Abstract

Artykuł prezentuje kompleksową typologię przestrzenną aktywności ekonomicznej ludności Łodzi. Uwzględniono w nim charakterystykę doboru cech diagnostycznych, zastosowanej metody taksonomicznej oraz wydzielonych typów jednostek terytorialnych.

During the period of transition to the market economy the economic activity of Łódź population underwent far-reaching changes. This paper attempts at a comprehensive spatial typology of the economic activity of Łódź population. The typology was based on various variables characterising this activity such as volume and density of employment, size of enterprises, role of different ownership types, structure of non-agricultural employment by sectors (manufacturing, construction, market and non-market services), availability of employment. The main purpose of the research was to identify types of economic activity in the urban space of Łódź and to define their characteristics. The identification of the types of activity was carried out using the MacQueen’s k-means method. It was found that division of geodetic units into 8 types assures best the condition of separateness of clusters. Each type represents a specific combination of standardised average values of diagnostic variables and different spatial distribution (annex 2; fig. I). The names of individual types are derived from their most distinguishing characteristics.
