| Urban rail transit not only alleviates traffic congestion caused by increasing population,but also brings obvious value increment to land along the line.However,the current rail transit construction depends too much on government finance,resulting in the urban rail transit can not be benign and sustainable development.It is helpful to internalize the external benefit of rail transit to study the premium effect of rail transit on surrounding housing and discuss the reasonable and effective premium recovery mode.Based on this,this paper analyzes the law of rail transit premium on surrounding housing in different markets,and explores the optimization strategy of land premium recovery adapted to China’s national conditions by analyzing the advantages and disadvantages of China’s existing land premium recovery mode.Firstly,this paper analyzes the land premium mechanism of rail transit theoretically,and then compares and selects the models,using the hedonic price model(HPM)for empirical analysis.This paper,taking wuhan rail transit line 8 and line 21 as the research objects,its throughout central urban area in wuhan and far urban area respectively,on the basis of the theory of equal accessibility to measure the influence of the site,and determine the scope of the samples,in the range of residential samples as the research objects,explore different regional differences on the impact of rail transit on housing prices.The results show that :(1)There are differences in the impact range of different rail transit on housing prices in surrounding areas.The influence range of line 8 stations is 0.14-2.42 km,and that of Line 21 stations is 0.18-3.74 km.The radiation range of rail transit in the central urban area is significantly smaller than that in the far urban area.(2)Rail transit has a significant spatial gradient on surrounding housing prices.The housing price around rail transit line 8increases first and then decreases from inside to outside,presenting an inverted "U" shape.The housing price in the 500-1000 m circle has the largest premium range,reaching 28.1%.After 1000 m,the housing price decreases with the increase of the distance from the station.Rail transit Line 21 has the most significant positive impact on housing prices within 500-1000 m and 1000-1500 m circles,with the premium range of housing being 30.9% and 30%,respectively.After 1500 m away from the station,the impact decreases layer by layer.(3)Rail transit transfer stations have a significant effect on housing price.The average price of residential houses around transfer stations of Rail transit Line 8 is 5.9% higher than that of non-transfer stations.Rail transit Line 21 does not have a significant impact on housing prices due to the small number of transfer stations.(4)Rail transit has a segmentation effect on housing price.According to the research results,there are differences in the increase rates of housing prices in different spaces caused by rail transit,and the premium rates of housing prices in all circles around rail transit in the far urban areas are higher than those in the central urban areas.Based on empirical research,this paper further discusses the applicability of land reserve mode and TOD mode in China,analyzes the advantages and limitations of land reserve mode,and explores the concrete implementation of TOD mode in Wuhan city through the case of metro town.Combined with the above quantitative research results,this paper puts forward planning suggestions for the comprehensive development and premium recovery of the surrounding land of Wuhan metro town from the perspective of TOD in terms of circle division,functional positioning and mixed-use.In practical operation,the above two modes can be combined to form a linkage mechanism.During the planning period of rail transit,the land along the line can be reserved preferently,and the surrounding areas of rail transit stations can be fully developed to manifest the land value,so as to better recover the land premium. |
