【摘要】：林业生产效率是关系林业经济发展的重要问题。对林业生产效率进行科学地测算与分析,真实反映林业生产效率的实际状况,以期为提高林业生产效率提供科学依据。以竹林生产为例,基于浙江省安吉县6个行政村110户农户调查数据,应用三阶段数据包络分析(DEA)模型对农户竹林生产效率进行测算与评价分析。结果表明:环境变量中,户主受教育年限、竹林收入比例、家庭从事竹林生产人数、家庭经营竹林地块数对竹林生产效率有显著的负向影响;户主年龄、参与竹林生产技术培训、林权证的获得对竹林生产效率有显著的正向影响。在剔除环境效应和随机误差影响后,样本户竹林生产平均技术效率由0.537下降为0.436,平均纯技术效率由0.602上升至0.803,而平均规模效率则由0.891下降至0.556;竹林生产规模报酬均处于递增阶段。基于上述分析,提出降低竹林地细碎化程度,引导农户合理配置竹林生产投入要素,进一步明晰竹林地产权,加大对农户竹林生产技术培训力度等建议。
[Abstract]:Forestry production efficiency is an important issue related to the development of forestry economy. The scientific calculation and analysis of forestry production efficiency can truly reflect the actual situation of forestry production efficiency. In order to provide scientific basis for improving the efficiency of forestry production, taking bamboo forest production as an example, 110 peasant households in 6 administrative villages in Anji County, Zhejiang Province were investigated. Three stage data Envelopment Analysis (DEAA) model was used to measure and evaluate the production efficiency of bamboo forest. The results showed that: among the environmental variables, the number of years of education of the head of household, the proportion of income of bamboo forest, the number of households engaged in bamboo forest production. The number of plots of bamboo forest in household management had a significant negative effect on the production efficiency of bamboo forest, the age of the head of household, the age of the head of household, and the training of bamboo forest production technology, The obtaining of forest right certificate has a significant positive effect on the production efficiency of bamboo forest. The average technical efficiency of bamboo production decreased from 0.537 to 0.436, the average pure technical efficiency increased from 0.602 to 0.803, and the average scale efficiency decreased from 0.891 to 0.556. Some suggestions were put forward such as reducing the degree of fragmentation of bamboo forest, guiding farmers to allocate the factors of bamboo forest production input reasonably, further clarifying the property right of bamboo forest land, and increasing the training intensity of bamboo forest production technology for farmers.
