[Objective] By measuring and comparing the cultivated land use efficiency of each county in Hubei Province, this paper aimed to summarize their regional differences in order to explore the optimize space of each DMU(decision making units). [Methods] CCR model and super-efficiency DEA(data envelopment analysis) model were used based on the cultivated land use data of 78 county units of Hubei Province during 1987-2012. [Results]The study found that the redundancy of input factors was common in Hubei Province and the cultivated land use efficiency presented regional differences: (1) 95% of the units presented 0%~87% of fertilizer redundancy. (2) Western mountain area and southeast hilly area in Hubei Province presented 42% and 52% of labor redundancy separately. (3) The above two mentioned areas and the Jianghan plain all presented agricultural machinery redundancy with about 40 percent. [Conclusion] (1) Fertilizer amount should be reduced in almost all counties. (2) Agricultural surplus labor should be appropriately transferred in western mountain area and southeast hilly areas of Hubei Province. (3) Agricultural machinery investment should be adjusted on the basis of the local environments and arable land using needs.
