中文摘要：

文章基于1989—2009年“中国健康与营养调查（CHNS）”八次入户调查数据，实证检验了政府救助对居民户贫困状况的影响效应。研究结果表明：政府救助资金因挤出了私人救助资源并“诱导”低收入居民更加依赖于政府救助而未能有效发挥减贫作用。平均而言，1个单位政府救助将挤出0．39个单位私人救助资金，并诱导低收入群体降低2．71个单位工作收入；同时对于贫困程度更深的居民户，“挤出效应”和“诱导效应”都更加严重。而社会医疗保险等保障性公共服务能够直接和间接发挥缓解贫困作用。为了帮助低收入者走出贫困，政府由单纯的贫困救助转向为低收入群体更好地提供保障性公共服务将是一种有效的政策选择。

英文摘要：

Based on the data of CHNS from 1989 to 2009,this paper empirically studies the effect of government assistance on household poverty.The results show that： the government assistance funds could not relieve poverty effectively because the private assistance resources are crowded outand the poor are induced to more depend on government assistance. On average,one unit of government assistance will extrude 0. 39 unit of private asistance funds and reduce 2. 71 units of work income of the poor further- more, the crowding-out and inductive effects are more serious threats to thepoorer. And the security public services like social health insurance could effectively alleviate poverty by direct and indirect channels. Therefore, it willbe a more efficient policy choice to provide the poor with the security public services combined with government assistance in order to help to protect thepoor from poverty.
