Industrial location


This study presents a means other than the traditional empirical analysis to study the manufacturing mix of urban areas (Rockford-Loves Park). The statistical technique of two-way analysis of variance was applied to two questions. Do industrial activities differ from area to area within a city, and are the various types of industries distributed differently within these areas? Two-way analysis of variance was used to approach both of these questions simultaneously using three variables» employment, the number of firms, and employment per firm. The statistical analysis was applied in two stages. The first stage addressed itself to manufacturing in general while the final stage was concerned with Rockford-Loves Park's two major industrial groups: Fabricated Metal Products (SIC 34) and Machinery, except Electrical (SIC 35). The results of both analyses provided weak support for the hypothesis that industrial activities in their aggregate characteristics did differ from district to district within the study area. The hypothesis that the distribution of manufacturing inside the areas is different was supported more strongly at both stages. In the case of Rockford-Loves Park, it was shown that as measured by three variables, there was statistically more of an internal difference among the industrial groups than a difference between the industrial districts.
