摘要
基于1992-2017年我国29个省区市的面板数据,采用非线性门槛模型系统地分析交通基础设施建设、劳动力流动和城乡收入差距之间的关系。研究结果表明:交通基础设施建设能够有效促进农业劳动力向非农业部门的流动,进而影响城乡收入差距,并且交通基础设施建设对城乡收入差距的影响并非呈现简单的线性相关关系,而是随着农村劳动力转移程度的变化呈现出“U”型的动态相关关系。当农村劳动力转移率低于0.157时,交通基础设施建设能够缩小城乡收入差距;当农村劳动力转移率超过0.288时,交通基础设施建设不利于缩小城乡收入差距,并且随着农村劳动力转移率的进一步提高,交通基础设施建设对城乡收入差距的负面影响会增大。
Based on the panel data of 29 provinces and municipalities in China from 1992 to 2017,this paper systematically analyzes the relationship among transportation infrastructure construction,labor mobility and urban-rural income gap by applying the nonlinear threshold model.The empirical results indicate that transportation infrastructure construction can effectively promote the flow of agricultural labor to non-agricultural sectors,which affects the level of urban-rural income gap.What's more,the impact of transportation infrastructure construction on the urban-rural income gap is not a simple linear correlation,but a U-shaped dynamic relationship with the change in the degree of rural labor transfer.If the transfer rate of rural labor is lower than 0.157,the construction of transportation infrastructure can narrow the urban-rural income gap.If this rate exceeds 0.288,the transportation infrastructure construction is not conducive to narrowing the urban-rural income gap.Moreover,as this rate further rises,the negative impact of transportation infrastructure construction on the urban-rural income gap will be greater.
