Research on the Spatial Spillover Effect of Transportation Infrastructure on Total Factor Productivity

Based on the panel data of 29 regions in China from 2001 to 2016, this paper used the spatial econometric model to empirically analyze the spatial spillover effects of railways, highways and general grade roads on total factor productivity. The research results show that during the study period, there is a significant spatial agglomeration phenomenon in China, both in terms of total factor productivity and various types of transportation infrastructure construction; all kinds of transportation infrastructure have promoted the improvement of total factor productivity in the region. The effect is mainly due to the spillover effect of other regions on the region, and the effect of the general grade road is the most significant, followed by the highway, the effect of railway is relatively small.
