我国农村贫困线的测定——基于营养视角的方法

Estimating Rural Poverty Line in China: An Alternative Method in Perspective of Nutrition

农村贫困线是估计农村贫困程度和规模的重要尺度。即使到目前,视贫困线为维持人们基本生存所必须消费的物品和服务的最低费用的观点仍具有现实意义。基于该原则,从贫困最基本的测度指标食物营养出发,本文利用Matlab软件,基于我国1985—2009年部分年份农村居民收入分组数据,对农村贫困线重新进行了模拟和测算,与其他一些研究结论类似,测算结果表明,之前我国公布的农村贫困线标准长期偏低,农村贫困人口规模有所低估,但2011年11月19日最新公布的贫困线标准缩小了与本文测算结果之间的差距。

Rural poverty line is the crucial rule for estimating the poverty depth and population. Even at present,the view has practical meanings to regard poverty line as the minimum level of expenditure on the amount of the minimum charges of the necessary living goods and services for satisfying people's basic needs of minimum survival. Based on such principle and statistical income data of rural household groups over the period of 1985-2009,the paper simulates and estimating rural poverty line in China using the fundamental poverty measure index namely food nutrition and the Matlab software. Similar with previous research conclusions,our results indicate that for a long time both the poverty line and poor population in rural China has been underestimated. However,the gap between the new poverty line issued on November 19,2011 and the poverty line estimated by us has narrowed largely.
