Abstract: A balanced panel of 15 counties (cities and districts) from 1996 to 2012 and a NC-DEA window approach were used to measure the efficiency of cultivated land use in Changzhutan area. The results showed that the economic efficiency of cultivated land use was relatively stable, and it was higher in central cities (cities and districts) than that in suburban areas, which indicated that the external environmental factors had a significant impact on economic efficiency, the favorable social and economic conditions were conductive to the improvement of the efficiency of cultivated land, NC-DEA window approach could evaluate the efficiency of single factor without deleting other factors, a combination DEA window approach of specific factors could provide a significant tool to evaluate land efficiency of other soil types.
