摘　　要：基于三阶段数据包络分析(DEA)模型对福建省三明市856户农户林业单户、联户及股份经营的综合效率、纯技术效率和规模效率进行了评价。结果显示:环境因素对于林业3种经营形式的经营效率有不同程度的影响。其中,农户家庭人均收入、立地条件是提高单户经营效率的有利因素,外出打工人数、财政补贴是提高单户和联户经营效率的不利因素,受教育程度是提高联户和股份经营效率的有利因素,经营技术水平对单户和股份经营效率提高有促进作用。在剔除环境因素影响后,联户经营的经营效率最高,股份经营的次之,单户经营的最低,且均存在投入松弛。因此,应提高3种形式的经营效率,改善投入松弛现象。The efficiency of forestry management is crucial for the development of forestry. This study developed threestage data envelopment analysis（DEA） model was developed for measuring the technical efficiency,pure technical efficiency and scale technical efficiency of different households forest management models. Data were collected and analyzed from 903 households in Sanming City,Fujian Province. The results illustrated that environmental variables had some impact on the efficiency of three management models. Furthermore,family annual per-capital income had a positive effect on the efficiency of individual household. How ever,the number of household work outside and forestry financial subsidies had negative influence on the efficiency of individual household. In additional,the educational level of household was favor to the efficiency of partnership and joint shareholding management. The technological level of household was proved helpful for improving the efficiency of individual household and joint shareholding management. After adjustment of the environmental variables and statistical noise,average technical efficiency of partnership management was the highest among three management models,which joint shareholding management followed and individual household was the lowest. Our findings also showed that the three managements all had input slacks. Therefore,some suggestions should be taken into consideration to improve the efficiency of three management models and decrease the input slacks.
