Przestrzeń aktywności ekonomicznej ludności Łodzi
Streszczenie
Artykuł zawiera szczegółową analizę zróżnicowania przestrzennego aktywności ekonomicznej ludności
Łodzi, przedstawioną na tle rozwoju podmiotów gospodarki narodowej w okresie transformacji.
Scharakteryzowano rozmieszczenie firm oraz ich strukturę przestrzenną według wielkości, form własności i
rodzajów działalności, a także dostępności miejsc pracy. During the transformation period the economic base of the city of Łódź underwent
far-reaching changes. This paper seeks to summarise the research on spatial
diversification of business activity of the Łódź population. The research was focused on
spatial distribution of business establishments and labour engaged, types of business and
forms of ownership, as well as availability of jobs. The primary goal of the study was to
characterise the distribution of the above-mentioned variables, especially the degree of
their diversification. The distribution of particular characteristics of business activity was
presented as of January 2001. Graphically, the spatial structures are represented on maps
using a detailed division of the city area into 215 geodetic units.The above analysis
shows that the 18 characteristics of socio-economic spatial structure of Łódź differ
significantly as to their level of variability, although the variability be geodetic units is
usually very high, which can be considered a typical feature of the analysed structure. It
should be taken into account that high variability indicates weak central tendency of the
distributions in question. It should be also noted that a many of the variables (8)
displayed multi-modal distribution.
None of the socio-economic variables showed low degree of variability, while only
one - share of private sector labour in the total labour - showed moderate variability
(V=27.68%). Only four variables displayed high variability (1. share of labour employed
by sole proprietorship firm in the total private sector labour, 2. Share of trade services
labour in the total non-agricultural labour, 3. Share of manufacturing labour in the total
non-agricultural labour, 4. Number of population per I firm). The other variables were
characterised by very high variability, with four variables displaying variability in excess
of 200%: 1. Number of employed in the public sector, 2. Number of employed in trade
services, 3. Number of employed in non-trade services, 4. Total number of employed. It
can be stated that particularly high degree of variability goes hand-in-hand with very
high skewness and kurtosis. Therefore most of characteristics of this kind may be used in
elaboration of socio-economic spatial typology of Łódź.
