劳动力老龄化对竹林地利用效率的影响——基于中介效应的实证研究

关键词：
劳动力老龄化;竹林地利用效率;中介效应;安吉县
摘  要：
【目的】研究劳动力老龄化对林地利用效率的影响,以提高林地生产力水平。【方法】基于浙江省安吉县6个行政村112户农户256块竹林地块微观调查数据,通过构建劳动力老龄化、竹林地投入量、竹林地利用效率三者间的影响路径,运用中介效应分析模型对所构路径进行实证验证。【结果】劳动力老龄化不仅对竹林地利用效率产生直接正向影响,而且通过竹林地投入量这一中介变量对竹林地利用效率产生间接正向影响;效应测算结果显示,劳动力老龄化率的直接效应为0.288,竹林地投入量产生的间接效应为0.196。在其他控制变量中,家庭劳动力规模、竹林收入占比对竹林地投入量均有显著正向影响,而家庭经营竹林地面积、竹林地距家距离对竹林地投入量均有显著负向影响;劳动力健康水平、受教育年限、竹林收入占比及竹林地质量对竹林地利用效率均有显著正向影响,而竹林地块数对竹林地利用效率具有负向影响。【结论】农村劳动力老龄化并不是提高竹林地利用效率的障碍因素,老龄劳动力从事竹林生产提高了竹林生产的集约化程度,提高了竹林地的利用效率,但这种优势可能会受到林业现代水平不断提高的冲击。基于此,提出提高竹林生产的技术和机械化水平、加强老龄劳动力的人力资本投入、加快竹加工产业的发展、改善竹林地立地质量及细碎化程度等建议。

摘  要：
【Objective】Investigating the effect of aging labor force on forest land-use efficiency is to improve the productivity of forest land.【Method】Using the input-output data of 256 bamboo plots of 112 surveys from 6 administrative villages in Anji county in Zhejiang province, this paper constructed the influence path among the aging of labor force, bamboo land investment and bamboo land-use efficiency. Then, the mediating effect analysis model was used to test the rationality of influence.【Result】Not only was there direct positive effect on bamboo land-use efficiency by the aging of labor force, but also the indirect positive effect through bamboo land investment on bamboo land-use efficiency by the aging of labor force was significant. Measuring result of the influencing effects showed that the direct influence was 0.288 and mediating effect by bamboo land investment was 0.196. In control variables, significantly positive influence on bamboo land investment were found for factors such as family labor force, income ratio for bamboo production compare to total income; while the following elements showed significantly negative effects for bamboo land investment: the total area of bamboo plot, the distance to home. Health status and the years of education of labor force, income ratio for bamboo production compare to total income, and site quality of bamboo plots had significantly positive influence on bamboo land-use efficiency, and the number of bamboo plots had significantly negative influence on it.【Conclusion】The aging of rural labor force was not an obstacle to improve bamboo land-use efficiency, and aging labor force engaged in the production of bamboo increased the degree of intensification of bamboo production and improved bamboo land-use efficiency, but this advantage may be affected by the change of forestry production technology. Based on this study, some suggestions were put forward, such as improve the technology and mechanization of bamboo production, increase the human capital investment of aging labor force, accelerate the development of bamboo processing industry, and continuously improve the site quality and fragmentation of bamboo land.
