物流产业集聚对碳中和效果的作用测度及其作用机制

Measurement of Effect and Action Mechanism of Logistics Industrial Agglomeration on Carbon Neutrality

以物流业为研究对象,基于除了西藏、港澳台的中国30个省(直辖市、自治区)的面板数据,采用固定效应模型实证分析物流产业集聚对碳中和效果的影响及其作用机制。结果表明,物流产业集聚对碳中和效果有着显著的正向影响,该结论经过一系列的稳健性检验后依然成立。进一步分析发现,物流产业集聚主要通过扩大经济规模、优化产业结构和扩大城市绿地面积等途径促进碳中和效果的实现。异质性分析表明物流产业集聚对东中西部碳中和效果的驱动效应存在异质性,具体表现为物流产业集聚对西部碳中和效果发挥显著的促进效应;最后纳入交互项进行调节检验,发现物流产业集聚对碳中和效果影响系数的显著性未发生实质性的变化,厘清物流产业集聚对碳中和效果的作用测度及其作用机制对实现碳中和效果具有重要的意义。

Taking the logistics industry as the research object,and based on the panel data of 30 provinces(municipalities and autonomous regions)in China,we used the fixed effect model to empirically analyze how logistics industrial agglomeration influenced carbon neutrality and its mechanism of action.The result showed that logistics industrial agglomeration had significant positive impact on carbon neutrality,which holds true after a series of robustness tests.Through further analysis,it was found that logistics industrial agglomeration mainly supports carbon neutrality via economic scale growth,industrial structure optimization,and urban green space expansion,etc.Through a heterogeneity analysis,it was shown that heterogeneity exists in the driving effect of logistics industrial agglomeration on carbon neutrality in the eastern,middle and western regions.More specifically,logistics industrial agglomeration has the most significant promoting effect on carbon neutrality in the western region.Finally,by including the interactive terms in an adjustment test,we found that the influence coefficient of logistics industrial agglomeration on carbon neutrality has not changed substantially and then clarified how to measure the impact of logistics industrial agglomeration on carbon neutrality and its mechanism of action in achieving carbon neutrality.
