Spatial Spillover Effects of Highway Transport Infrastructure on Economic Growth in Northwest China

摘要

The possibility of spatial spillover effects of transport infrastructure on economic growth was examined in Northwest China, which is analyzed based on spatial spillover theory and Cobb - Douglas production function, using panel data from 1990～2012. The results show that: (1) The output coefficient of local road infrastructure on economy in the Northwest is 0.1325, which means that local highway infrastructure plays a significant role in promoting local economic growth. (2) The output coefficient of ecdemic highway infrastructure on local economy is 0.1512, comes to the conclusion that there is a significant positive spillover effect of ecdemic highwayinfrastructure on local economic growth.
