少数民族地区农村家庭生活能源消费需求研究——以甘肃省、云南省为例

Empirical Study on Rural Households' Demand for Energy Consumption in Western Ethnical Minority Areas——Evidence from Gansu and Yunnan Province

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 a household survey in western ethnical minority areas of Gansu and Yunnan province, this paper first describes rural households＇ energy consumption pattern, and further investigates the relevant factors determining households＇ demand for fuelwood consumption by using a Tobit model. The empirical results show that sample households have strong dependence on fuelwood consumption. The commercial energy such as coal and electricity have not played a significant substitute effect for fuelwood, while households who use biogas have significantly decreased fuelwood consumption. In addition, fuelwood consumption increases with household wealth,whereas the off-farm income ratio has produced a significant and negative effect on fuelwood consumption. We futher find that Minority households have consumed more fuelwood than Han majority.
