摘要
Since the western development, pastoral agriculture production of China has made considerable progress. Based on the C2R model and super-efficiency DEA model in this paper, the time variance and provincial diversity of the China＊s pastoral areas and agricultural production efficiency among provinces from 2000 to 2008 were investigated empirically. The results indicated that: (1)since the western development, the efficiency of agricultural production in both nation＊s pastoral areas and all provincial pastoral areas had grown evidently, except that in Tibet autonomous region; (2)according to the efficiency decomposition, the variance in efficiency of agricultural productivity was mainly caused by technical efficiency. And the improvements of scale efficiency are relatively limited; (3) according to the spatial structure distribution of time changes, the differences of efficiency of agricultural production in each province were very obvious.
