Study On The Spatial Effect Of Urban Housing Price In The Southern Section Of The Grand Canal Economic Belt

The Grand Canal is a manually-routed navigation channel that communicates water transportati'on between regions or waters,thereby driving social exchanges and economic development.The Beijing-Hangzhou Grand Canal begins in Hangzhou and ends in Beijing.The Beijing-Hangzhou Grand Canal is not only an important channel for ancient China's external relations,but also has a profound cultural heritage.It is also an important channel connecting the"Beijing-Tianj in-Hebei" business district and the Yangtze River Delta urban agglomeration,and is a meaningful location for regional coordinated development.With the proposal of "building a cultural economic belt of the canal",the national government gradually strengthened the planning of the cultural belt of the canal after conducting a series of investigations on cities along the canal.However,the current economic correlation between cities in the canal economic zone is still unclear,which has brought certain obstacles to the decision-making of the construction of the canal cultural economic belt Analysis of the characteristics of housing prices in major cities along the canal,exploring the spatial linkages of housing prices in various cities plays a vital role in promoting the coordinated development of the Grand Canal regional economy.The Grand Canal Economic Belt involves many sections of the canal.The economic relevance of the cities along the canal is also uneven due to distance and navigation capacity.Therefore,this dissertation focuses on the administrative areas along the Jiangnan Canal with strong shipping capacity.This dissertation selects eight cities along the Yangtze River Canal,namely Nanjing,Zhenjiang,Changzhou,Wuxi,Suzhou,Jiaxing,Huzhou and Hangzhou,to analyze the spatial correlation characteristics of regional housing prices,including three aspects:(1)This dissertation first establishes a modified gravity model to measure the strength of house price linkage between cities.By comparing the strength of the connection,it is found that Suzhou is the price linkage center in the cities along the Jiangnan Canal;the average economic intensity of each city to the target city As the threshold of urban interaction,the intensity of house price linkage between cities is transformed into an asymmetrical 0-1 relationship matrix,which proves that Suzhou is the center of price linkage in the study area.Substituting the 0-1 relational matrix into UCINET software,from the perspective of social network analysis,portrays the associated network of each city's rooms.The results show that Suzhou gradually replaced Hangzhou as the price linkage center along the Jiangnan Canal,and there is a spatial correlation between housing prices in various cities.(2)Secondly,according to the theory of breaking point,the formula of the modified breaking point is established to calculate the radiation breaking point of the house price in each city.Calculate the field strength at the breaking point according to the field strength formula,and select the field strength with the field strength average at each breaking point as the strong radiation radius,and select the field strength with the minimum breaking point field strength as the weak radiation radius,so as to calculate the strong cities.,weak radiation radius.The results show that the eight cities along the Jiangnan Canal have formed a three-core structure with Nanjing,Hangzhou and Suzhou as the core.The radiation range covers the cities along the Jiangnan Canal.Suzhou has the strongest radiation capacity,and its radiation range basically covers the middle section of the Jiangnan Canal.(3)Finally,a VAR(Vector Autoregressive)model is established by taking the monthly price of residential commercial housing in each city as a variable.Through the decomposition of variance,it is found that there is always a significant mutual contribution rate among the three cities in Hangzhou,Nanjing and Suzhou.The price of each city has a significant contribution rate to the first period,and the "cumulative effect" of housing prices is common.Phenomenon;the principle of "declining geographical distance" or the principle of "declining economic distance" does not apply to all urban price conduction pathways,The research in this dissertation comprehensively uses a variety of regional economic models to reveal the current urban house price correlation law along the Jiangnan Canal,and constructs a spatial impact effect analysis model,which clarifies the effect of housing price space along the Yangtze River Canal and expands the traditional regional economics.The scope of theoretical application can be used as a reference for the development planning of the Grand Canal Economic Belt,and it has certain reference significance for the study of the canal economic belt.
