Analysis on the determinants of Phyllostachys edulis’s input-output efficiency

摘要: 如何提高林业生产效率对促进林农增收、促进山区经济发展具有重要的现实意义。以浙江省龙游县为例,采取两阶段分析的方法:首先应用数据包络分析(DEA)对竹农生产效率进行测度和判断,对不同地块规模毛竹Phyllostachys edulis的生产效率进行比较分析,探讨最合适规模。在生产效率测度的基础上,运用Tobit模型对竹农综合技术效率的影响因素进行分析,找出主要影响因素。结果表明:龙游县的竹农生产效率较低,综合技术效率均值为0.448,纯技术效率均值为0.569,规模效率均值为0.789;毛竹收入占比和地块立地质量对毛竹生产的综合技术效率具有正向影响,毛竹块数对毛竹生产的综合技术效率有显著的负向影响,流入地块的综合技术效率要低于非流入地块。图1表4参17

Abstract: Improving forestry input-output efficiency is significant for increasing farmers income and developing economy in mountainous areas. This paper took the bamboo production in Longyou County, Zhejiang Province as an example, and conducted a two-stage analysis: measuring bamboo farmers input-output efficiency with DEA and comparing the input-output efficiency of bamboo plots with different scales to identify the optimum scale; analyzing the factors affecting the bamboo farmers technical efficiency with the Tobit model on the basis of the measured production efficiency to find out the main determinants. The results indicated that the production efficiency of bamboo famers in Longyou county was comparatively low: average value of comprehensive technical efficiency, net technical efficiency and scale efficiency being 0.448, 0.569 and 0.789 respectively. The ratio of bamboo income to total household income and site quality of bamboo plot had a positive impact on comprehensive technical efficiency, while the number of bamboo plots had a negative impact on comprehensive technical efficiency. The comprehensive technical efficiency of transferred plots was lower than that of non-transfer plots.[Ch, 1 fig. 4 tab. 17 ref.]-
