农村公路基础设施对农民收入的影响——基于江苏省2000—2014年县域面板数据的实证研究

An empirical study on the influence of rural highway infrastructure on farmer's income

发达的公路网络不仅可以降低农产品的流通成本与生产成本,扩大农产品的市场范围,提高农业劳动生产率,还可以推进地区的工业化与城市化进程,促进非农产业发展,增加农民的收入。基于对江苏省2000—2014年县域面板数据的回归分析发现,等级公路基础设施对农民的收入有显著的正向影响,其收入弹性系数在0.217~0.225之间,而等外公路基础设施对农民收入的影响不显著。公路基础设施是农村经济社会发展的重要公共基础设施,在总量上仍要进一步加大投资,特别是加强等级公路以及欠发达地区的公路基础设施建设。

The developed highway network can not only reduce the cost of circulation and production of agricultural prod- ucts, expand market scope, improve agricultural productivity, but also boost the industrialization and urbanization, pro- mote the development of non-agricultural industries and increase farmers＂ income. Based on regression analysis on panel data of Jiangsu county area during 2000--2014, it reveals that standard highway infrastructure has a significantly positive influence on farmers＂ income with elasticity coefficient of 0. 217--0. 225, while the influence of unsubstandard highway in- frastructure to farmers＇ income is not significant. The highway infrastructure is important for rural economic and social de- velopment, which requires further increase in investment, especially the standard highway and highway infrastructure construction in underdeveloped areas.
