Abstract:

The purpose of this paper is to explore the relationship and interactions between quantity change of cultivated land and economic growth, and to ease the conflicts between cultivated land protection and economic growth. Methods of cointegration analysis and granger causality test were used.The empirical research shows that there were long equilibrium relationships between cultivated land quantity and economic growth at different economic growth periods.Since 1952,the changes of economic growth and cultivated land experienced three periods.The relationship of economic growth and cultivated land quantity reflected mutual causality from 1952 to 1978.Agriculture played an important role in the national economy at this phase.Economic growth was the cause of the reduction of cultivated land quantity from 1978 to 1992.In this period,the amount of cultivated land conversion conformed to the requirements of economic growth.Economic growth was supported by the input of cultivated land from 1992 to 2008.This resulted in inefficient use of land and other issues.Paying more attention to the equilibrium relationships between cultivated land quantity and economic growth at every different economic growth times,finding their change law, grasping the tendency of causal relationship,and rearranging the policy of land management were all used to adapt to the change of economic growth.In summary,easing the conflicts between cultivated land protection and economic growth is an urgent problem to settle.〖
