农村劳动力转移对竹林生产效率的影响研究

基于浙江省龙游县5个行政村115户农户268块竹林地投入产出数据,采用DEA模型对竹林生产效率进行测度,运用Tobit模型进行计量分析,从空间和时间角度分析劳动力转移对竹林生产效率的影响。结果表明:竹林地的综合效率、纯技术效率及规模效率的均值分别为0.470、0.560及0.842,竹林地的生产效率相对较低;劳均非农就业时间、劳动力转移类型的复合性、竹林收入占家庭收入比例及户主年龄对竹林地生产效率有显著正向影响,家庭竹林地总块数对竹林地生产效率有显著的负向影响。因此,提出改善竹林投入、提高生产效率的相关对策建议。

The Impacts of Rural Labor Migration to Bamboo Production Efficiency

Using the input-output data of 268 bamboo plantations collected from 115 households in 5 counties of Zhejiang, the paper analyzed the impacts of rural labor migration to bamboo production ef-ficiency from the perspective of space and time. Using DEA model, the paper measured the bamboo production efficiency. The results show that: the mean of the comprehensive technical efficiency val-ue, the pure technical efficiency value and the scale efficiency value of bamboo forestland is 0. 470, 0. 560 and 0. 842 respectively. The results of Tobit regression model showed that non-agricultural em-ployment time per labor, composite labor migration, the ratio of bamboo income to total family income and age of the householder has significant positive effect on bamboo production efficiency; the total number of bamboo forestland have a significant negative impact on bamboo production efficiency. Fi-nally, the paper puts forward advices on promoting bamboo production efficiency.
