摘要
测算2000年-2020年长江经济带交通碳排放量,应用修正后的引力模型,构建长江经济带交通碳排放关联网络,采用社会网络分析方法分析碳排放网络整体特征与个体特征,并运用QAP分析法探析整体网络的影响因素。结果表明,长江经济带交通碳排放显著增加,整体网络结构朝着紧密化和复杂化的趋势前进,且存在不均衡性。经济发展水平差距、人口密度差异、货运周转量差异、行政区面积差异对长江经济带交通碳排放空间溢出效应具有正向的显著影响,地理距离差异、交通碳排放强度差异对其产生负向影响。
This paper calculates the transport carbon emissions in the Yangtze River Economic Belt from 2000 to 2020 by appling the modified gravity model to build a transport carbon emissions correlation network in the Yangtze River Economic Belt.It uses social network analysis methods to analyze the overall characteristics and individual characteristics of the carbon emissions network.The QAP analysis method is used to analyze the influencing factors of the whole network.The results show that the carbon emissions from transportation in the Yangtze River Economic Belt have increased significantly,and the overall network structure is moving towards a trend of compactness and complexity,and there are imbalances.The differences in economic development level,population density,freight turnover,and administrative area have a positive and significant impact on the spatial spillover effect of transport carbon emissions in the Yangtze River Economic Belt.The differences in geographical distance and transport carbon emission intensity have a negative impact.
