Spatial autocorrelation is an important spatial statistical method in Geographic Information Systems, which can reveal spatial structures and patterns of regional variables. With this method, this article calculates the population density's spatial correlation model for county-level units in Jiangsu province of China in 2001, 2002, 2003 and 2004, explores and demonstrates every county-level's global...
By employing Moran's I and Gini coefficient as measures of spatial concentration, we explore the spatial patterns of interprovincial migration sharing the same origin or destination in China, 1995–2000. The values of Moran's I and Gini for out-migration streams of each province as an origin and in-migration streams of each province as a destination are estimated accordingly. Through comparing these...
