| Nanning is the capital city of guangxi zhuang autonomous region,since I became a permanent site of china-asean expo of nanning,nanning in the beibu gulf economic zone and even the national status is rising,China in recent years(guangxi)free trade area was officially,marks the comprehensive strength of a comprehensive upgrade of nanning,which attract a large number of floating population to come here to study,live,work,With the rapid influx of population,the demand for housing is increasing,which stimulates the rapid development of the real estate industry.The healthy development of the real estate market and the land market is related to the social stability and security.Therefore,this paper analyzes the development status of the land market in Nanning by studying the residential land price in the central city of Nanning.This paper sorts out the relevant literature on residential land price research at home and abroad,and accumulates a certain theoretical basis for subsequent research by learning relevant research results.And other technical means and use the Python creeper crawled took China's urban residential land price dynamic monitoring system of nanning residential land price level and residence of the benchmark land price and housing guest nanning district latitude and longitude,average house prices and a variety of types of POI,road drainage and terrain data,such as the above data after pretreatment by import of nanning residential land database.Research contents in this paper the main body can be divided into three parts,the first part of the overall level of development of nanning residential land prices for qualitative analysis,the second part is to use a variety of geographical spatial analysis method from the Angle of 2 d and 3 d recognition of nanning residential land spatial structure,the third part is the use of factor analysis and regression analysis of nanning residential land price influence factors were studied.The main conclusions of this paper are as follows:From the perspective of the overall development level of residential land price in Nanning City:(1)The residential land price level in Nanning City can be divided into low growth stage and high growth stage:In the low-speed growth stage(from the first quarter of 2010 to the fourth quarter of 2015),the residential land price level in Nanning maintained a low level of growth of about 2000 yuan /m~2,which was about0.4 times of the national residential land price level.In the stage of rapid growth(from the first quarter of 2016 to the third quarter of 2019),the residential land price level of Nanning City maintained a high level of growth of 5000 ? 7000 yuan /m~2,which was about 0.92 times of the national residential land price level.(2)The month-on-month growth rate of residential land price in Nanning can be divided into high-speed growth stage,sluggish growth stage and stable growth stage:During the period of high growth(from the first quarter of 2010 to the fourth quarter of 2010),the growth rate of residential land price in Nanning showed a rapid growth trend.The growth rate of residential land price in Nanning exceeded the growth rate of national residential land price for the first time in this decade.In the period of low growth(from the first quarter of 2011 to the third quarter of 2012),the sequential growth rate of residential land price in Nanning showed a trend of decreasing first and then increasing,and the residential land price in Nanning showed a negative growth for the first time after2010.In the stage of steady growth(from the fourth quarter of 2012 to the third quarter of 2019),the quarter-on-quarter growth rate of residential land price in Nanning maintained a positive growth trend in the fluctuation,and the quarter-on-quarter growth rate of residential land price in Nanning was consistent with the growth trend of the quarter-on-quarter growth rate of the national residential land price.From the perspective of spatial structure of residential land price in Nanning,multiple research methods are superposed to identify four high-value residential land price cluster centers,namely,ASEAN Business District cluster,Jinhu Plaza cluster,Nanhu Park cluster and Dream Island Outlets Plaza cluster.(1)using exploratory spatial data analysis(ESDA)"trend analysis" tools to build nanning residential land price of sample 3 d perspective,nanning residential land prices sample on things,north and south two projective planes are in "n" type distribution,said nanning residential land value sample mainly gather around in the city centre,residential land and decreasing to the suburbs.(2)The spatial autocorrelation analysis of residential land price samples in Nanning shows that residential land price in Nanning has obvious spatial clustering phenomenon.Residential land price in Nanning has obvious local agglomeration phenomenon of high value(H-H)and low value(L-L).High value(H-H)of residential land price mainly concentrates in Chaoyang Square and the east area.The low residential land value(L-L)is mainly distributed in the suburbs of Nanning in the form of semi-surrounded.