The paper focuses on the changing economic geographies of the outer city of Copenhagen. The outer city is not a well-defined place but can be understood as a set of processes transforming the urban economic landscape outside the built-up area. Several central and interrelated economic processes transform the outer city. The paper examines the changing industrial dynamics and location spaces within the framework of geographical proximity and relation propinquity in order to examine the social and cultural embeddedness of location. Imaginary spaces of location are the social constructs of the firm (of the interviewee representing
the firm). They are representations of the perception, experience and interpretation of the location of the firm. The imaginary spaces of firms in the outer city are different from those of the firms in the built-up area, and a survey points to the fact that multiple rationalities are important in order to understand industrial location.
