Research On The Influence Of Land Policy On Urban Land Price Based On PSR Model

As the most basic ecological environment factor for human survival and development,land is also an indispensable and basic part of the modernization of urbanization.For the smooth and continuous promotion of urbanization,from traditional rural society to modern urban society,how to make better use of land and development has become a hot social issue.Influenced by Chinese basic national conditions and land system,this paper in virtue of the characteristics of land supply and demand and structural balance to explore the influence by the land policy to the land price.Based on the practice data accumulated by the government in recent years,on the basis of existing research,this paper focuses on the impact of land policy on land price change and how to control the scale of policy control,The scale of regulation and control will find a new way and direction for promoting the coordinated development of regional economy and stabilizing domestic economic structure.Based on the macroeconomic theory,land rent price theory and regional theory as the theoretical guidance,relying on the National Natural Science Foundation Project "Multi-scale urban land price differentiation regularity study"(No: 41471090,2015-2018),the Hebei Province Natural Science Foundation Project "Regional land price system structure optimization and reasonable domain research"(No: D2015205225,2015-2017)and Hebei Normal University Doctoral Foundation Project "Beijing-Tianjin-Hebei urban land price coordination development: space pattern,the regional difference and influence mechanism"(No: L2016B14,2015-2018),with "pressure-state-response" model as the basic framework,this paper enumerates and classifies the domestic land control policies and summarize the quantifiable indicators of land policies.And screening,combining domestic and foreign relevant research and analysis,finally obtained the evaluation index system of Pressure index,response index and state index,and based on the data obtained from the established model to visually describe the impact of land policy on land price.Taking the quantification of policy as the highlight,enriching the theoretical system of urban land price in China,selecting the data of 11 prefecture-level cities in Hebei Province from 2012 to 2016,comparing the differences in time series and spatial distribution,analyzing and summarizing the distribution law of the relationship between policy and land price in Hebei Province on the basis of the model,the main conclusions are as follows:(1)The involvement and application of the PSR model is a new research idea for quantifying policies and analyzing the evaluation indicators affecting land prices.The PSR model based on the relationship between environment,pressure and current situation symbolizes the interaction among the three.It can be substituted into the impact analysis of land policy and land price,together with various factors and indicators to promote the growth of land price,which constitutes a complete chain relationship.The framework of the impact of land policy on land price is basically formed.The pressure item,state item and response item in the model can quantify the land policy factor,urban attraction factor and land price.The trend map of the three variables is more intuitive.Therefore,on the basis of comprehensive analysis of the land policies over the years,it is feasible to use the PSR model to analyze the macroeconomic regulation and control of land policies,and to influence the influence factors of land price changes and land prices from the natural and human perspectives.(2)Through the empirical study of 11 prefecture-level cities in Hebei Province,we find that from the perspective of time series,it has the following characteristics: the pressure index shows an upward trend in 2012-2015,the land price growth trend slows down,the pressure index shows a downward trend in 2015-2016,and the land price increases;the state index and the response index influence each other,and its trend gradually tends to trend with the development of time.Yes.On the whole,the land price in Hebei province still keeps increasing trend,which is related to the level of economic development of the city.The lower the level of development,the lower the land price burst.When the pressure item and the state item act together on the urban land price,the effect of land policy is greater than the effect trend of the state item on the land price.(3)From the study of the regional differences of land prices in different cities of Hebei Province,it is found that land policy plays a more obvious role in regulating the changes of land prices.Under the circumstance of different orientation of cities and different level of economic development,the emphasis of policy implementation is different,and the growth of regional land price is different.Comparing the increase range of land price in recent years,the ranking from high to low is: Baoding,Handan,Cangzhou,Shijiazhuang,Zhangjiakou,Langfang,Qinhuangdao,Hengshui,Tangshan,Xingtai and Chengde.The change rule of land price growth rate from southwest to northeast is "high-low-high-medium-low".(4)Considering the current situation of Hebei Province,in order to ensure the stable development of land price in the large-scale pattern,it should be adapted to local conditions,combined with the current status of the land market and the data of land stocks,in the policy inhibitory stage should take into account the role of land prices in the economic structure,guarantee the quantitative land to enter the market,so as to avoid the possibility of too low public expectations and economic decline.In the policy encouragement period,we must ensure long-term development.While attracting investment,we will effectively implement the housing policy and vigorously transform housing in shantytowns,and increase the proportion of shanty towns and affordable housing in the annual housing area,closely related to monetary policy and taxation.The combination of policy and real estate policy,actively responding to the requirements of the 19 th National Congress,adhere to the positioning of “households and non-speculation” and play a positive role in policy guidance and regulation.
