农户对可再生能源沼气选择的影响因素——以江苏省农村家庭户用沼气为例

Study on Influencing Factors of Choosing Renewable Energy Biogas——A Case Study on Rural Household Biogas in Jiangsu Province

通过抽样调查法及访谈法对江苏省农村户用沼气消费情况进行了实地调查。数据显示,使用沼气的家庭人均能源消费量低于未使用沼气的家庭,因为沼气对生物质能源有一定的替代作用,减少了秸秆、薪柴的大量粗放使用;同时也有助于能源结构的调整,提高新能源和商品能在家庭用能中所占的比重。对农户是否选择沼气的影响因素分析显示,政府提供资金和技术支持对促进农户选择使用沼气的推动作用最大,人均生猪饲养量、家庭留守人口中最高受教育年限与农户选择行为正相关,人均纯收入、家庭外出打工人口比例、农户位于粮食主产区、农户使用液化气与农户的选择行为负相关。

Based on the investigation for the consumption of the rural household biogas in Jiangsu, this paper concludes that per capita energy consumption of the family with biogas is lower than that without biogas, because biogas alternates biomass used by legging way and some commercial energy, and it also contributes to adjust the energy structure of raising the proportion of new energy and commodities. Furthermore, choosing biogas, for rural household, is influenced by many factors, of which the financial and technical support from government plays the biggest positive role. The raising of per capita amount of live pigs and the increase of the highest years of schooling of the staying-home population are positively related to the choice of biogas. However, if farmers live in major grain-producing area or use LPG, they will not choose biogas. And the per capita net income and proportion of the employed labor in a family act negative role： with their increase, farmers decline the probability of choosing biogas.
