The Application Of Spatial Location Analysis Based On PGIS In Retail Stroes

While analysing that population and retail stores location, the study on factors of population is often described from such angles as population distribution , density of population , population ' s center , population 's scale , etc. In retail stores location of analysing , an important one is the population purchasing power as above-mentioned factors, different purchasing power needs different retailing unit's type , quantity and scale . While analysing the relation of population distribution , density of population , population centre of gravity , population 's scale and retail stores location, study more such questions as dependence , consistency ,etc., lack more detailed quantitative analysis.In the beginning part of the thesis, we have introduced the relevant research results of population and retails spatial location, Then, we regard main urban area of Chengdu as and study the area, use the fifth census data of Chengdu and census data of retails of Chengdu of 2001, utilize population geographical information system as main research tool , Wilson's shopping model calculate purchasing power of street, on this basis , it is analysed that the retails selects site, distribution of the purchasing power of retails and the retails serves efficiency, offer the reference suggestion for the fact that the retails chooses the location , improves and manages competence , plan the overall arrangement of retails. Then, we discuss in terms of hunman capital how to improve Wilson' s shopping model. First of all, we recommend age-income to pursue , the concept , model , computing technology of Mincerian rates of return . Then, discuss earning ratio of education at all levels , ctegorised method of Mincerian rates of return , on this basis , improve Wilson'sshopping model . The model after improving has described the relation between income level and education level. Utilizing the model after improving, we can calculate the purchasing power of the street more accurately , more effective analysis retails overall arrangement. Finally, we calculate the purchasing power of the street with the model after improving, and carry on the contrast with the result of calculation in the past. The result indicates , the model after improving has fully reflected the influence to purchasing power of the street of education. The question of the thesis is a subject of involving a lot of disciplines, involve the knowledge in such relevant disciplines as demography , urban geography , human geography , urban planning , urban economics ,etc., The thesis is on the basis of relevant knowledge of comprehensive different disciplines , utilize the abundant data materials, a large number of calculation, has analysed the interreaction between people' s purchasing power and overall arrangement of the retail. Apply the hunman capital domain theory model to economic geography, utilize Mincerian rates of return improve Wilson' s shopping model, offered a new visual angle for studying population and retail stores location.
