[Objective] According to the input redundancy and output shortfall, we aimed to design a reasonable land use low carbon optimization scheme, in order to promote low carbon development of industries.[Methods] Based on data envelopment analysis(DEA) method, the input-output index which are based on the latest classified trades of industry construction land control indicators of Jiangsu Province was established, to analyze the land use carbon emission efficiency from 26 industries in 13 city in Jiangsu Province. The comprehensive efficiency, the pure technical efficiency and the scale efficiency was investigated, and the low carbon optimization schemes were proposed.[Results] The comprehensive efficiency of land use carbon emission from 26 industries was generally low, which was the highest in the middle area while lowest in the south area of Jiangsu Province. The highest comprehensive efficiency of carbon emission was the capital and technology intensive industry land.[Conclusion] The land supply policy can be used in government macroeconomic regulation and control to guide the development of low carbon industry.
