摘　　要： 利用浙江省安吉县6个行政村101户农户243块竹林地块的相关数据,采用超越对数的随机前沿生产函数模型,分析了劳动力老龄化对竹林生产技术效率的影响。实证结果显示:劳动力老龄化降低了竹林生产技术效率。样本地区竹林生产平均技术效率仅为66.68%,效率损失严重;随机前沿生产函数的误差主要来源于技术非效率,劳动力要素、土地要素及资本要素的产出弹性分别为0.249 2、0.358 9、0.252 8;在控制变量中,竹林收入比例、家庭劳动力规模及竹林地是否为租入地块对竹林生产技术效率产生显著正向影响;家庭经营竹林地块数对竹林生产技术效率产生显著负向影响。因此,提出提高竹林生产资本投入量及农户竹林生产收入水平、建立和完善林地流转机制以便降低林地细碎化程度、加强农村劳动力的人力资本投入等提高竹林生产技术效率的对策建议。 ⑴Background——With the acceleration of urbanization process in China,structure of rural labor force has undergone tremendous changes.The accelerated outflow of rural youth labor force result a large number of old labor force engaged in agricultural production in rural areas.The aging of labor force has an important influence on the development of rural economy.So it is necessary to improve forestry production technical efficiency through clarify the relationship between the aging of labor force and forestry production.⑵Methods——This research selected bamboo as the object of research,people above 60 years old as an indicator of the aging of labor force and 6 administrative villages in Anji County as the study area.Then 120households were selected for questionnaires in July 2015,and 101 valid questionnaires were got.Among the valid questionnaires,243 bamboo plots were surveyed in detail.Subsequently,the translog stochastic frontier production function was measured by frontier software.This research discussed the following questions:Firstly,whether the aging of labor force affecting the bamboo production technical efficiency or not?Secondly,what are factors affecting the bamboo production technical efficiency?⑶Results——The results of likelihood ratio hypothesis testing imply that:The Cobb-Douglas production function is not suitable for this research,and the bamboo production technical efficiency changes were affected by some environmental variables.According to the results of the translog stochastic frontier production function,the input of labor factor,land factor and capital factor had a significant positive influence on the output of bamboo.Bamboo output capacity per unit area with high in Anji County,but there exists excess labor with the increasing labor input and capital use degree are not high.The error of stochastic frontier production function model was aroused mainly by technical efficiency loss,and the output elasticity of labor factor,land factor and capital factor were 0.249 2,0.358 9,0
