Abstract: As two major modes of transportation, aviation and high-speed railway complement each other to form a modern rapid transportation network, which promotes the adjustment of economic pattern and the spillover of regional economy by changing the spatial correlation between cities. The influence of aviation and high-speed railway network on the overall pattern and internal structure of urban spatial correlation is analyzed, and empirically the relationship and difference between urban spatial correlation and economic spilt under the influence of aviation and high-speed railway network is tested, based on the panel data of Chinese cities at the prefecture-level and above, and using G2SLS tool variable estimation and other methods. The results show that the spatial association of cities under the influence of aviation network has obvious leap and rank. Under the influence of high-speed railway network, the urban spatial association has distinct geographical and adjacency attributes. Airlines and high-speed network of urban spatial correlation between the broader, contribution to its economic output, the more obvious, the excessive concentration of aviation network center close to the center of the urban space correlation degree and there is a negative correlation relationship between economic output, but the relationship is not stable in the high-speed network, cities and the high-speed rail network in aviation hub and control of the network capacity has important significance to the economic development. In the future, to strengthen the spatial relationship of Chinese cities and promote the national economic growth, it is necessary to conduct policy coordination in shortening the space and time distance, reducing regional segmentation and increasing network density.
