摘要:
基于福建省三明市的163 户农户调查数据,采用DEA-Tobit 模型分析了毛竹林地经营规模效率及其影响因
素。在效率测算方面,福建省样本调查地区单户经营的毛竹林的总体规模效率平均为0.91,而林地平均规模效率
为0.86。可以看出,毛竹林总体经营规模效率较高,但林地这一要素的规模效率较低。单户经营林地最优规模为
60 ~70 亩(4 ~4.67 hm2 ),总体投入产出要素配置比例相对协调,但中小规模经营面积的农户经营效率仍有待提
高。在分析影响因素方面,家庭劳动力数量、从事林业经营活动经验、林地面积与毛竹林经营规模效率存在正相关
关系;户主性别、年龄、生产周期投工费用与规模效率呈反向变动关系。提出因地制宜确立林地经营效率最优适度
规模、加大力度扶持中小规模林地经营农户、加强林业经营者队伍质量建设等建议。

Abstract:
Based on the survey data of 163 households in Sanming of Fujian, DEA-Tobit model was
used to analyze the scale efficiency and influencing factors of single-household operation on bamboo
forestland. In terms of efficiency estimates, the average overall scale efficiency of operation on bamboo
forest by single-household farmer in the surveyed area of Fujian Province was 0.91, and the average scale
efficiency of forestland was 0.86, from which it could be seen that the scale efficiency of overall operation
on bamboo forest was high, but the scale efficiency of forestland as a factor was low. The optimal size of
single-household operation of forestland was 4 ~4.67 hm2, which allowed the allocation ratio of the input
to output element to be relatively coordinated well, however, the operation efficiency of farmers with
small-or middle-scales still need to be improved. Regarding the influence factors, there was a positive
correlation between the scale efficiency of operation on bamboo forest and the influencing factors of the
number of family labors, the experience of forestry management engagement, and forest area; while the
gender and age of householder, and costs in production period showed the reverse changes in the
relationship with scale efficiency. Finally, according to the analysis of the factors affecting the scale
efficiency, the following suggestions were proposed, i. e. , determining the proper size for optimal scale
efficiency of forestland based on the specific situation of local, fully supporting the famers with middle-or
small-scales of bamboo forestland, and enhancing the capabilities of forestry operators.
