产业结构升级、劳动力流动与城乡收入差距——基于中国30个省级面板数据实证分析

Upgrading of Industrial Structure,Labor Mobility and the Income Gap Between Urban and Rural Areas——An Empirical Analysis Based on the Panel Data of China's 30 Provinces

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。

This paper builds a mathematical model and finds that the industrial structure upgrading will expand the income gap between urban and rural areas while labor mobility can narrow the income gap. Using the 1994-2013 provincial panel data,this empirical study finds that with control over a series of variables,the results support the conclusion of the mathematical model. With a more profound analysis,it is revealed that industrial structure upgrading will expand the income gap between urban and rural areas while the optimization of the industrial structure can narrow it. Labor mobility can also narrow the income gap but has a threshold effect. The study also shows that the income distribution effects of industrial structure upgrading displays certain differences between various regions in China.
