Abstract:

Exploring the interactions between urban land intensive utilization and urbanization has theoretical and practical significance for scientific formulation guidelines and policies for urban land utilization，accelerating land utilization manner change，and promoting social health and sustainable development.Based on defining the connotation of urban land intensive utilization and urbanization，the paper constructed evaluation index system for urban land intensive utilization and urbanization，then measured the level of urban land intensive utilization and urbanization in Jiangsu province from 1985 to 2008 by improved entropy method and efficacy function method The interactions between urban land intensive utilization and urbanization were explored by econometrics analysis method，such as cointegration test，vector error correction model，impulse response function，variance decomposition and so on.The results showed that the level of urban land intensive utilization gradually increased in Jiangsu Province since 1985，while the level of urbanization gradually increased，especially after 1998，and the comprehensive index for urbanization increased rapidly，showing an accelerated growth trend.Both of urbanization and urban land intensive utilization were integrated of order one.There was equilibrium relationship between urban land intensive utilization and urbanization.The improvement of urbanization would worsen the urban land intensive utilization in the short run.However，the increase of urbanization was propitious to urban land intensive utilization in the long run，and the role of response was more prominent and stable.The response of urban land intensive utilization to urbanization impulse was remarkable, and the urbanization impulse could explain the change of urban land intensive utilization to a certain extent of 58.44%; the response of urbanization to urban land intensive utilization was weak and the urban land intensive utilization impulse could explain the change of urbanization to lower level.Therefore，it was necessary to take longterm measures such as further transformation of economic development mode，promoting the strategic adjustment of economic structure，optimizing the layout of industrial upgrading，orderly promoting urbanization，strengthening supervision and management for land utilization，improving the level of land intensive utilization，and constantly enhancing the support capabilities of land resources for economic and social development
