摘　　要：利用2005年全国1%人口抽样调查的子样本数据以及2012年流动人口动态监测调查数据,研究了各可观测因素对自营者和受雇者收入分布的解释能力存在何种差异,及其在2005—2012年间所发生的变化。考虑到就业方式选择的内生性问题,文章首先采用转换回归模型对自营者和受雇者的收入方程进行了估计。在此基础上,进一步根据基于回归分析的分解分析方法,利用Shapley分解过程对自营者收入的Gini系数和受雇者收入的Gini系数分别进行了分解分析。结果显示,对于流动人口而言,收入分配过程中的制度性障碍正在减少。This paper studied the differences among the power of different observable factors for explaining the income distri- butions of two types of employed individuals and their changes during the period of 2005--2012, using the suhsample data of sampling survey data of 1% population in China in 2005 and the data from monitoring floating population dynamically in 2012. Given the endogeneity in the selection of employment pattern, this paper firstly estimated the earning equations of the self-em- ployed and wage workers using the switching regression model, on the basis of which this paper then decomposed and analyzed the earnings Gini coefficients of the self-employed and the wage-employees using decomposition method based on the switching re- gression model and the Shapley decomposition process. The results show that the institutional barriers in the income distribution process are decreasing for the floating population.
