农户因病致贫的动态变化及其影响因素分析

Analysis on dynamic changes and the affecting factors of poverty caused by illness in rural China

根据2009年和2011年中国营养与健康调查数据,通过构建双变量Biprobit模型,分析了中国农村家庭因病致贫的动态变化及其影响因素。结果表明:农户因病致贫并非暂时性冲击,而是对家庭未来贫困具有显著的动态影响,因病致贫农户在未来两年内陷入贫困的概率至少是非贫困农户陷入贫困的2.2倍;农户脱贫主要依赖农民收入的获取能力及家庭资源,外出打工、家庭人均耕地面积、家庭男性劳动力比例对农户脱贫具有显著影响,农户家庭规模越大越容易陷入贫困;家庭成员的健康状况对农户贫困具有显著的正效应。

we used data of China Health and Nutrition Survey(CHNS)from2009to2011and Biprobit model to analyze dynamic changes and the affecting factors of poverty caused by illness in rural China.The results showed that:Illness-induced poverty had significant,non-temporary dynamic influence on poverty in rural China,and the probability to fall into poverty was2.2times for household with illness-induced poverty of that of the non-poverty household;poverty alleviation mainly depended on the acquisition ability of farmers'income and family resources,working out,the per capita cultivated land area of the family and the proportion of family male labor force had a significant influence on the poverty reduction,while household with bigger size had more chance to fall into poverty than others;the health status of family members had a significant positive influence on poverty.
