| 内容提要 | 本文基于中国珠三角地区实地调查数据，考虑到样本选择偏误和收入数据的分段有序性，采用样本选择有序模型（Ordered Model with Sample Selection），从四个维度考察影响农民工收入的决定因素，包括：家庭特征、人力资本、社会资本和外部制度特征。尤其是，本文将社会资本分为“整合型”和“跨越型”展开分析。半参数估计结果研究表明，“跨越型”和“整合型”社会资本对农民工收入都具有显著的正影响，但“跨越型”较“整合型”社会资本对农民工收入的提升效应更强。在企业内，农民工与当地员工建立友好关系比没有这种和谐协调关系将使农民工挣得中高收入的可能性增加24%；来自南方和北方地区的农民工与来自广东及其邻省的农民工相比，其收入进入到中高收入组的可能性要高出10%。中国社会网络的生态正在由传统的“整合型”社会向现代的“跨越型”社会转变，两种社会形态对农民工经济地位的提升具有互补性，但后者具有更大作用。 |
| Abstract | This paper emphasizes on the sample selection bias and the ordered band property of the survey income data from the Pearl River Delta of China and hence applies the ordered model with sample selection to study the determinant factors which affect the rural migrants’ income including the family characteristic, human capital, social capital and some external system variables. Especially we base our analysis on the two kinds of social capital: “bonding” social capital and “bridging” social capital. The results show that both the “bridging” social capital and the “bonding” social capital have significant and positive effects on the migrants’ income, but the former has a larger improvement effect. Within an enterprise the friendly relationship between migrants and local workers can help increase the probability of the migrants’ earning a high and upper middle wage by about 24%; the migrants from the southern and northern have over 10% higher probabilities of earning a high and upper middle income than those from Guangdong and its adjacent provinces. The modes of the Chinese social net are transferring from the traditional “bonding” to the modern “bridging”. The two modes have complementary effects in improving the migrants’ income level, but the “bridging” social capital now is playing a more important role in this process. |
