陕南易地扶贫搬迁减贫效应研究——基于分阶段的讨论

Effect of poverty alleviation relocation in southern Shaanxi province

文中以农户总生计资本衡量贫困程度,采用陕南3市9县525户2011、2014、2017三年农户连续跟踪面板数据,利用双重差分模型分阶段研究易地搬迁对农户生计资本的净影响。结果表明:总体来看易地搬迁显著提高了农户总生计资本,减贫效应尤其是即期效应显著;但减贫效应持续性不足,中长期存在边际效应递减趋势;且在不同阶段易地搬迁对农户五种生计资本的影响程度和影响方向存在较大差异。

By utilizing the panel data of 525 households in the southern Shaanxi province in 2011,2014 and 2017,we used the double difference model to estimate the net impact of the relocation on the livelihood capitals of the farmers which is used to measure the poverty level.The results show that:Overall the poverty alleviation relocation has significantly increased the farmers’total livelihood capitals level,the poverty reduction effect is significant,especially the immediate effect.But the poverty reduction effect is insufficient.The trend of decreasing marginal effect exists in the medium and long term.In different stages the impact of poverty alleviation relocation on farmers’five livelihood capitals is quite different.
