Road Transportation Infrastructure Development and Urban-Rural Income Gap:An Analysis from the Perspective of Agglomeration and Diffusion Effects
Since the reform and opening up,China's highway traffic infrastructure has developed greatly,but the distribution of highway traffic infrastructure between urban and rural areas and between regions is unbalanced;at the same time,the disposable income of urban and rural residents has increased significantly.This paper intends to study the direct and spatial spillover influences of highway traffic infrastructure development on the income gap between urban and rural residents from the perspectives of agglomeration and diffusion effects.Based on the panel data of 186 prefecture-level cities in China from 2010 to 2019,this paper mainly constructs a moderation effect model for empirical analysis.The main conclusions are as follows:although the proportion of secondary and tertiary industries and the improvement of urbanization rate have the reverse adjustment effect,the development of highway transportation infrastructure has effectively promoted the reduction of the gap between urban and rural residents'income in China.This paper has policy reference value for promoting the cross-regional integrated development of transportation facilities,speeding up the construction of national unified market and promoting the balanced development of urban and rural areas.
