Abstract：From the perspective of spatial structure， the promotion of Yangtze River Economic Belt strategy belongs to the remolding process of spatial network structure， and infrastructure construction plays a dominant role in the remolding of spatial network structure. As two kinds of infrastructure， transportation and Internet have different effects on the formation of spatial network structure in the Yangtze River Economic Belt， and they have joint effects on the formation of the overall spatial network structure. Based on the analysis of traffic accessibility， it is found that the whole economic belt presents a high middle and a low upper and lower reaches with obvious spatial differences， forming a radial spatial network structure. The information flow analysis based on Baidu index elucidated that the Yangtze River Economic Belt formed a multi-nuclear space network structure， which has obvious clustering effect. Taking traffic and Internet into consideration， the paper USES gravity model to analyze the spatial network structure of “multi-core and multi-group” in the Yangtze River Economic Belt. The study fully demonstrates that the transportation and Internet have obvious differences in the formation mechanism and effect of the spatial structure of the Yangtze River Economic Belt.
