采用浙江省龙游县农户竹林生产数据,运用超越对数的随机前沿生产函数模型,分析竹林地细碎化程度对竹林生产技术效率的影响。结果表明:随机前沿生产函数的误差主要是由技术非效率引起的,劳动力、资本、竹林地面积的产出弹性分别为0.20475,0.27136,0.11937;目前农户竹林生产技术效率低下,仅达到37.04%,有较大的提升空间;竹林地细碎化程度对竹林生产技术效率的影响不显著,但竹林地立地质量、农户是否参与竹林生产技术培训等因素对竹林生产技术效率产生显著影响。基于此,提出加强劳务的输入及资本投入、不断改善竹林地立地质量、加强对农户竹林生产的技术培训等建议。
採用浙江省龍遊縣農戶竹林生產數據,運用超越對數的隨機前沿生產函數模型,分析竹林地細碎化程度對竹林生產技術效率的影響。結果錶明:隨機前沿生產函數的誤差主要是由技術非效率引起的,勞動力、資本、竹林地麵積的產齣彈性分彆為0.20475,0.27136,0.11937;目前農戶竹林生產技術效率低下,僅達到37.04%,有較大的提升空間;竹林地細碎化程度對竹林生產技術效率的影響不顯著,但竹林地立地質量、農戶是否參與竹林生產技術培訓等因素對竹林生產技術效率產生顯著影響。基于此,提齣加彊勞務的輸入及資本投入、不斷改善竹林地立地質量、加彊對農戶竹林生產的技術培訓等建議。

The technical efficiency of forestry production plays a crucial role in the forestry production development. This study was based on the bamboo production data in Longyou county,Zhejiang province,and analyzed the forestland fragmentation impact on the bamboo production technical efficiency with the stochastic frontier production function model of translog form. The results showed that the error of stochastic frontier production function was mainly caused by technical inefficiency. The output elasticity of labor,capital,and bamboo area were 0. 204 75,0. 271 36,0. 119 37;Currently the farmers’bamboo production efficiency is low,only 37. 04%,and therefore has large room to improve; Effects of the bamboo land fragmentation on the bamboo production technical efficiency was not very significant,but site quality of bamboo plots,and farmers attending in bamboo production training had a significant effect on bamboo production technical efficiency. Based on this study,suggestions,such as to strengthen the capital input and labor input,and continuously improve the bamboo forest site quality,strengthen technical training for farmers’bamboo production,are put forward.
