Article Description

Spillover effect of transport infrastructure is a significant concern to researchers and policy makers, for the improvement of transport infrastructure by the local government in a region will increase the accessibility of the neighbouring regions, which may bring more benefits to the neighbouring regions than to the local region. After the reform of airport localization, the local governments in China are playing more and more important roles in airport investment and management. However, so far in China, there has been little research on the spillover effect of airports. Using the dataset in 2009 and the accessibility measures, this paper examines the spatial spillover effect of civil airports in China. Here the spatial spillovers of accessibility for a given region are defined as the overall increase in accessibility of the neighbouring regions brought by the airports in the given region. Based on the network analysis tools in GIS and the potential model, a methodology is devices to realize the definition. Then we calculate the spillovers of accessibility at province and city scales. Results indicate that the spillover effect of accessibility at the province scale is rather weak. The average ratio of the spillover effect of accessibility at the province scale is only 2.1%. It is much stronger at the city scale and varies significantly. The average ratio of the spillover effect of accessibility at the city scale is 8.1%, and the highest one reaches 55.3%. These results offer very useful information for both planners and policy makers. And particularly, the implications for institution design on the coordination at the city level are also discussed.
