trends in at least one cost component.Notable concentration patterns emerged in medication,comprehensive care and therapeutic service costs.When evaluating structure improvement,most achieved optimized allocation in at least one major cost component.Conclusion:The sample city demonstrates continuous optimization in healthcare cost structures,yet specific cost categories and DRG groups deviated from resource allocation optimization goals.Policy interventions should prioritize granular,DRG-specific adjustments to address heterogeneous structural dynamics.
