【摘要】 在碳排放的影响因素中,城镇化可能是最根本、潜在影响最大的因素。文章在系统梳理了国内外相关文献基础上,对城镇化作用于碳排放的效应及其空间尺度差异、基于空间关联效应的城镇化对碳排放的影响等问题等进行了归纳与总结,发现:城镇化对碳排放的作用效应主要包括3个方面,即城镇化对碳排放的总效应、城镇化对碳排放的直接效应和城镇化通过中介变量对碳排放产生的间接效应。但现有文献的研究内容主要集中在城镇化对碳排放的总效应以及城镇化对碳排放的直接效应,对城镇化对碳排放产生的间接影响的研究重视不够;现有研究将研究单元视为相互独立且均质的个体空间,普遍忽略了地区间的空间效应问题。另外,现有研究结果具有尺度依赖性,且中国现行的行政管理体系是分层嵌套结构,但现有研究普遍忽略了空间尺度差异、缺乏多尺度空间的对比研究,对研究区域所具有的分层嵌套结构特征重视不够,缺乏系统的建模与分析。最后提出应加强城镇化对碳排放作用的多学科交叉研究、扩展城市群与县域尺度的研究、城镇化对碳排放作用全效应的系统研究以及空间效应视角下城镇化与碳排放关系的多尺度空间对比与多尺度空间关联效应研究的建议与展望,以期为相关研究提供有益借鉴。更多还原

【Abstract】 The urbanization may be the most fundamental and potential factor affecting in carbon emissions. On the basis of domestic and foreign literature review, this paper summarizes the effects of urbanization on carbon emissions and its spatial scale differences and the impact of urbanization on carbon emissions based on spatial correlation effects. The results show that there are three parts about the effect of urbanization on carbon emissions, that is, the total effect of urbanization on carbon emissions, the direct effect of urbanization on carbon emissions and the indirect effect of urbanization on carbon emissions through mediator variables. However, the existing studies mainly focu on the total effect and the direct effect of urbanization on carbon emissions, and ignore the indirect effect of urbanization on carbon emissions. Moreover, The present research regards the research units as independent and homogeneous individual spaces, and generally ignores the spatial effects of the regions. In addition, the result of existing studies depend on different scales, but ignore the differences in spatial scales and lack comparative studies of multi-scale space. Meanwhile, although China’s current administrative management system is hierarchical nested structure, the present research paid little attention on the layered nested structure of the research unit and systematic modeling and analysis. Finally, In order to provide reference for similar studies, suggestions are proposed that scholars should strengthen the multi-disciplinary research on the role of urbanization in carbon emissions, expand the research on urban agglomerations and county scales, the systematic study on the full effect of urbanization on carbon emissions and the multi-scale spatial contrast and multi-scale spatial correlation of urbanization on carbon emissions from the perspective of spatial effect.更多还原
