我国农村贫困分解及组群研究

近20年快速的经济增长对我国减贫作用显著，但由于农村与城镇在居民收入、分配政策上的差异，农村贫困改善的速度低于城镇，更加突出其在我国减贫工作中的重要性. 本文并非拘泥于现有地域特征划分依据，而是利用SST贫困综合测度指标的分解维度，创新性地提出按照贫困特征指标进行组别的划分，从而使我国农村贫困组群划分更科学合理. 继而，本文采用CHNS数据库中我国农村9省的调研数据，对其进行组群分类研究；并通过FGT指数及其差异分解结果验证了分组结论的有效性. 最后，结合分组及指数分解结果总结归纳出我国农村贫困的组群特征及差异原因，为针对不同组群提出更有针对性的减贫措施提供参考.

Rural poverty decomposition and group study in China

Nearly 20 years of rapid economic growth has a significant impact in poverty reduction in China. However, rural districts show slower improvement due to the difference in individual income and distribution policy between rural and urban regions, which emphasizes the importance of rural distincts in poverty reduction in China. This paper is limited to neither geographical division nor economic zoning, but creatively utilizes the decomposition of SST index to group the provinces in a 3-dimensional space, that is, to group the provinces according to their performance and characteristics in poverty, aiming to make the division of rural poverty group more reasonable. We carry out the group study basing on the CHNS rural data of 9 provinces, and further prove validity of the division by Shapley decomposition of FGT index differences. Take into consideration the characteristic of rural poverty groups and sources of differences, we suggest specific measures be taken for poverty reduction of different groups for reference.
