Analysis of farmers’ willingness to adopt small scale household biogas facilities

摘要: 因地制宜, 结合实际, 充分考虑农户意愿和承受能力是小型户用沼气建设、推广取得成功的关键。本文对河北平原农村小型户用沼气建设的现状及使用中存在的问题进行了问卷调查, 并运用Logistic 模型定量分析了影响小型户用沼气建设意愿的因素。结果表明, 调查区大多数农户愿意建设和使用小型户用沼气, 小型户用沼气的建设信息主要来源于沼气技术推广部门, 技术和信息来源单一; 小型户用沼气建设的服务体系有待改进。农民参与小型户用沼气建设的意愿与受教育程度呈显著负相关, 与农户人均纯收入和劳动力占家庭总人口比重呈显著正相关。因此, 在农村小型户用沼气建设制度设计中, 不仅要充分考虑农民的保障需求水平和经济承受能力, 兼顾制度的公正与效率, 还要充分考虑农户家庭成员的个人特征、家庭特征和生产经营特征。结合相关部门提供的服务、政府支持等多种因素促进小型户用沼气的推广应用。

Abstract: Adapting small scale household biogas to the conditions of local farmer households is crucial for the success of the technology. A survey was conducted in 2009~2010 on the current state of biogas facility construction and the problems related with using the facilities in Hebei Plain. A logistic model was built to quantitatively analyze the factors affecting farmers’ will to adopt small scale household biogas facilities in the region. Results showed most farmers were willing to adopt the facility. And governmental biogas extension section was the main resource for the farmers to learn the small scale household biogas. The service system needed to be improved to facilitate the application of the facility. The affecting factors analysis showed that low education levels of household heads negatively influenced the will to adopt the technology. Per-capita net income of farm families and excess labor in families were positively correlated with farmers’ will. Therefore, for developing the small scale household biogas facilities in rural areas, not only farmers’ needs and economic abilities were important, system equity and efficiency were also key points. The personal characteristics of farm family members, features of households and household agro-enterprises were critical too. A comprehensively sustainable adoption required provision of services and supports by the relevant sectors and government. -
