摘要
基于国务院发展研究中心2015年和2016年'中国民生问题'入户调查数据,运用Heckman两步法考察城乡基本医疗保险补偿率对居民就医决策及医疗支出的影响;在此基础上,运用Blinder-Oaxaca分解法,对影响城乡居民医疗支出差异各因素的作用进行分解。研究发现:基本医疗保险补偿率增加会显著提高城乡居民的就医概率,增加医疗支出;基本医疗保险补偿率对城乡居民医疗支出的影响存在显著的收入异质性,不同收入组居民的医疗支出对补偿率变化的敏感性存在明显差异;城乡基本医疗保险补偿率差异对居民医疗支出差异的贡献率为14.37%,低于城乡收入差异,高于医疗卫生资源供给差异。
Based on the'China Livelihood Survey'datasets in 2015 and 2016,the paper first examines those factors that have effects on the demand for medical service of the residents using the Heckman two-step.Then,the Blinder-Oaxaca decomposition method is employed to measure the contribution of factors to the inequality of medical expenditure between the urban and rural areas.The main results can be summarized as follows:firstly,the addition of insurance compensation ratio will increase people’s probability to utilize the medical service and the medical expenditures.Secondly,the effects of compensation ratio on the medical expenditures is heterogeneous largely to the different income ladder,as the higher in the ladder,the more sensitive of medical expenditure to the compensation ratio.Thirdly,as to the contribution to the inequality of medical expenditure,the disparity of insurance compensation ratio is 14.37%,which is lower than the gap of income yet higher than public health resource.
