The major conclusions of this study can be summarized as follows : there is a two-way causal link between land use and land values ; within the study area, the effect of freeways on land value changes is minimal ; changes in the relative position of land value categories are related to the location of the main stations of the new subway. It is not surprising, then, to uncover an important « regional » effect. Among social factors, family status, indexed by family size, contributes heavily to the prediction of the intra-urban surface of land values. The model could be ascertained more definitely if the cross-sectional analyses were performed at more distant points in time.
