Study On The Spatial And Temporal Variation Of Urban Commodity Residence Price

With the continuous improvement of China's housing market and the propulsion of urbanization process,the real estate industry has gradually developed into one of China'snational economy pillar industry.However,the residential pricescontinued to rise,which has become the hot issues that government,residents and real estate developers concerned about.The commercial residential buildings have obvious regional differences,whose prices have a very close relationship with the regional spatial location,the commercial residential buildings in different locations not only have differences in the price level,but also have different change ranges in each time period,that is,existing a clear spatial and temporal variation phenomenon.This study takes Shanghai Pudong New Area as the research area,from the perspective ofspatial and temporal variation to reveal the spatial and temporal variation rules of the commercial residential building prices,and analyze the reasons for the formation of the rules,as well as purpose the corresponding policy recommendations.Firstly,this paper sums up the experience incommercial residential building price research at home and abroad,and elaborates the forming theory and spatial variability theory of commercial residential building price.Secondly,this paper collects and sorts out a large number of urban housing prices and related information in Shanghai Pudong New Area from 2006 to 2015,and commodities the collected data information in accordance with commodity housing price index table.With the support of GIS,using exploratory spatial data analysis(ESDA)technology and Geoda to analyze the trend and spatial autocorrelation of 311 commercial residential buildings' price in 2006 – 2015.Finally,using Kriging spatial interpolation technology to draw the new commodity housing digital price modelin Pudong New Area from 2006 to 2015,and explore the spatial distribution rules of commercial residential building price in Pudong new area during the ten years.In order tounderstand the variation laws of the commodity housing price more clearly,this paper focuses on the combination of space and time,and divides this decade into two phases,draws the digital price model diagram respectively,overlay analyzes data in two period,as well as from the micro perspective to explore the time and space evolution rule of commodity housing price,and analyze the reasons behind the various phenomena.The research shows: overall look the commercial residential building price in Pudong new area from east to west,the west is higher than the east,the east is higher than the middle;overall look from north to south,the commercial residential buildings in the middle northerly have the highest prices,and the prices slightly down to the north,smooth down to the south.On the whole,the spatial distribution of commercial housing prices is clustering model,and has a strong spatial positive correlation.Most communities showed a strong local spatial positive correlation characteristicsthroughout the 2006-2015 period,the High-High type areas are mainly concentrated in Lujiazui,Yang Jing,Tangqiao and Shibo,and the flowers and trees plate areas,but they were all surrounded by the "Low-High" and "High-Low" county cells,which were close to their respective central areas,showing a certain "core-edge model”;the Huinan plate nearby was a low growth zone;the obvious atypical gathering area did not form.The commodity housing price in Pudong New Area took Lujiazui as the core,and gradient diminished to the surrounding.In addition,Huinan and Lingang New City were the secondary center of Pudong New Area's commercial housing prices;the commercial housing prices in Pudong new area took Lujiazui as the center and expanded from center to the south and northeast.During the study period,the area where the commercial housing prices changed greatly were mainly distributed in Lujiazui,Tangqiao,flowers and trees area and the bluish clouds area,whereas the largest growth rate reached 47616 yuan / ?.The commercial housing price spatial variability in Shanghai Pudong New Area is outstanding,and the plate development imbalance phenomenon is obvious.The main reasons for forming the commercial housing price spatial variability in Shanghai Pudong New Area are: traffic,urban development strategy,land price cost,geographical location,environmental factors,and living support and population factors.So this paper suggests that when government develops urban development strategy,macro-control policies and land supply policy,it needs to decentralize its rights of land approval,auction and approval,and needs to appropriately increase the development efforts of remote areas due to the time and local conditions,to relax the purchase policy restrictions in remote areas,improve the corresponding living support,and balance the regional development in each area.
