| 内容提要 | 本文通过构建一个两部门动态一般均衡模型，分别和综合考察了居民消费结构升级、技术进步、部门间资本租金扭曲和工资扭曲这四个因素对我国农业劳动力转移的影响机制和影响程度。数值计算结果表明，四种因素对农业劳动力转移都有不同程度的正面影响。当四种因素叠加且都变化0.1个单位时，居民消费结构升级对农业劳动力转移的影响程度最大，为4.63%，其次是部门间资本租金扭曲（2.68%）与部门技术进步（2.34%），部门间工资扭曲的影响程度最弱，只有0.84%。前三种因素的影响程度非常显著，表明促成我国农业劳动力大规模转移的主导原因是多因素叠加的，是复合型的，这与美国经济城乡一体化进程中的情形有很大不同。这个发现表明刘易斯模型对中国农业劳动力转移的原因解释是有限的，我国学界流行的“城乡工资差别是农业劳动力流动的主要原因”的观点是有片面性的。 |
| Abstract | This paper constructs a two-sector dynamic general equilibrium model to investigate the mechanism of how each of the following four factors influences China’s rural-to-urban labor migration, i.e., household consumption upgrade, technology progress, sectorial capital rent distortion, and wage distortion. We also explore the relative contribution of each factor in a unified framework. Our steady-state numerical results show that each of the four factors has a positive impact on labor migration to a different extent. When all four factors deviate by 0.1 unit from the initial steady state, household consumption upgrade exhibits the largest impact by promoting 4.63% more labor migration. The capital rent distortion and technology progress come closely with2.68% and 2.34% more migration while wage distortion has the weakest effect with only 0.84% more. This finding implies that the dominant reason for China’s rural-to-urban labor migration is essentially compound, which is significantly different from the United States case with just a single leading cause. Our finding also suggests the limited explanation power of Lewis model that excessively emphasizes the importance of sectorial wage difference across rural and urban areas. |
