中文摘要：

本文利用抽样调查数据，分析农户参与新型合作医疗情况、从中获益情况和对新型合作医疗制度的评价三个方面，以此对新型合作医疗的可持续性进行研究。研究结果表明，农民参与新型合作医疗的程度较高，但是，由于被调查地允许农民以个人参加，导致新型合作医疗存在严重的“逆选择”现象，违背新型合作医疗制度“农户以家庭为单位参加”的政策设计。另外，农户从新型合作医疗得到的报销比例太小，农户对新型合作医疗的评价不高都会影响该项制度在农村的实施和可持续发展。

The aim of those analysis is to assess the sustainability of NCMS. The case indicates that, the farmers are willing to participate the NCMS. But there are still three situations which can affect the sustainability of the NCMS： （ 1 ）because the investigated permits individualparticipation, the systems exist serious ＂counter choice＂, and this violates ＂family-participation＂ policy design. （2） Moreover, the peasant obtains from the systems too little. （3）the peasants gave bad evaluation to the system.
