摘　　要：西部陆海新通道的建设和完善是推动西部地区经济高质量发展的重要动力。运用带有非期望产出的超效率EBM模型测度2015—2021年西部陆海新通道沿线12个省域的物流业碳排放效率,引入修正后的引力模型、社会网络分析法和QAP模型等方法探究物流业碳排放效率的空间关联网络结构特征及影响因素。结论表明:(1)西部陆海新通道物流业碳排放效率波动上升,核心覆盖区始终高于辐射延展带;省域间差异明显,整体呈现出“东高西低”的空间分布格局。(2)省域间物流业碳排放效率的关联强度不断加强,网络结构愈发紧密,网络中森严的等级结构正在被打破;重庆、四川、广西在关联网络中处于核心地位;块模型分析结果显示网络逐渐形成有序的板块化分布。(3)地理邻近、经济发展水平、城镇化水平、科技创新水平、对外开放水平、环境规制强度的差异对空间关联网络产生不同程度的影响。The construction and improvement of the Western Land Sea New Corridor is an important driving force for promoting high-quality economic development in the western region.Using the super efficient EBM model with unexpected output to measure the carbon emission efficiency of the logistics industry in 12 provinces along the Western Land Sea New Corridor from 2015 to 2021,this study introduces modified gravity models,social network analysis,and QAP models to explore the spatial correlation network structure characteristics and influencing factors of carbon emission efficiency in the logistics industry.The conclusion shows that:(1)the carbon emission efficiency of the logistics industry in the western land sea new channel shows a fluctuating increase,with the core coverage area consistently higher than the radiation extension zone;There are significant differences between provinces,presenting an overall spatial distribution pattern of“high in the east and low in the west”.(2)The correlation strength of carbon emission efficiency in the logistics industry between provinces has been strengthened,the network structure is becoming increasingly tight,and the strict hierarchical structure in the network is being broken;Chongqing,Sichuan,and Guangxi are at the core of the interconnected network;The block model analysis results show that the network gradually forms an ordered block distribution.(3)The differences in geographical proximity,economic development level,urbanization level,technological innovation level,level of openness to the outside world,and environmental regulation intensity have varying degrees of impact on spatial connectivity networks.
