为了研究区域航空物流网络空间结构特征及优化布局问题,在关系数据的基础上,采用社会网络分析(Social Network Analysis,SNA)方法,构建了一种针对有向多值型网络空间结构的量化分析体系。运用核心–边缘结构、凝聚子群、伯特结构洞以及拓扑分析模型,选取核心度、边关联度、限制度、等级度和冗余度5个定量指标从分布特征、群聚特征、连接机制和凝聚性4个角度对云南省航空物流网络的空间结构特征进行了描述和分析。结果显示:云南省航空物流网络以昆明为核心呈中心发散的状态,西双版纳、丽江和大理形成的次级区域对中心节点昆明的依赖性过高;昆明、西双版纳、大理及丽江间的连接稳定性、密集性强度较高,网络内部空间组织分化比较明显;核心区与密集区集中于旅游热点区域,空间布局较少兼顾与产业布局和跨境口岸之间的衔接。最后结合指标测算分析结果和云南省过境物流、东盟贸易的需求,充分利用现有交通资源,提出以昆明-西双版纳为“双核”的“双环形航空走廊”网络的空间布局优化建议。
In order to study the spatial structure and optimization layout of regional aviation logistics network, based on the relational data, a social network analysis (SNA) method is used to construct a quantitative analysis of the spatial structure of directed multivalue network system. Using core-edge structure, cohesive subgroups, Burt structure holes and topological analysis model, five quantitative indexes including core degree, edge correlation degree, limit degree, grade degree and redundancy are selected from the distribution characteristics, cluster characteristics, And cohesion of the four angles of the aviation logistics network in Yunnan Province, the characteristics of the spatial structure were described and analyzed. The results show that the air logistics network in Yunnan Province diverges from the center of Kunming. The secondary areas formed by Xishuangbanna, Lijiang and Dali are too dependent on the central node Kunming. The connection stability between Kunming, Xishuangbanna, Dali and Lijiang , The intensity of intensiveness is relatively high, and the organizational differentiation of the internal space of the network is obvious. The core areas and dense areas are concentrated in the hot spots of tourism, and the space layout is less balanced with the industrial layout and the interface between cross-border ports. Finally, based on the results of index analysis and calculation, the demand of cross-border logistics in Yunnan Province and the trade of ASEAN, and making full use of the existing traffic resources, this paper puts forward the optimization of the spatial layout of “double-ring” corridor with Kunming-Xishuangbanna as “dual-core” .
