英文摘要：

Through investigations of land use of 718 factories in Jintan County, Jiangsu Province, this paper analyzes the change trend of land use structure efficiency and scale using comparative productivity and unit output land cost, based on area and output of industrial land, and elicits some countermeasures for industrial structure optimization. First,efficiency of industrial land use is better in Yaotang Town and Zhiqian Town, therefore priority should be given to these two towns in adjustment of industrial land use. Second, n the future development of Jintan County, industries of textile and food should be developed preferentially, and industries of electronics, metallurgy and chemistry should be improved, in order to increase efficiency of industrial land and promote industrial upgrading and transition in Jintan County.
