摘要: 利用中国家庭追踪调查数据(CFPS),构建相对贫困家庭的医疗经济风险预期对家庭医疗负担反应差异的面板门槛模型,发现相对贫困家庭的灾难性医疗支出标准为医疗支出占除食品、教育及居住等其他支出的21.02%;继而建立空间计量Tobit杜宾模型和空间Tobit杜宾中介效应模型,分别实证检验了灾难性医疗支出以社会网络为媒介在相对贫困家庭间的空间传导机制,以及医疗保障制度对相对贫困家庭灾难性医疗支出空间的影响机制。研究表明:通过社会关系影响转移性支出压力和社区家庭健康水平,灾难性医疗支出可以在相对贫困家庭间的传导,但是医疗保障制度能够有效缓解相对贫困家庭间转移性支出压力和提高整体家庭健康福利,从而阻断了灾难性医疗支出在相对贫困家庭间的传递。

Abstract: By making use of the data of China Family Panel Studies (CFPS), this paper constructs a panel threshold model of the response differences in the medical economic risk expectations to family medical burdens of relatively poor families. The findings show that the standard of catastrophic medical expenditures of relatively poor families is that medical expenditures account for 21.02% of other expenditures except food, education and housing. Then it constructs a Tobit Durbin model of spatial metrology and a spatial Durbin Tobit mediation model to empirically test the spatial transmission mechanism of catastrophic medical expenditures among relatively poor families with social networks as medium and the spatial impacting mechanism of medical security system on catastrophic medical expenditures of relatively poor families respectively. These findings suggests that, by influencing the transfer expenditure pressure and the health level of community families through social relations, catastrophic medical expenditures can be transmitted among relatively poor families. However, the medical security system can effectively alleviate the transfer expenditure pressure among relatively poor families and improve the overall health welfare of community families, thus hindering the transmission of catastrophic medical expenditures among relatively poor families.

Key words: catastrophic medical expenditures, relatively poor families, the spatial transmission mechanism, the spatial Durbin Tobit model
