Abstract:

Based on measuring the degree of economic development and land intensive utilization,the paper explored the interactions between economic development and land intensive utilization by dynamic econometrics.The results showed that both of economic development and land intensive utilization were integrated of order one.There existed equilibrium relationship between them in long term whereas things were different in short term,and the range of short term equilibrium was close to long term equilibrium,which was 5026%.Grange causality test showed that economic development was the grange cause of land intensive utilization,but the opposite grange causality couldn’t be proved by the empirical study.The response of land intensive utilization to economic development impulse was remarkable,and the economic development impulse could explain the change of land intensive utilization to a certain extent of 85%.The response of economic development to land intensive utilization impulse was weak,and the land intensive utilization impulse could explain the change of economic development to a certain extent of only 2%.Therefore,it was necessary to vigorously promote transformation of economic development mode,strengthen supervision and management for land utilization, improve the land intensive utilization，and enhance the support capabilities of land resources for economic development
