To reveal change pattern of fanner's forestry productivity after the reform of the collective forest property rights system and to provide a scientific basis for deepening the reform, this paper analyzed changes in farmer's forestry total factor productivity with DEA-Malmquist index approach and its key influence factors by Tobit regression on the base of surveys of 71 farmer households in Fujian. The analysis showed that the high increase rate of pure technical efficiency led the average annual growth of the forestry total factor productivity, accounting for 7. 4% from 2004 to 2009, but there were big differences in the increase rate between components and individuals. Although the science and technology level, the forest land scale, the fanner method and the management type all could have effects on forestry total factor productivity, technical progress and the change of scale efficiency did not contribute much to growth of forestry total factor productivity due to their little changes after the reform of collective forest property rights system. Therefore, to promote sustained and rapid growth of forestry productivity we should promote the forestry scientific and technological innovation and progress, strengthen the forestry technical training, promote forestland circulation and strengthen farmers' cooperation in forestry operation.%为揭示集体林权制度改革后农户林业生产率变动规律,从微观主体的角度,以福建省71个样本农户为决策单元,应用DEA-Malmquist指数法测算分析林改后农户林业全要素生产率变化情况,用Tobit回归找出关键影响因素.结果表明:2004-2009年间,主要由纯技术效率大幅增长带动的农户林业全要素生产率年均增幅较大,为7.4％,但各分量之间的差异和个体之间的差异很大.虽然科技水平、林地规模、耕作方式和经营类型对林业全要素生产率影响很大,但由于林改以来林业科技进步不大,林地规模偏离适度规模的程度更大,所以技术进步和规模效率变动对林业全要素生产率增长贡献很小.因而,推动林业科技创新和进步、强化林业技术培训、促进林地流转、加强农户林业合作经营是集体林权制度改革配套体系建设、促进林业生产力水平持续快速增长的重点.
