摘　　要：本文建立了一个基于技能偏向型技术进步的一般均衡模型,表明教育回报率的变化是引起我国劳动者收入不平等扩大的重要原因。基于该模型的进一步推导分解出了教育的要素回报效应与要素结构效应,前者拉大了收入不平等,后者降低了收入不平等,但总效应仍然是收入不平等的扩大。利用基于RIF回归的分解方法,本文验证了上述理论预测与实际数据的高度一致性。This paper establishes a general equilibrium model based on the framework of Skill-Biased Technical Change to illustrate that change in return to education is the main source of rising income inequality in China since early 1990s. The model shows that the total effect of education on income inequality can be decomposed into factor price effect and factor composition effect. While the former widens the magnitude of income inequality, the latter tends to narrow it. However, the total effect is still the rising of inequality. Using newly developed RIF regression techniques, our empirical results indicate that the model＇s predictions are highly consistent with the data.
