代际贫困是贫困代际转移的产出，是收入分配不公的重要表现。本文基于CHNS数据对我国代际贫困表现和特点进行了统计描述，发现按照2美元的国际贫困线标准，我国的代际贫困现象比较严重。其次，建立计量模型揭示了贫困代际转移的概率，代际收入弹性约为0．8，表明我国的社会流动性低于发达国家。

英文摘要：

The intergenerational poverty is the output of intergenerational transmission of poverty and is the important manifestation of unfair income distribution. The paper statistically describes the feature of intergenerational poverty in China. The results show the intergenerational poverty is severe. Secondly, the paper establishes econometric model to measure the probability of intergenerational transmission of poverty. The intergenerational earnings elasticity is approximately 0.8, which shows the social mobility is weaker than developed countries. At last, the model also suggests that the modern education＇s influence to promote the role of intergenerational mobility in China is very weak.
