民族地区产业结构变迁对城乡收入差距的影响——来自内蒙古的经验证据

The Influence of Industrial Structure Changes on the Income Gap between Urban and Rural Areas in Ethnic Regions——Empirical Evidences from Inner Mongolia

在产业结构优化进程中缩小城乡收入差距,是民族地区实现包容性经济增长的题中要义。本文在构建VAR模型的基础上,从产业结构合理化和高级化两个纬度,对1978—2017年内蒙古产业结构变迁与城乡收入差距之间的关系进行了Johansen协整、Granger因果关系、脉冲响应和方差分解等实证分析。实证结果显示:内蒙古产业结构变迁与城乡收入差距存在长期均衡关系,产业结构合理化促进了城乡收入差距的收敛,而产业结构高级化却加大了城乡收入的不平等;同时在内蒙古产业结构变迁中,产业结构合理化与产业结构高级化明显脱节,缺乏应有的良性互动。

Reducing the income gap between urban and rural areas in the process of optimizing industrial structure is an important goal to achieve inclusive economic growth in ethnic regions.On the basis of constructing VAR Mode,this paper makes an empirical analysis of the relationship between the changes of industrial structure and the urban-rural income gap in Inner Mongolia from 1978 to 2017,including Johansen cointegration,Granger causality,impulse responses,and variance decompositions.The results show that there is a long-term equilibrium relationship between the two,and industrial structure rationalization has reduced the urban-rural income gap,while industrial structure advancement has increased the gap.At the same time,in changing industrial structure in Inner Mongolia,there is an obvious disconnection and a lack of proper interaction between industrial structure rationalization and advancement.
