摘　　要：引入流动劳动力的异质性结构对传统人力资本溢出理论进行拓展,分析城乡人力资本溢出、劳动力流动对城乡收入差距的影响机理,并基于新古典增长模型和卢卡斯内生增长模型构造收入函数,运用SVAR动态方法、VECM长短期因果检验和预测方差分解考察城乡异质型流动人力资本等因素对城乡收入差距变动的影响,结果发现:城乡人力资本流动规模的扩大以及低技能人力资本的流出扩大了收入差距,高技能人力资本的流出缩小了收入差距。由于城乡流动人力资本中低技能型比重偏高、高技能型比重偏低,因此,劳动力流动扩大了城乡收入差距。By introducing the heterogeneity structure of labor flow, the authors expand the tra-ditional human capital spillover theory, and analyze the influence mechanism of urban-rural human capital spillover and labor mobility on urban-rural income gap. Income function is constructed based on the neoclassical growth model and Lucas endogenous growth model, and the influence of urban-rural heterogeneous human capital flow and other influencing factors on urban-rural income gap is investigated by using SVAR dynamic method, long-short term causality test of VECM and variance decomposition. The results show that： urban-rural human capital flow scale and the out- flow of low skilled migration human capital widens the income gap, while the outflow of high skilled human capital narrows the gap. Due to the fact that the proportion of low skilled urban-ru-ral human capital flow is larger than the proportion of high skilled human capital, labor mobility expands the urban-rural income gap.
