农村家庭用能消费结构变化趋势研究——山东省郯城县实证分析

Trend analysis of energy consumption structure of rural household in Tancheng County

以山东省郯城县为案例,通过实地调研和问卷调查,将截面与时间序列相结合,深入细致地分析近年来农村家庭用能消费结构发生的变化。研究发现:村民家庭用能的消费结构已由20世纪90年代以前的"煤+薪柴"为主,变成"电+太阳能+煤"为主,液化气、薪柴为辅;既表现出电对煤、液化气对薪柴的替代,同时也显示出电和沼气对液化气的替代效应;村民家庭用能的增长主要来源于太阳能、电及沼气等农村非传统能源,且增长的能源主要用于生活享受;新能源和可再生能源成为农村家庭用能消费新的增长点。

With Tancheng County in Shandong Province as a case study,the energy consumption structure of rural household was deeply analyzed combining the methods of time slice analysis and time series analysis based on field survey and questionnaire investigation.The results showed that the major energy source of coal and crop straw in 1990s had been replaced by solar energy,electric energy and coal,and the crop straw had degraded to the secondary energy source,reflecting the substitution effect of rural energy consumption,e.g.,coal was replaced by electrical energy,crop straw was replaced by liquefied petroleum gas,and liquefied petroleum gas was replaced by electrical energy and methane.The new and renewable energy turned to be the new growth point of rural household energy consumption,for the increase of energy consumption was mainly from the nontraditional energy,such as solar energy,electric energy and methane,which was mainly used to improve the rural living levels.
