关于中国贫困的动态多维度研究

文章利用中国健康与营养调查8个调查年度的数据,基于能力方法的视角,选用收入、教育和生活质量3个维度,对中国的贫困状况进行了动态多维度考察,结果发现:(1)相对于单一的收入贫困,多维贫困程度更为严重、波动性更大,贫困人口应对外部冲击的脆弱性明显,其中教育贫困尤其严重。(2)尽管农村与城市之间收入贫困趋于收敛,但近年来农村多维贫困对全国的贡献度高达80%以上,城乡间多维贫困差异有不断扩大的趋势。(3)指标等权重情形下的多维贫困随时间推移呈平稳快速下降态势,其中生活质量改善对多维贫困下降的贡献度最大。(4)就影响多维贫困的外在环境因素而言,东部地区的多维贫困下降明显快于其他地区,家庭中劳动力及户主的特征也对多维贫困产生显著影响。文章探讨了多维贫困的致因和消除多维贫困的政策选择。

A Study On the Dynamic Multidimensional Measurement of China's Poverty

With a Capability Approach and data from CHNS(1989-2009),this paper chooses three dimensions-income,education and quality of life to measure China's multidimensional poverty dynamically.The outcome shows that:(1)Versus single income poverty,poverty status from multidimensional measurement is much more severe and fluctuating,and the poor is vulnerable to external shock,especially those of education poverty;(2)Although income poverty converges between rural and urban,rural multidimensional poverty gives an ov...
