The Spatial Spillover Effect of Transportation Infrastructure Construction on Regional Economic Development in Central Plains Urban Agglomeration
By using the spatial Durbin model and the mediating effect model,this paper conducts an empirical a-nalysis of the spatial spillover effect and its mechanism of transport infrastructure on regional economic development.The results show that construction of high-speed transportation networks in the Central Plains urban agglomeration has a significant spatial spillover effect on regional economic development,but the impact of different types of highway networks on regional economic development is quite different:the construction of highways has a significant negative local effect and spatial spillover effect on regional economic development,and the construction of highways increases the distortion of resource allocation,and its market integration effect also has a negative impact on the economic devel-opment of cities in the Central Plains urban agglomeration at the present stage.The construction of high-speed rail-ways has a significant positive local effect and spatial spillover effect on the economic development of the region.The construction of high-speed railways significantly improves the efficiency of labor allocation,promotes knowledge spill-over and improves scientific and technological innovation,and advances the economic development in local and neigh-boring areas.
