构建数理模型发现,产业结构升级会扩大城乡收入差距,劳动力流动能缩小城乡收入差距。运用1994—2013年的省级面板数据进行实证检验,研究发现:在控制了一系列变量的条件下,实证结果支持了数理模型的结论。进一步分析还发现,产业结构高级化会扩大城乡收入差距,而产业结构合理化却能改善城乡收入差距;劳动力流动能缩小城乡收入差距且具有门槛效应。研究还表明,产业结构升级的收入分配效应在中国各区域之间存在一定的差异性。
Building a mathematical model found that the upgrading of industrial structure will expand the income gap between urban and rural areas, labor mobility can narrow the income gap between urban and rural areas. Using the provincial panel data from 1994 to 2013 for empirical tests, the study found that the empirical results support the conclusion of the mathematical model under the control of a series of variables. Further analysis also found that the high-level industrial structure will expand the income gap between urban and rural areas, while the rationalization of industrial structure can improve the income gap between urban and rural areas; labor mobility can narrow the income gap between urban and rural areas and have a threshold effect. The study also shows that there is a certain difference in the income distribution effect of the upgrading of industrial structure in various regions of China.
