本文运用有序特征群体分布曲线和系数比较分析了两个历史时点样本地区人群医疗费用的分布。研究发现:(1)就诊费用出现了向较高收入人群转移的趋势;(2)住院费用则出现了向较低收入人群转移的趋势,加重了低收入人群因病致贫可能。研究建议采取有力措施切实加强农村地区低收入人群的医疗保障水平。
This paper compares the distribution of medical expenses among the populations in two sample locations at a historical time point by using the population distribution curves and coefficients of ordered features. The study found that: (1) there is a tendency for medical expenses to shift to higher-income groups; (2) hospitalization costs tend to shift to lower-income groups, which increases the likelihood of low-income people becoming impoverished due to illness. The study recommended that effective measures be taken to effectively strengthen the level of medical insurance for low-income people in rural areas.
