Abstract:

Core-periphery concept is discussed in the paper and the invalidity of the simple dichotomy is stressed. This concept is applied to the Polish economic space on the national scale. Changes in the Polish spatial-economic system are analysed during the changes in the political-economic transformation in Poland. Three periods are analysed: (1) the top of the developmental potential of "realistic socialism" in the late 1970s; (2) that of the system's transformation and the development of the basic market mechanisms in the early 1990s; and (3) that of the developed market economy in the early 2000s.

Keywords: Core, sub-core, periphery, semi-periphery, core region, frontier region, depressed region, underdeveloped region, development axis, economic transformation.

Abstract:

It is widely accepted in the literature that urban agglomerations play an important part in the national settlement system. The question, however, arises whether they shoud be considered in terms of a common sub-system within the national settlement system or as comprised within their individual regional settlement systems. Beginning with the morphology of the agglomerations, especially from their observed sectoral develpoment, as following bands of the transportation and communication infrastruc-ture, it was concluded that the development was related to the placement of neighbouring agglomerations. On this basis the conclusion was arrived at that the agglomerations must be strongly interrelated. Further on, a hypothesis was put forward that agglomerations form an integrated sub-system within the national settlement system (Korcelli 1976). A test of whether or not urban agglomerations should be considered in terms of common sub-system ought, however, to be supported by an investigation of whether their inter-relationships are more important than the relation-ships ot each of them with its umiand. The answer to this question would allow us to conclude whether changes in the Polish settlement system aim at the develpoment of a single super-agglomeration, as Leszczycki (1973) maintains, or of a system of urban regions with agglomerations as the centres of some of them, as Dziewoński (1972, 1973) agrues. An analysis of the Polish regional structure indicated that agglomerations are entities of a regional rather than national scale; this permitted the hypothesis that the relationships between individual agglomerations and their regions are stronger thar those between the agglomerations are (Rykiel 1978). To test this hypothesis, vectoral data should be used which would allow the distinguishing of the relationships within the hypothetic sub-system of agglomerations, those between individual agglomerations and their respective regions, and those with the rest of Poland.

Abstract:

The last two decades have brought an intensive development of various demo-graphic models and thereby an increased interest in the data concerning all the demographic phenomena. Simultaneously, one could observe a tendency towards comparative studies on the results obtained in different countries, with different models and on the basis of diverse data. It is on these grounds that there grew a broad research program, carried out within the International Institute for Applied System Analysis (IIASA) under the leadership of A. Rogers and in collaboration with several dozens of scientists from almost twenty countries. The key to the successful implementation of the program was the adoption of the unified methodology, described in Rogers (1975), i.e. the so-called Rogers model, as well as the application of the widely available program packages (Willekens and Rogers 1978). In spite of unified methodology "... comparabi-lity is, however, severly handicapped by the considerable degree of incomparability of the input data, in particular the migration data." (Rees and Willekens 1981, p.73). This incomparability resulted from different ways of data collection (registration data versus census data) and from differences in the periods for which data were collected.The work presented is an effort at performing a comparative analysis of the results obtained by the Rogers model when two types of migratory data are fed into this model. The analysis was conducted for the three following aspects: (1) mobility patterns of population represented by raw data were compared, (2) results of the Rogers model for two data types were compared, (3) the usefulness of the data on these two types for forecasting purposes was assessed. The hypothesis was adopted, according to which the two data types, used to generate — in the projections — spatial distribution and population structure settings, display specific features.It should be emphasized that the main goal of the work presented is the study of the influence exerted by methods of measuring migration, and not of the migratory behaviour patterns. In view of the methodological nature of this work it was decided to limit the number of regions considered, so as to simplify the making of comparisons. Basing on such assumptions the study concentrated on two regions: urban and rural. Projections were produced separately for women and for the whole of the population, with disaggregation into 18 five — year age groups.

Abstract:

In this paper, the historical development of the Katowice region is outlined. The scope of the paper is to evidence how the regional development involved the transition from a border region through a bare-joint region towards an integrated region.
