Based on model SBM and Malmquist index, this paper studies supply efficiency of Chinese agricultural infrastruc- ture of 2000 -2010 from three aspects of effectiveness of DEA, redundancy of input factors, performance evaluation of Malmquist Index. Results show that supply efficiency of agricultural infrastructure is improved ; at lagging agricultural devel- opment regions, supply efficiency is lower, and percentage of redundancy is higher, while at developed regions, there are higher efficiency and less percentage of redundancy. Agricultural infrastructure supply shows a...
