| The development of urban land market has been constantly improved.As the external expression of urban land resource endowment information,land price presents different characteristics in different cities due to the imbalance of regional development and the difference of cities themselves.As an important part of urban land price management in China,the formulation and updating of urban reference land price reflect the economic benefits of land use in different periods.It plays an irreplaceable role in the transfer and transfer of land use rights,collection of taxes and fees,regulation and guidance of economic and industrial policies.At present,with the expansion of research scope and refinement of land use,different cities and towns have differences in the selection of evaluation methods and evaluation index system construction of urban reference land price.At the same time,the relevant factors affecting the balance of urban reference land price have not been paid attention to.A unified and comparable urban reference land price system has not yet been formed.The uncoordinated standard land price of cities and towns directly affects the rational allocation of regional land resources and the balanced development of economic society.This paper takes Changchun-Jilin-Tumen Pilot Zone as the research scope,selects urban reference land price of commercial service,residential and industrial urban land in23 counties(cities,districts)in the research area.Explore the spatial distribution structure and agglomeration of land price between cities and towns,understand the differentiation characteristics of land price of different types of urban land,and master the differences of urban land price level within the region.Through the construction of urban land quality comprehensive evaluation index system,using principal component analysis,quantitative analysis of different types of urban land quality differences in urban land quality,judge the quality of all types of urban land quality and the degree of interaction.The regression analysis model was established with the evaluation result of urban land quality as the independent variable and the urban benchmark land price as the dependent variable.The equilibrium equation with better fitting degree is selected to adjust the urban standard land price in the study area to make it more suitable for the actual development level.The results show that:(1)The difference of base land price for residential land is large,followed by industrial land price and commercial land price is relatively small.In the study area,the base price of commercial service land,residential land and industrial land all have the characteristics of first-order weak spatial autocorrelation,and the spatial agglomeration of the base price of industrial land is worse than that of commercial service land and residential land.(2)Urban scale,input-output benefits,road traffic conditions and infrastructure conditions have an impact on urban land quality.All kinds of urban land quality in the research area show the agglomeration characteristics centered on Changchun city,and the quality level of urban land in the periphery is obviously lower than that in the southwest region.In addition,Chaoyang,Changyi and Shuangyang are more attractive to the surrounding towns for commercial and residential land,and the green park has an obvious effect on the surrounding towns for industrial land.The commercial and service land potential of each town is small,residential slightly larger,industrial largest.(3)The quadratic equation has the best effect on the balance of commercial service base land price,and the index model is the best fit for the residential and industrial land base land price,and the judgment coefficient R2 is that residential is larger than commercial and industrial.Nanguan all kinds of land market has the risk of overheated development,Jiutai all kinds of land market has the risk of cold development,so we can put forward the corresponding adjustment suggestions. |
