西北生态脆弱区清洁能源推广迫在眉睫,收入是农村能源消费的重要因素。基于969户农村家庭数据,采用二元Logistic模型,分析收入水平对西北生态脆弱区农村家庭清洁能源使用行为的影响,并剖析其异质性。结果表明:收入水平对西北生态脆弱区农村家庭不同用途中清洁能源使用行为的影响存在差异,并存在空间异质性。收入水平提高,清洁取暖比例远低于其他用途的黄土高原生态脆弱区,清洁取暖的概率增长最多;各用途清洁能源使用率较高、差异小的西北干旱荒漠生态脆弱区,成本低的烹饪概率增长更多。然而,在清洁能源使用率最低、高收入牧民居多的青藏高原生态脆弱区,3种用途中收入水平的影响不显著。基于此,为西北生态脆弱区农村能源转型提供了政策参考。

The promotion of clean energy in ecologically fragile areas in Northwest China is imminent, and income is an important factor in rural energy consumption. Based on the data of 969 rural households, the binary logistic model is used to analyze the impact of income level on clean energy use behavior of rural households in ecologically fragile areas in Northwest China, and its heterogeneity. The results reveal that there are differences and spatial heterogeneity in the impact of income level on rural household clean energy use behavior of different types of use in ecologically fragile areas in Northwest China. With the increase of income level, in ecologically fragile area on Loess Plateau, where the proportion of clean heating is far lower than that of other types of use, the probability of clean heating increases the most. In ecologically fragile area on desert areas in Northwest China, where the utilization rate of clean energy for various types of use is high and the difference is small, the probability of cooking with low cost increases the most. However, in ecologically fragile area on Qinghai Tibet Plateau, where clean energy utilization rate is the lowest and high-income herdsmen are the majority, the impact of income levels in three types of uses is not significant. Based on this, it provides policy reference for the rural energy transformation in ecologically fragile areas in Northwest China.
