The locational structure effects on spatial interaction in distance-decay models have been discussed since the 1970 s. This discussion has led many geographers to obtaine distance-decay parameters affected not by spatial autocorrelation but by friction of distance. As Bennett et al. (1985) stressed, however, we should recognize that spatial structure and spatial interaction are interdependently related. Thus, the present study explores spatial interaction effects on spatial structure. First, using the SIMODEL developed by Williams and Fotheringham (1984), a distance-decay parameter was estimated for intra-urban trips travelled by pensioners to day centres in Malmo, Sweden. in addition, location patterns of those day centres and spatial autocorrelation between them were identified by the nearest neighbour measure and Moran's coefficient, respectively. Second, through solving a location-spatial interaction model, effects of spatial interaction on spatial structure were examined in three cases of distance-decay parameter. It was proven that the three cases of distance-decay parameter caused different location patterns. Combined with previous studies addressed to the spatial structure effects on spatial interaction, the interdependency between spatial interaction and spatial structure was explicated.
