Luo, S. and Fu, Q., 2020. Spatial effects of traffic infrastructure on income disparity. In: Guido Aldana, P.A. and Kantamaneni, K.

This thesis comprehensively takes the impact of multi-dimensional factors on income disparity into consideration. Based on the empirical test model selection, this thesis establishes a spatial econometric model of traffic infrastructure on income disparity. Based on the provincial panel data of China from 1997 to 2017, the thesis draws the following main conclusions through the empirical test: (1) the income disparity brings about positive spatial spillover effect. The difference in value is higher in the West and lower in the East. With the passage of time, the difference expands year by year and the central part is affected; (2) traffic infrastructure has obvious negative spatial direct and indirect effects, which can effectively curb the expansion of income disparity; (3) among the multi-dimensional factors underlying the local income disparity, opening-up, economic development and fixed asset investment have significant negative spatial direct and indirect effects, as they will slow down the expansion of income disparity. It is suggested that the local government should build more traffic infrastructure, improve economic development, promote greater regional economic cooperation, and narrow the income disparity.
