摘　　要：利用数据包络分析(DEA)方法,选取代表农业投入和产出的指标体系,以贵州省为研究对象,对其2003-2012年农业投入产出效率进行测度和分析。研究结果表明:(1)近17a间贵州省的农业投入产出综合效率波动变化较小,总体上处在一个接近最优的状态。规模效率是影响贵州省农业投入产出总体效率的主要因素。(2)在规模报酬可变情况下,效率无效年份均出现投入的冗余,在各项冗余指标中农作物播种面积、化肥投入和农药使用出现的冗余量较大。存在过度垦殖,化肥、农药过量使用的现象,通过消减各项投入冗余可使农业的产出效率达到最优状态。分析结果可为下一步贵州省生态环境建设和生态农业的可持续发展提供有益参考。Using data envelopment analysis （DEA） method, selecting input and output indexes, taking Guizhou Province as the research object, to measure and analyze the input-output efficiency of agriculture in 2003-2012. The results show that ： （ 1 ） The volatility change of comprehensive efficiency of agricultural input and output was smaller nearly 17 years in Guizhou province, generally in a nearly optimal state.Scale efficiency was the main factors influencing the overall efficiency of agricultural input and output in Guizhou. （2） In the case of the variable scale re- ward, invalid year of efficiency appeared input redundancy, In the redundant indicators, crop planting area, fertiliz- er input and pesticide use were bigger; There were excessive reclamation, excessive use of fertilizers and pesticides, by cutting the input redundancy can make agricultural production efficiency to achieve the optimal state.The results of the analysis can provide some useful references for ecological environment construction and the sustainable devel- opment of ecological agriculture in Guizhou Province.
