2004. This paper proposes a theory of city size distribution via a hierarchy approach rather than the popular random growth process. Christaller’s Central Place Theoryi Summary: p.406 The main aim of central place theory is to explain the spatial organization of settlements and hinterlands, in particular their relative location and size. REFERENCES De Keermaecker, Marie Laurence, Frankhauser Pierre, Thomas Isabelle. Central place theory includes a number of assumptions and key concepts such as range and threshold, which are used to generate alternative hierarchical distributions of central places, including the marketing (k = 3), transport (k = 4), and administrative (k = 7) principles. Central places generally supply more than one kind of commodity. Central place theory eventhough not entirely adaptable because of some constrains still can be used to select the correct location of central places and market area to gain more profit and urban stability to develop more in the near future. The Rank-Size Rule •If all cities in a country are placed in order from the largest to the smallest, each one will have a population half the size of the city before it. The theory as propounded by Christaller, no doubt, […] ADVERTISEMENTS: Significance and Applicability of Central Place Theory of Christaller! So it is the most effective system in terms of marketing. The Three Principles in the It is possible to find a review of the early work in the Central Place theory and its applications in studies of Berry and Garrison, 1958, Berry and Pred, 1961 and in the books by Bunge, 1962, Lloyd Central Place theory began with papers by Brush and Bracey, 1955, and by Berry and Garisson, 1958, which have influenced many later empirical studies. Central Place Theory . Walter Chistaller’s Central Place Theory assists in beginning the dialogue of expansion and relocation, specifically in relation to market size and a city’s particular ability to support a professional team. VII. They can be divided to higher order center and lower order center which provide different kinds of functions. –Rank 1 – Largest City –Rank 2 – ½ the number of people as Rank 1 city Retail distribution would also take place within the regional city and the satellite cities. Christaller’s Theory makes the following simplifying assumptions: The central-place system of Christaller is applicable partially even to this day in countries of the developing world including India, China and areas where primary occupations predominate. The above diagram distorted the spatial pattern of Christaller's central place theory in order to make the pattern easier to discern. It is the minimum number of central places to serve the given area. Central Place Theory •The central place is located at the vertexes of equilateral triangles that form into hexagons –Displays assumption customers will go to closest place –No overlapping of market influence, and no one left out of influence . Central place theory includes a number of assumptions and key concepts such as range and threshold, which are used to generate alternative hierarchical distributions of central places, including the marketing (k = 3), transport (k = 4), and administrative (k = 7) principles. Chistaller’s spatial theory originated within the field of urban geography and central place theory (CPT) (1933) and Huff‟s law of shopper attraction (1962, 1964). But, these approaches are based on certain assumptions about consumers that are not reasonable now. The theory, it is again emphasized, is normative in character. Likewise the regional city would also have wholesalers which supply its retail distributors. Analysis of Assumptions of Central place Theory (CPT) and Gravity models: There is a similarity between Christaller‟s central place theory, Reilly‟s
