摘要
由于医疗费用数据的特异性,学者提出了样本选择模型和两部模型来验证年龄、距离死亡时间(TTD)对医疗费用影响。本文比较了两种方法的差异,并综述了国际上主要研究结果。多数学者认为,TTD对医疗费用有影响,且影响程度大于年龄的作用。提示老龄化会造成医疗费用的增长,但由于终末期医疗费用一生只有一次,老年人数量增长导致的费用增加可能小于预期。
Due to the specificity of the medical expenditure data, scholars have proposed the sample selection model and the two-part model to test the impact on medical expenditure by age and time to death. The two kinds of methods were compared, the independent variables and main research results were listed. Most scholars suggested that TI？D rather than age was a more important factor of medical expenditure. According to the review, aging contributed to the growth of medical expenditure but the contribution may lower than traditional expectation since death occurs only once in every life.
