Abstract: The subsidy and investment from the central finance in agricultural machinery purchase has been increased year by year. Its implementation scope covers basically all the agricultural and pastoral banners and counties（farms） in Inner Mongolia Autonomous Region. The subsidy scope is further optimized and the subsidy target is relaxed and explicit moderately. The agricultural purchase subsidy policy has achieved good results of ensuring the food production safety and benefiting farmers and herdsmen directly. In view of the present situation in Inner Mongolia, this study investigates the support key points and policy creation of Inner Mongolia agricultural machinery purchase subsidy in the new period and puts forward some suggestions for the policy making.
