Abstract
It is of great significance for the scientific formulation or adjustment of rural energy policy in the new era to explore the current situation of rural household biogas utilization and make a comprehensive evaluation of the benefits of biogas and its derivatives. Based on the field survey data of Qionglai, Sichuan Province, this study uses AHP to build a comprehensive evaluation index system, uses financial indicators to calculate the economic benefits of household biogas, and establishes the weight and score of the index system to comprehensively evaluate the economic, ecological and social benefits of biogas and its derivatives utilization in the survey area. The research results show that the economic benefits and social benefits of rural household biogas are good, but the ecological benefits are not up to the ideal level. Under the background of rapid development of new rural construction and urbanization, the government still needs adjusting policies, so as to meet the challenges of structural changes in the domestic energy consumption market.
