贫困门槛地区调整与农村贫困趋势测算

摘要： 文章在现有的CHNS调查数据基础上,首先测算地区生活成本指数,然后采用地区生活成本指数调整固定贫困门槛,测算和比较不同贫困门槛下各地农村贫困趋势的变化。结果发现:地区价格水平高于全国平均价格水平的地区,按照固定贫困门槛度量低估了农村贫困程度;地区价格水平低于全国平均价格水平的地区,按照固定贫困门槛度量高估了农村贫困程度。建议未来在依据固定贫困门槛度量各地贫困程度的基础上,通过经地区生活成本调整的贫困门槛建立补充贫困趋势序列,为客观认识各地区的农村贫困状况提供参考。
Based on the existing CHNS survey data, this paper calculates the regional cost of living index firstly, and then uses the regional cost of living index to adjust the fixed poverty thresholds, calculating and comparing the changes in the rural poverty trends across the different poverty thresholds. The results show that in areas where the regional price level is higher than the national average, the rural poverty level is underestimated according to the fixed poverty; if the regional price level is lower than the national average price level, the rural poverty degree is overestimated according to the fixed poverty threshold measurement. The paper suggests that on the basis of measuring the poverty degree of each region according to the fixed poverty threshold in the future, a supplementary poverty trend sequence be established through the poverty threshold adjusted by the regional living cost, so as to provide a reference for the objective recognition of rural poverty in each region.
