林业雇工劳动质量对农户营林技术效率的影响

以浙江省245户样本农户的调研数据为基础，利用随机前沿生产函数方法测度样本农户营林技术效率，分析影响农户营林技术效率的因素，重点分析雇工劳动质量对农户营林技术效率的影响。结果表明:样本地区农户营林的平均技术效率为0.57，存在着明显的技术效率损失；有雇工农户的营林技术效率的平均值为0.59，无雇工农户的营林技术效率的平均值为0.76，农户营林生产过程中雇佣劳动的存在会阻碍农户营林技术效率的提高，对营林生产造成负面影响。实证分析发现:农户营林生产过程中的雇佣劳动对营林生产有负面影响；雇工劳动质量不同，对提高农户营林技术效率的影响程度也不同；营林生产总投工中雇工所占比例越大，对提高农户营林技术效率的负面影响程度越大。基于此，提出推进适度规模经营并加大林业科技服务投入、建立有效的劳动监督和管理机制等建议。

Impact of the labor quality of hired forestry labor on the technical efficiency of farmers' forestry management

Drawing on the survey data of 245 farmer households in Zhejiang Province, this paper uses the Stochastic Frontier Approach (SFA) to measure the technical efficiency of the sample farmers' forestry management, and analyze the influencing factors of the technical efficiency, in particular the impact of labor quality of hired forestry labor on the technical efficiency of farmer's forest management. Results show that the average technical efficiency of farmer's forestry management in sample area is 0.57, and there is obvious loss of technical efficiency. The average technical efficiency of farmer households with hired labor is 0.59, and that of households without hired labor is 0.76. It shows that hiring labor in the process of farmer's forestry production will hinder the improvement of technical efficiency of farmer's forestry management and have a negative impact on the forestry production. Empirical analysis shows that hiring labor in the process of farmer's forestry production does have a negative impact on the forestation, and the different quality of the hired labor has different impact on improving the technical efficiency of farmer's forestry management:the greater the proportion of hired workers in the total labor input of forestry production, the greater the negative impact on improving the technical efficiency of farmers' forestry management will be. Based on the research findings, suggestions on promoting moderate scale operation, increasing investment in science and technology services, and establishing effective labor supervision and manage mechanism are proposed.
