中文摘要:

      绿色低碳的生活和生产方式是实现经济社会可持续发展的重要路径。家庭消费间接碳排放作为碳排放增长的新兴分支，由此展开空间关联网络研究，将为西部家庭因地制宜实施碳减排措施提供科学依据。本文结合投入产出法和消费者生活方式方法测算出2012—2021年西部地区10个省（区）的家庭消费间接碳排放量并分析其动态演进及空间关联情况。结果表明：①西部家庭消费间接碳排放量整体上升趋势变缓，城镇和乡村两者碳排放总量存在较大差异。②西部家庭消费间接碳排放空间关联网络整体呈现周期性波动趋势，网络结构相对松散，等级差异较明显，其中甘肃、贵州、内蒙古、陕西等处于关联网络中心位置，与其余区域存在密切的空间关联效应。③西部家庭消费间接碳排放空间关联网络通过板块间传导与溢出效应建立。甘肃、陕西等交通枢纽位置的省份多为要素的主要受益方，经济发展水平较高的省（区）多为要素的主要溢出方。西部家庭消费间接碳排放空间关联的紧密程度亟待提升，板块间联动效应和跨区域网络效应也应进一步提高，以促进西部地区家庭碳减排协同发展。

英文摘要:

      Green and low-carbon way of life and production is an important path for sustainable economic and social development. As an emerging branch of carbon emission growth, the study of the spatial correlation network of indirect carbon emissions from household consumption will provide a scientific basis for the implementation of carbon-reducing measures by households in western China according to local conditions. This paper combines the input-output method and the consumer lifestyle method to measure the indirect carbon emissions from household consumption in 10 provinces (autonomous regions) in the western region from 2012 to 2021, and analyzes their dynamic evolution and spatial correlation. The results show that: ① The overall rising trend of indirect carbon emissions from household consumption in the west has slowed down, and there is a big difference between the total carbon emissions in towns and villages. ② The overall indirect carbon emissions from household consumption in the west show obvious cyclical fluctuation trend, the network structure is relatively loose, the network hierarchical differences are more obvious, in which Gansu, Guizhou, Inner Mongolia, Shaanxi and other provinces (autonomous regions) are at the center of the associated network, not only having close spatial correlation with other provinces, but also playing the role of “intermediary”. ③ The main mode of action in the spatial correlation network of indirect carbon emissions from household consumption in the west is inter-plate transmission and spillover effects. Gansu, Shaanxi and other provinces in the transportation hub location are the main beneficiaries of each factor, and the provinces (autonomous regions) with higher economic development level are the main spillover of each factor. The closeness of the spatial correlation of indirect carbon emissions from household consumption in the west needs to be urgently improved, and the inter-plate linkage effect and cross-regional network effect should be further improved, in order to promote the synergistic development of indirect carbon emission reduction from household consumption in the western region.