(3)of nanning residential land price according to the inverse distance weighted interpolation,ordinary kriging interpolation method,analysis method,the natural spline function interpolation neighborhood interpolation method for interpolation analysis,interpolation analysis to identify business district is located in the asean group,golden plaza group,dream island outlet square group three residential land prices high value cluster center.(4)Through the construction of digital residential land price model,identify the high value residential land price cluster center in Nanhu Park.In terms of the influencing factors of residential land price in Nanning,different factors have different spatial attraction effects on residential land price samples,and have different correlations with residential land price in Nanning.(1)The spatial attraction effect of administrative factors on residential land price sample sites is weak.12.52% of the residential land price sample sites in Nanning are collected in the buffer zone of 1000 meters within the administrative center.The standardization coefficient of the distance between the residential land price sample sites and the administrative center is-0.131 in the regression model of residential land price in Nanning,showing a negative correlation between administrative factors and residential land price level.(2)Education has a strong spatial attraction effect on residential land price samples.92.32% of residential land price samples in Nanning are collected in the buffer zone of 1000 meters from primary and secondary schools.The standardized coefficient of the distance between residential land price samples and primary schools in the regression model of residential land price in Nanning is0.065.In the regression model of residential land price in Nanning,the standardization coefficient of the distance between the residential land price sample site and the middle school is 0.122,and the education factor is positively correlated with the level of residential land price.(3)The spatial attraction effect of medical factors on residential land price sample sites is weak.Only 27% of residential land price sample sites in Nanning are collected in the 1000-meter radius buffer zone of third-class A hospitals.The standardized coefficient of distance between residential land price sample sites and third-class A hospitals in the regression model of residential land price in Nanning is-0.217,which is negatively correlated with residential land price level.(4)The spatial attraction effect of environmental factors on the residential land price samples is weak.The 1000-meter radius buffer zone of the park concentrates34.62% of the residential land price samples in Nanning,and the 1000-meter radius buffer zone of Yongjiang concentrates only 25.29% of the residential land price samples in Nanning.In the regression model of residential land price,the standardization coefficient of the distance between the residential land price sample points and the park is-0.207,and the standardization coefficient of the distance between the residential land price sample points and Yongjiang is-0.102.The environmental factors are negatively correlated with the level of residential land price.(5)Commercial factors have a strong spatial attraction effect on residential land price samples.Commercial squares and chain supermarkets collect 70.17% of residential land price samples in Nanning,and the distance between residential land price samples and commercial squares is-0.098 in the regression model of residential land price in Nanning.In the regression model of residential land price in Nanning,the standardization coefficient of the distance between sample sites and supermarket chains is-0.136.Commercial squares and supermarket chains do not have strong spatial attraction ability to high-value residential land samples.(6)The spatial attraction effect of traffic factors on residential land price samples is strong.The1000-meter radius buffer zone of traffic lines gathers 99.20% of residential land price samples in Nanning,and the 1000-meter radius buffer zone of subway stations gathers53.27% of residential land price samples in Nanning.In the regression model of residential land price in Nanning,the standardization coefficient of the distance between the sample points and the expressway is-0.029,and the standardization coefficient of the distance between the sample points and the subway station is-0.258.Expressways and subway stations are negatively correlated with the level of residential land price.In the regression model of residential land price in Nanning,the standardization coefficient of the distance between the sample points and the main road is 0.046,and the standardization coefficient of the distance between the sample points and the secondary road is 0.019.The main road and the secondary road are positively correlated with the residential land price.(7)Policy factors have a great influence on the spatial distribution of residential land price samples.Land "bidding auction," mechanism and "land use planning policies,priority arrangement land use plan and supports more policies,to support and" four big land policy,real estate limited to borrow the restricted for purchasing policy,public rental housing policy,affordable housing policy,reform of existing homes,school district policies,such as inhibition of nanning city planning earth Zhu Zhai De price unlimited growth,We will ensure the steady development of the land market and guide the rational development of real estate. |
