Abstract:

The study portrays the dynamic change process of the transport infrastructure income effect, by constructing a differential dynamic model of the influence that the transport infrastructure has on farmers’ income. Using the data of the rural area in 11 western provinces, the paper demonstrates the existence of the threshold effect and solves the threshold range of different regions and the direction and preconditions of the transport infrastructure income effect. The study concludes that the relationships between the growth rate of rural transport infrastructure and agricultural labor capital and agricultural labor wages are all inverse U-shaped. What is more, a moderate distance and a certain number of employed population are the preconditions for the income effect of transport infrastructure, of which the size and direction vary with the geographical location of each province. Except Chongqing, Sichuan, and Guangxi, the rural transport infrastructure in the western provinces has achieved a threshold value range that the income effects are no longer significant.

摘要:

构建交通基础设施影响农民收入的微分动力学模型,从理论上刻画了交通基础设施收入效应的动态变化过程,并结合西部11省区农村现实数据检验其门槛效应的存在性,求解出不同地区的门槛值区间、作用力方向及前提.研究发现,农村交通基础设施与农业劳均资本和工资等的增长率之间均表现出倒U型关系,其作用大小和方向随着各省区地理位置的差异而发生变化,距离适中且保持一定的就业人口数量是交通基础设施收入效应产生的前提.除重庆、四川和广西外,西部其余省区农村交通基础设施已达到收入效应不再显著的门槛值区间.
