Taking the bidirectional relationship between land finance and urbanization as the breakthrough point,this paper selects data of land finance and urbanization from 2001 to 2014 to calculate the coupling degree of land finance and urbanization of 31 provinces (cities) in mainland China.Based on the methods of combining cluster analysis and qualitative and quantitative analysis,this paper studies the temporal and spatial differences between land finance and urbanization.From the social and economic development,land finance and urbanization level,31 provinces(cities) are divided into four areas:high level of urbanization,low economic and financial dependence on the land (highly coordinate),economic and high level of urbanization,greater reliance on land finance(moderately coordinate),low economy and urbanization level (inadequately coordinate),and large financial dependence on the land economy and urbanization level,financial dependence on the land (low coordination).Therefore,this paper further analyzes the causes of temporal and spatial differences between land finance and urbanization and puts forward the control policy to optimize the relationship between land finance and urbanization on the basis of different regions.
