[Objective] To study the relationship between the change of cultivated land and the developments of different industry and provide some references for reasonable use and protection of cultivated land resources

and for promoting regional social and economic sustainable development in Hubei Province.[Methods] Based on the collected data of cultivated land area

primary industry output

secondary industry output and tertiary industry output during 1991 to 2014 in Hubei Province

this paper tested whether there is a long-term stable equilibrium relationship among the above variables using the methods of unit root and co-integration. And by the methods of impulse response function and variance decomposition

this paper further analyzed the relationship between cultivated land area and different industry outputs respectively.[Results] There existed equilibrium relationship between the cultivated land area and each kind of the industry output in the long term in Hubei Province. The impulse response function can be used to analyze the relationship of these variables. The primary industry and the tertiary industry outputs were advantageous to the protection of cultivated land

but with only small contributions to it. The development of secondary industry needs a large consumption of cultivated land resource but in a long run

this kind of pressure can be eased with the gradual adjustment of its structure. According to the result of variance decomposition

the contributions of cultivated land area to the developments of all industry are low

while the secondary industry has an obvious promoting effect on the primary and tertiary industry

meaning that the cultivated land consumed was underused.[Conclusion] Hubei Province needs to promote sustainable development of social economy

to deal well with the relationship between the cultivated land protection and economic development. Issues of improving the efficiencies of land use and economy

modifying industrial structure

and forming a virtuous circle are in urgent need.
