文章利用甘肃省和云南省少数民族地区322户农户的调查数据,在了解样本农户家庭生活能源消费模式的基础上,利用Tobit模型定量地分析了影响农户薪柴消费需求的因素。研究发现,样本农户对薪柴等传统生物能源仍有较强的依赖性。燃煤、电力等商品能源对薪柴的替代效应不明显,但使用沼气的农户对薪柴的消费显著减少。非农收入占家庭总收入比例的增加能显著减少农户的薪柴消费,但薪柴消费随着家庭财富的增加而增加。同时,发现少数民族家庭的薪柴消费量显著高于汉族家庭。
Based on the survey data of 322 households in Gansu and Yunnan minority areas, this paper used Tobit model to quantitatively analyze the factors that affect the consumption demand of fuelwood in rural households based on the understanding of household energy consumption pattern. The study found that sample farmers still have strong dependence on traditional bioenergy such as fuelwood. The substitute effect of commercial energy sources such as coal and electricity on fuelwood is not obvious, but the consumption of fuelwood by farmers using biogas is significantly reduced. The increase of the proportion of non-agricultural income in total household income can significantly reduce the consumption of fuelwood by farmers, but the consumption of fuelwood fuel increases with the increase of household wealth. At the same time, it was found that firewood consumption of ethnic minority families was significantly higher than that of Han families.
