Study On The Influence Mechanism Of Land Price On The Upgrading Of Industrial Structure From The Perspective Of Coordinated Development Of Urban Agglomerations

Since the 21 st century,urban agglomerations have gradually become an important growth pole of China's economic development.At present,there are some problems in the industrial structure of urban agglomerations,such as insufficient economic driving role of core cities,weak economic capacity of intermediate level cities,convergence of industrial development strategies of small and medium-sized cities.These problems can restrict the industrial structure upgrade of urban agglomerations.As the value judgment standard of urban operation,land price reflects the supply and demand of urban land,land use mode and economic development.Land price mechanism plays a regulatory role in the adjustment of regional overall industrial structure and in the coordinated development of regional industries by acting on industrial agglomeration and industrial transfer.Therefore,this paper studies the impact mechanism of land price on the upgrading of industrial structure from the perspective of coordinated development of urban agglomerations.This paper analyzes the influence mechanism of land price on the upgrading of industrial structure from two aspects: mechanism and economic theory,and then puts forward the research hypothesis of land price on the upgrading of industrial structure.This paper analyzes the current situation of land price and industrial structure in three urban agglomerations,and sums up the existing problems.The panel threshold regression model and spatial Dubin model are used to study the upgrading of industrial structure.We can reach the following conclusions from the research above: First,the rise of land price has a significant role in promoting the industrial structure upgrade of the whole country,Beijing Tianjin Hebei Urban Agglomeration,Yangtze River Delta Urban Agglomeration and Pearl River Delta urban agglomeration,and such promotion is achieved by crowding out the second industry with low added value and clustering the third industry.Second,the land prices of the three urban agglomerations has a significant role in promoting the industrial structure upgrade than the land price of the whole country.Third,the rise of land price has a threshold effect on the industrial structure upgrade,and the threshold values of the whole country and each city group are different.Taking the Pearl River Delta Urban Agglomeration as the empirical object of spatial spillover effect analysis,we find that there are significant positive spatial autocorrelation coefficients between the industrial structure upgrade,and the proportion of the second industry and the proportion of the third industry respectively.The spatial spillover effect of land price on industrial structure is significant among cities in the urban agglomeration.The land price of higher price area has a positive spatial spillover effect on lower price area in aspects of the upgrading coefficient of industrial structure,the proportion of secondary industry and the proportion of tertiary industry.The empirical results are consistent with the theoretical analysis and research hypothesis.Finally,based on the land price mechanism,the paper puts forward the countermeasures and suggestions for the industrial structure upgrade of urban agglomerations.It is suggested to use the gradient land price policy to adjust the development of the second industry and the third industry respectively to achieve the purpose of industrial upgrading.In addition,urban agglomerations at all levels should formulate the land price adjustment policy in line with their own development stage.Finally,strengthen the top-level design within urban agglomerations to form an integrated land price management mechanism and industrial development mechanism system.
