中国公路网的小世界特性

It is known that a small-world network is often characterized by high connectivity and clustering, so many real-world networks are small-world networks. The past several years have witnessed a lot of interdisciplinary studies on small-world networks, and many of which focus on aspatial and topology-dominated networks, but many real-world networks are spatial networks.Therefore, it is necessary to take a step further to consider the spatial dimensions of the small-world network model. This paper uses network autocorrelation to research small-world properties on road networks in China. Two transportation networks at the national and intra-city levels are anlalyzed by using Moran’s and Getis-Ord’s ,and it is computed that the correlation lag distances when spatial networks at these two scales possess small-world properties.
