An important component in urban geosimulation models based on cellular automata is the local spatial interaction between neighborhood land-use types.Spatial interaction between the location of facilities,residential areas and industries has been given more attention in some literatures.Neighborhood interactions are often addressed as the main factors which decide urban dynamics as other factors like natural constraints and institutional controls (land-use policies) are comparatively stable in certain period.However,understanding and calibration of neighborhood interaction for urban geosimulation model is complex due to the many interaction coefficients that do not necessarily yield unique solutions: different processes (rule sets) may lead to identical patterns.Objective of this research is to compare neighborhood interaction of urban land-use change among three metropolitan areas of Tokyo,Nagoya,and Osaka by utilizing the neighborhood interaction model which was proposed for understanding urban dynamics by the authors in 2006.The research aims at to understand the difference of neighborhood interaction of urban dynamics among different areas so as to provide empirical analysis for constructing urban geosimulation models.The results show that although neighborhood interaction is a little different for every active land-use type,the interactions shows similar structure characteristics for one land-use type in the three metropolitan areas.The regressed neighborhood interactions maybe represent the general characteristics of neighborhood effect on urban dynamics of Japan.
