The theme of this book is the emergence and survival of spatial economic structures. How are economic structures created in an otherwise homogeneous environment? The answer is found through an analysis of economic forces that operate in the two dimensional continuum of space. And here economies of scale are found to be paramount. First, the genesis of economic centers is examined by means of a bifurcation model. This leads to a reexamination of the von Thünen model of city and hinterland. Next, the shape and size of Löschian market areas is studied. At the core of the book is a detailed analysis of Hotelling's migration model. Solutions are given for the steady state. The general theme of order from disorder is taken up in the final chapters of this book. Topics from the economics of location, transportation, and migration are treated in models that try to capture the two-dimensional nature of economic space. The reader is introduced to recent techniques in this field

This thesis describes and analyses how the school sector in sparsely populated municipalities in northern Sweden has developed with emphasis on spatial dimensions and in relation to demographic change and political reforms during the last 20 years. In paper I primary schools were studied in a number of small municipalities in the northern parts of Norway, Sweden, and Finland. The aim of the study was to investigate how the spatial structure of schools has changed, what strategies the municipalities have developed to adapt their schools to changing conditions and what constraints there are to apply the strategies. To answer these questions, semi-structured interviews with municipal representatives were conducted. In paper II, the upper secondary school system was studied. The aim of the paper was to analyse the combined consequences of the school reforms, demographic development and competition on the ability of small municipalities to provide upper secondary schools during the period 1997 to 2015 in the four northernmost counties of Sweden. The study was based on data from the database SIRIS at the Swedish National Agency for Education and has a descriptive approach. The spatial structure of school organizations under study has undergone substantial changes during the recent decades, with closures and mergers among primary schools and an expansion of upper secondary schools. In recent years, the size of the young cohorts have decreased, which overall has led to increasing pressures to close primary schools and has created a detrimental competition between upper secondary schools. The large distances and the already small and declining number of pupils have had major effects on the ability to offer a good range and quality in the supply and availability of education. According to representatives from all the studied municipalities, the ambition is to prioritize the primary schools in the municipal centre and have as few small village schools as possible, taking into consideration quality of education, per capita costs, distances, and how scattered the pupils are within the municipalities. Independent schools and their increasingly larger role have attracted a great deal of attention in media, but this is a change that has mainly occurred in municipalities with large populations and their presence in the studied municipalities is very small both at the primary and upper secondary level.

The article is focused on the spatial structure of modern Moscow and features distinguishing it from the cities of Western Europe and the US. The city has hybrid spatial structure combining elements which emerged on different stages of the city development. In the 14th century two tendencies appeared: the prestige of the city centre and opposition of Western districts as more prestigious to Eastern districts as less prestigious. Crucial spatial characteristics emerged in the Soviet era and up to now they define the image of Moscow. Firstly, it's a peculiar density profile. Population density in post-socialist cities tends to increase as we move further from the city centre while in Western European cities population density is the highest in central districts. Secondly, elementary units of Moscow spatial structure are so called micro-districts (neighbourhoods). The concept of a microdistrict was very popular with Soviet urban planners and widely applied in the residential construction. Another peculiarity of Moscow spatial structure is social heterogeneity of districts and absence of ethnic quarters or ghettos. Furthermore, significant part of the city area is occupied by former industrials zones which are not used anymore and need to be reconstructed. With transition to market economy a number of spatial changes emerged. They were partly related to the large-scale privatization, infill construction and lack of effective urban planning policy. In conclusion the article states the need for the new model of spatial organization which would take into account the specifics of Russian reality.

This paper is a review of the literature of that area of spatial interaction which attempts to accommodate the affects of spatial structure. A brief history of this problem is presented, together with criticisms of suggested alternative solutions. Next, spatial interaction in a Christaller K = 3 hierarchy is outlined and its principal components evaluated. Finally, some tentative conclusions as well as several areas for subsequent research are mentioned.

A spatial-equilibrium model of a local public economy is developed in four settings. Each setting is distinguished by two factors: whether the city is 'open' or 'closed', and the method used to determine the urban fringe. The four settings are contrasted by use of a numerical illustration.

This book describes the progress and prominent theories of regional development research in the past decades, especially in the past decade, discusses the industrial structure, spatial structure, resources, and environment, as well as a series of practical issues, and reveals the general characteristics of spatial structure evolution in the process of regional development. The research on the issues of regional development has become the frontier of relevant disciplines since the 1950s, and much progress has been made in the process of solving practical problems in social and economic development. This book provides an in-depth and systematic demonstration of the "point-axis system" theory of regional exploitation and development as well as the T-shaped structure of China's regional economic action in theory and practice and discusses the impact of location differential rent, restricted accessibility, technological innovation, etc., on regional development theoretically. This book is used as a reference for planning, scientific research, and teaching personnel in territorial expansion, regional economy, human geography, etc
