目的:认识我国城市贫困人口医疗救助系统复杂结构的演化过程和主体行为特征。方法:用流率基本入树建模法构建系统流图,用VENSIM软件进行模拟分析和干预。结果:成功模拟了系统运行的趋势并找到了系统干预的关键点。结论:城市贫困人口医疗救助系统是复杂系统,明确其运行规律有助于政策的制定以及进一步推动城市贫困人口医疗救助体系的完善。
OBJECTIVE: To understand the evolution of the complex structure of the medical aid system for the urban poor in China and its main behavioral characteristics. Methods: The system flow diagram was constructed by using the flow rate basic tree modeling method, and the VENSIM software was used for the simulation analysis and intervention. Results: The trend of system operation was successfully simulated and the key point of system intervention was found out. Conclusion: The medical aid system for the urban poor is a complex system. It is helpful to formulate the policy and clarify the operating rules of the urban poor and to further improve the medical aid system for the urban poor.
