Land conversion is an inevitable phenomenon in the process of economic development . As to the economic development

land conversion is an input factor and however

in different stages of economic development

the factor has different effects on economic development . In order to explain the relationship between the spatial difference of land conversion and the stages of economic development

this paper adopts the change rate of arable land occupation and imbalance index of land conversion. Results show that the rate of farmland conversion is gradually descending

among all land categories and the change rate of arable land occupation in city construction

industry

and mining is the fastest . At the same time

the imbalance of land conversion relative to GDP and non-agricultural sectors is increasing and the imbalance relative to labor of non-agricult ural sectors is decreasing. On the whole

spatial difference of land conversion in J iangsu Province is basically in conformity with the level of economic development .
