Abstract:: Coupling efficiency can characterize the coupling effect of the ecological agriculture with commodity economy system, the data evelopment(DEA) analysis method was used to measure and evaluate the development trend of the ecological agriculture with commodity economy in Ansai county. The results showed that there was alternative among the input factors of the ecological agriculture with commodity economy in Ansai county from the factor allocation aspect, so attention should be paid to the rational allocation of factor. From the coupling efficiency aspect, the overall efficiency of the ecological agriculture with commodity economy in Ansai county changed a little and the efficiency values of the most years were greater than 0.85, but the technical efficiency showed random fluctuations, the scale efficiency was relatively slow and the minimum value was 0.658 and the returns of scale in most years presented increasing returns to scale. All these showed that individual and small-scale farming systems can not adapt to the need of agriculture development in the context of the new technology and the new policy, that is to say the development of ecological agriculture with commodity economy in Ansai county needs expand scale of operation to improve the scale efficiency and to promote the new technical efficiency at the same time.
