Previously, we have got some research results in order to explain how retailersagglomerate in a city. We compared two simulation results, one condition in a uniformdistribution of population, the other radially populated so that we investigated howpopulation distribution affects the spatial structure of retailers’ accumulation in a city(2003). These simulation models and other existing studies did not use theattractiveness of shopping streets (areas) effectively in consumer choice because theattractiveness of them includes many elements. Of course although some methods suchas Drezner and Drezner (1998) consider the attractiveness of shopping streets (areas),these models did not explain dynamically change under time series. We have beendeveloping our research continuously, but in this presentation we show a new point ofview relevant to the attractiveness of shopping streets (areas) using SD models. Here weshow our new approach and basic model on shopping street or shopping district inJapan. They are dynamic models of agglomerate retailers, shopping district, in whichthe attractiveness is an important element.
